I want to create a group-function to my Website. In every group there should be a group-image, which people can upload. So I must save the path into my SQL-DB. My Code:
newFileName = Guid.NewGuid().ToString() + "_" + Path.GetFileName(photo.FileName);
imagePath = #"images\" + newFileName;
imageThumbPath = #"images\thumbs\" + newFileName;
var setPath = (#"~\" + imageThumbPath);
var intoGroupImg = ("UPDATE groups SET img= " + #setPath+ " WHERE id= "+#grID);
db.Execute(intoGroupImg);
I always get the error-message: Token line number = 1,Token line offset = 26,Token in error = images. I don't know why.
I've got a solution:
var intoGroupImg = ("UPDATE groups SET img = #0 WHERE id= " +#grID);
db.Execute(intoGroupImg, imageThumbPath);
First off, please, please use parameterized queries. It is your smoking gun versus SQL injection. Even if you're not adding user-input, it is a good habit to get into.
Anyway, I'm not sure what some of your # symbols are in there for, but I am used to using C#.net with WebMatrix, but I think that is what you're using also. Try this:
var newFileName = Guid.NewGuid().ToString() + "_" + Path.GetFileName(photo.FileName);
var imagePath = "images/" + newFileName;
var imageThumbPath = "images/thumbs/" + newFileName;
var setPath = "~/" + imageThumbPath;
var intoGroupImg = "UPDATE groups SET img = #0 WHERE id = #1";
db.Execute(intoGroupImg, setPath, grID);
This is how I would imagine it to look in C# with parameterized queries.
Given the line offset I believe the error is from #setPath but I'm not sure. Try going to the database tab in WebMatrix and manually doing a query with what you expect the value of #setPath to be.
Also, I noticed you used "backslashes" instead of "forward slashes" in the concatenated string in your example. Is this intentional? Is that what the # symbol is doing? Keeping you from having to escape each backslash with \\? Either way, the forward slash / in its place should do fine, no?
Anyway, hope I helped, at least some.

Recently i got into MEL programming to help out a few friends in maya. They wanted to have their files refferenced on a server, so i needed to change the reff strings. Now i have compiled a solution to do this, and used another example as a guide, but when i run the script it says
// Error: int $nt=tokenize $TexturePath "\" $buff;
//
// Error: Line 12.43: Unterminated string. //
What gives?
p.s. full code below for anyone who wants to use it
string $SceneTextures[] = `ls -tex`;
string $plus="";//Place a file type here to be saved in that subfolder
for ($i = 0; $i< (`size $SceneTextures`); $i++)
{
$Test = catchQuiet(`getAttr ($SceneTextures[$i] + ".fileTextureName")`);
if ($Test == 0)
{
string $TexturePath = `getAttr ($SceneTextures[$i] + ".fileTextureName")`;
string $buff[];
int $nt=`tokenize $TexturePath "\\" $buff`;
string $newPath=("${ARC_SURF}\\" + plus + "\\" + $buff[$nt-3] + "\\" + $buff[$nt-2] + "\\" + $buff[$nt-1]);
setAttr -type "string" ($SceneTextures[$i] + ".fileTextureName") $NewPath;
catchQuiet (AEfileTextureReloadCmd ($SceneTextures[$i] + ".fileTextureName"));
//print $TexturePath;
}//end if
}//end for i
EDIT: Fixed the code as it should be, now it only throws // Error: line 14: Invalid negative index used to reference array "$buff".
But i think that probably only 1 texture screws stuff up, will check and report back
I'm no expert in MEL, but in many languages \ is used to escape control-sequences, so I would guess you want "\\" instead of "\", in the many places it appears.
I am trying to write a big project which involves of a lot of code. That's why I want to separate functionalities from different files.
the first file, dataJS, I make an AJAX call to get data from a JSON file.
the second file, showJS I want to display the data obtained from the dataJS file.
When it comes to implementation, I realise that AJAX call takes longer time and even though I include dataJS and showJS in order, showJS will still get a null data
therefore I made a function called continueFromDataJS() in showJS file
and call continueFromDataJS() at the end of the AJAX success function.
I think it's a rather makedo solution. Is there any standard way to do it?
In addition, all intellisense in my Visual Studio is gone. Despite separate files, is there any way to make visual studio get intellisense from the dataJS?
Thank you
sorry, I don't know how to add a follow up question
this is the code
for simplicity I rename some of the files and only take some part out of it. Hope that helps
code in html
code in dataJS.js
var planets = [];
var jsonData = null;

var data = jsonData.planets[pID].contents; // **this line won't get jsonData if it's out this curly brace.**
for (var i = 0; i < data.length; i++) {
$article.append(data[i].title);
$article.append(data[i].content);
}

don't forget to answer my intellisense question. I want in datajs.js automatically hint planets and jsonData declared in datajs.js
is it possible?
I'm looping through videos in the awaitKnownFolders.VideosLibrary.GetFilesAsync() method and first I thought something was wrong with my code, but on my machine with an SSD drive it takes some 5-20 seconds to get the files. The folder only contains 5 small files.
What is even stranger is that if I specify a subfolder with await KnownFolders.VideosLibrary.GetFolderAsync("subfolder") and then do await folder.GetFilesAsync() from that folder - it loops the files in a second!
I have the same symptoms in the PicturesLibrary. Is it just me? Maybe it's because the OS tries to load up "linked" video libraries from the network (this is my best guess)?
I think it's just you. This should work:
StorageFolder videosFolder = KnownFolders.VideosLibrary;
IReadOnlyList<StorageFile> fileList = await videosFolder.GetFilesAsync();
IReadOnlyList<StorageFolder> folderList = await videosFolder.GetFoldersAsync();
var count = fileList.Count + folderList.Count;
StringBuilder outputText = new StringBuilder(videosFolder.Name + " (" + count + ")\n\n");
foreach (StorageFolder folder in folderList)
{
outputText.AppendLine(" " + folder.DisplayName + "\\");
}
foreach (StorageFile file in fileList)
{
outputText.AppendLine(" " + file.Name);
}
OutputTextBlock.Text = outputText.ToString();
To test for yourself, run the Folder Enumeration Sample. That's where the above snippet is from.
I have a problem running the NativeProcess if I put spaces in the arguments
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
fPath = "C:\\Windows\\System32\\cmd.exe";
args.push("/c");
args.push(scriptDir.resolvePath("helloworld.bat").nativePath);
}
file = new File(fPath);
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
args.push("blah");
nativeProcessStartupInfo.arguments = args;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
in the above code, if I use
args.push("blah") everything works fine
if I use
args.push("blah blah") the program breaks as if the file wasn't found.
Seems like I'm not the only one:
http://tech.groups.yahoo.com/group/flexcoders/message/159521
As one of the users their pointed out, it really seems like an awful limitation by a cutting edge SDK of 21st century. Even Alex Harui didn't have the answer there and he's known to workaround every Adobe bug:)
Any ideas?
I am using AIR 2.6 SDK in JavaScript like this, and it is working fine even for spaces.
please check your code with this one.
var file = air.File.applicationDirectory;
file = file.resolvePath("apps");
if (air.Capabilities.os.toLowerCase().indexOf("win") > -1)
{
file = file.resolvePath(appFile);
}
var nativeProcessStartupInfo = new air.NativeProcessStartupInfo();
nativeProcessStartupInfo.executable = file;
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
process = new air.NativeProcess();
process.addEventListener(air.ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
process.addEventListener(air.ProgressEvent.STANDARD_INPUT_PROGRESS, inputProgressListener);
process.start(nativeProcessStartupInfo);
To expand on this: The reason that this works (see post above):
var args =new air.Vector["<String>"]();
for(i=0; i<arguments.length; i++)
args.push(arguments[i]);
nativeProcessStartupInfo.arguments = args;
is that air expects that the arguments being passed to the nativeProcess are delimited by spaces. It chokes if you pass "C:\folder with spaces\myfile.doc" (and BTW for AIR a file path for windows needs to be "C:\\folder with spaces\\myfile.doc") you would need to do this:
args.push("C:\\folder");
args.push("with");
args.push("spaces\\myfile.doc");
Hence, something like this works:
var processArgs = new air.Vector["<String>"]();
var path = "C:\\folder with spaces\\myfile.doc"
var args = path.split(" ")
for (var i=0; i<args.length; i++) {
processArgs.push(args[i]);
};
UPDATE - SOLUTION
The string generated by the File object by either nativePath or resolvePath uses "\" for the path. Replace "\" with "/" and it works.
I'm having the same problem trying to call 7za.exe using NativeProcess. If you try to access various windows directories the whole thing fails horribly. Even trying to run command.exe and calling a batch file fails because you still have to try to pass a path with spaces through "arguments" on the NativeProcessStartupInfo object.
I've spent the better part of a day trying to get this to work and it will not work. Whatever happens to spaces in "arguments" totally destroys the path.
Example 7za.exe from command line:
7za.exe a MyZip.7z "D:\docs\My Games\Some Game Title\Maps\The Map.map"
This works fine. Now try that with Native Process in AIR. The AIR arguments sanitizer is FUBAR.
I have tried countless ways to put in arguments and it just fails. Interesting I can get it to spit out a zip file but with no content in the zip. I figure this is due to the first argument set finally working but then failing for the path argument.
For example:
processArgs[0] = 'a';
processArgs[1] = 'D:\apps\flash builder 4.5\project1\bin-debug\MyZip.7z';
processArgs[2] = 'D:\docs\My Games\Some Game Title\Maps\The Map.map';
For some reason this spits out a zip file named: bin-debugMyZip.7z But the zip is empty.
Whatever AIR is doing it is fraking up path strings. I've tried adding quotes around those paths in various ways. Nothing works.
I thought I could fall back on calling a batch file from this example:
http://technodesk.wordpress.com/2010/04/15/air-2-0-native-process-batch-file/
But it fails as well because it still requires the path to be passed through arguments.
Anyone have any luck calling 7z or dealing with full paths in the NativeProcess? All these little happy tutorials don't deal with real windows folder structure.
Solution that works for me - set path_with_space as "nativeProcessStartupInfo.workingDirectory" property. See example below:
public function openPdf(pathToPdf:String):void
}
var nativeProcessStartupInfo:NativeProcessStartupInfo = new NativeProcessStartupInfo();
var file:File = File.applicationDirectory.resolvePath("C:\\Windows\\System32\\cmd.exe");
nativeProcessStartupInfo.executable = file;
if (Capabilities.os.toLowerCase().indexOf("win") > -1)
{
nativeProcessStartupInfo.workingDirectory = File.applicationDirectory.resolvePath(pathToPdf).parent;
var processArgs:Vector.<String> = new Vector.<String>();
processArgs[0] = "/k";
processArgs[1] = "start";
processArgs[2] = "test.pdf";
nativeProcessStartupInfo.arguments = processArgs;
process = new NativeProcess();
process.start(nativeProcessStartupInfo);
process.addEventListener(ProgressEvent.STANDARD_OUTPUT_DATA, onOutputData);
}
args.push( '"blah blah"' );
Command line after all supports spaces if they are nested whithin "".
So if lets say you have a file argument :
'test/folder with space/blah'
Convert it to the following
'test/"folder with space"/blah'
Optionally use a filter:
I once had a problem like this in AIR, i just simply filter the text before i push it into the array. My refrence use CASA lib though
import org.casalib.util.ArrayUtil;
http://casalib.org/
/**
* Filters a string input for 'safe handling', and returns it
**/
public function stringFilter(inString:String, addPermitArr:Array = null, permitedArr:Array = null):String {
var sourceArr:Array = inString.split(''); //Splits the string input up
var outArr:Array = new Array();
if(permitedArr == null) {
permitedArr = ("abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ1234567890" as String).split('');
}
if( addPermitArr != null ) {
permitedArr = permitedArr.concat( addPermitArr );
}
for(var i:int = 0; i < sourceArr.length; i++) {
if( ArrayUtil.contains( permitedArr, sourceArr[i] ) != 0 ) { //it is allowed
outArr.push( sourceArr[i] );
}
}
return (outArr.join('') as String);
}
And just filter it via
args.push( stringFilter( 'blah blah', new Array('.') ) );
Besides, it is really bad practice to use spaces in file names / arguments, use '_' instead. This seems to be originating from linux though. (The question of spaces in file names)
This works for me on Windws7:
var Xargs:Array = String("/C#echo#a trully hacky way to do this :)#>#C:\\Users\\Benjo\\AppData\\Roaming\\com.eblagajna.eBlagajna.POS\\Local Store\\a.a").split("#");
var args:Vector.<String> = new Vector.<String>();
for (var i:int=0; i<Xargs.length; i++) {
trace("Pushing: "+Xargs[i]);
args.push(Xargs[i]);
};
NPI.arguments = args;
If your application path or parameter contains spaces, make sure to wrap it in quotes. For example path of the application has spaces C:\Program Files (x86)\Camera\Camera.exe use quotes like:
"C:\Program Files (x86)\Camera\Camera.exe"
To solve a problem listed here I've got to change the InstallExecuteSequence .RemoveExistingProducts record in an MSI.
I want to do this as part of the build process rather than mucking around with Orca
Modifying the MSI_SetProperty.js script gives
// MSI_SetActionSequence.js <msi-file> <table> <action> <sequence>
// Performs a post-build fixup of an msi to set the specified table/action/sequence
// Constant values from Windows Installer SDK
var msiOpenDatabaseModeTransact = 1;
var msiViewModifyInsert = 1;
var msiViewModifyUpdate = 2;
var msiViewModifyAssign = 3;
var msiViewModifyReplace = 4;
var msiViewModifyDelete = 6;
if (WScript.Arguments.Length != 4)
{
WScript.StdErr.WriteLine("Usage: " + WScript.ScriptName + " file table action sequence");
WScript.Quit(1);
}
var filespec = WScript.Arguments(0);
var table = WScript.Arguments(1);
var action = WScript.Arguments(2);
var sequence = parseInt(WScript.Arguments(3));
var installer = WScript.CreateObject("WindowsInstaller.Installer");
var database = installer.OpenDatabase(filespec, msiOpenDatabaseModeTransact);
WScript.StdOut.WriteLine("Looking for action:" + action);
try
{
var sql = "SELECT Action, Sequence FROM " + table + " WHERE Action = '" + action + "'";
var view = database.OpenView(sql);
view.Execute();
var record = view.Fetch();
if (record)
{
while (record)
{
WScript.StdOut.Write("Found: " + record.StringData(0) + ", " + record.StringData(1) + ", " + record.StringData(2));
if (record.IntegerData(2) != sequence)
{
WScript.StdOut.WriteLine(" - changing to " + sequence);
record.IntegerData(2) = sequence;
view.Modify(msiViewModifyUpdate,record);
}
else
WScript.StdOut.WriteLine(" - OK");
record = view.Fetch();
}
view.Close();
database.Commit();
}
else
{
view.Close();
throw("Warning - Could not find " + table + "." + action);
}
}
catch(e)
{
WScript.StdErr.WriteLine(e);
WScript.Quit(1);
}
To call this script to perform the change to the action sequence mentioned above you would put the following in a batch file and call that from the post build event e.g. PostBuildEvent = $(ProjectDir)PostBuild.bat
cscript.exe MSI_SetActionSequence.js YOURINSTALLER.MSI InstallExecuteSequence RemoveExistingProducts 1525
Some notes to others out there. I had the "Error 1001. The specified service already exists" problem, and tried the above and it didn't seem to work. Here's what I ran into:
* Make sure the RemovePreviousVersions property on your installer project is set to True. This seems obvious--obvious, that is, if you know about it. By default it is set to False. If False, the above procedure will not solve your problem. *
I have some assemblies installed in the GAC. It appears that when I moved the RemoveExistingProducts sequence that these files were removed from the GAC, but not reinstalled. To solve this I installed all assemblies in the Application Folder. FYI, I'm using VS2010.
Also, another nit-pick. If a user selects "Repair" when attempting to reinstall the same version of a product, they will still get "The specified service already exists" error. If I get time I'll try to fix this. If someone else out there knows how to fix it, could you post?
All that said, thanks for posting this!
The solution provided by Ryan addresses part of the issue I am facing. It does perform full uninstall, followed by install.
However, I have another issue, in my case some of the programs are running in the background. Before the installer can run, the installer complains that some of the files are in use. And gives standard dialog box asking for either to close the application, or restart to complete updating.
Is there a way, eg. a custom action or a setting, to kill the processes running in the background so that the installer goes smoothly?
