I am in the process of making a simple image viewer in VB.NET. I want to be able to open an image with my application. How does VB.NET receive the URL of the file that the user is trying to open?
Seems simple but without knowing key terms, my Google searches are returning completely the wrong things!
You want to inspect the Environment.CommandLine Property
This property provides access to the program name and any arguments specified on the command line when the current process was started.
The program name can include path information, but is not required to do so. Use the GetCommandLineArgs method to retrieve the command-line information parsed and stored in an array of strings.

I am a using webpage with method. In the html form i have used POST method which is calling an RPGLE program and by using CGI libraries i am retrieving the values in my RPGLE program. Once i retrieve the value in program i want to show the same page again but after removing the entered value on the form page.
I am trying to use getHtmlIfs() location method to read the same IFS file and then using wrtsection('*fini') as i haven't specified any tag in html. but it is giving me internal server error.
i tried to use tag and write it as well but still the same result.
please advise.
I assume you're using the CGIDEV2 package.
You say you write *fini, but are you writing an actual record first?
Check the joblog for the CGI job (they run in QHTTPSVR subsystem by default).
Check the CGIDEBUG table in your CGI library.
I am currently trying to extract property values from my properties file, but am running into some problems. I can't test this in ML query console, because the properties file doesn't exist there. I am currently trying to grab the values of the file like this
let $port := #{#properties["ml.properties-name"]}
I've also looked at
xdmp:document-get-properties(
$uri as xs:string,
$property as xs:QName
however that is limited to .xml files I believe. Does anyone have a way/work-around of accessing these values? I can't seem to find one I've looked at some documentation on Marklogic's website, but can't seem to get anything to work. The way I was accessing before was in ruby, through monkey-patching allowing me to access those private fields.The problem with that is the ruby script I call is only called once, while my .xqy file is ran every minute that sends args to another function. I need to access those args from the properties file, right now I just have them hard-coded in. Any thoughts?
Thanks
You cannot access deployment properties like that, but you can pass them along with deployment. If you create a new REST app with latest Roxy, you should get a copy of this config.xqy added to src/config/:
https://github.com/marklogic-community/roxy/blob/master/deploy/sample/custom-config.xqy
That file is treated specially when deployed to the modules database. Properties references are replaced inside there. In your case, add another variable, and give it a string value following the #ml.xyz pattern:
declare variable $c:port := "#ml.property-name";
You can then import the config lib, and use it in your code.
These so-called Deployer Substitutions are described in more detail on the Roxy wiki:

I have an application written in VB.NET and I have a file association that will trigger a specific function if opened from that file type.
The only thing is that If the application is already open and a user clicks on an associated file, it opens another instance of the application.
Basically, I would like to have the currently running instance of the application handle any incoming arguments from a double click on an associated file. Here is some pseudo-code to help understand.
if(application.isAlreadyRunning){
application.doSomething(filePath);
}
else{
proceed normally...
}
I've looked into mutexes, and they allow me to ensure that only one instance of the app is running, but then I need to pass the filename to the currently running instance.
Thanks!
P.S. I forgot to mention that I am using ClickOnce to deploy the app and AppDomain.CurrentDomain.SetupInformation.ActivationArguments.ActivationData to retrieve the "arguments"
I am doing a website on YII and PostgreSQL. It is recurrently exiting inside $model->validate() method by printing 'test'. I have searched whole code, There is no exit code on controller , model, beforeValidate(), afterValidate(), even whole project.
Question
How can i debug on such scenario. I have only access to ftp, Netbean as IDE, but no localhost. How to find which file is printing exit code or do you have any idea ?
Thank you,
Ram
Messages can be logged by calling either Yii::log or Yii::trace. The difference between these two methods is that the latter logs a message only when the application is in debug mode.
Yii::log($message, $level, $category);
Yii::trace($message, $category);
When logging a message, we need to specify its category and level. Category is a string in the format of xxx.yyy.zzz which resembles to the path alias. For example, if a message is logged in CController, we may use the category system.web.CController. Message level should be one of the following values:

Hey Overflow, I have an application which serves as a user interface for a spartan/command line program.
I have the program running on a separate process, and my application monitors it to see if it is responding and how mush CPU it is utilising.
Now I have a list of files in my program (listbox) which are to be sent to the application, which happens fine. But I want to be able to read text from the com-line so as to determine when the first file has been processed.
Com-line says one of "selecting settings", "unsupported format" and "cannot be fixed".
What I want to be able to do is when it says one of these three things, remove item(0) in listbox1.
Is this possible?
I thought of programming an event which handles com_exe.print or something or other, if possible.
Read the standard output from the process.
MSDN Article
Theres an example of synchronous reading from the process in that article.
You might be able to do what you want using the AttachConsole API function as described here. However, maybe an easier alternative would be if you could pipe the output of the command line app to a text file and then your app could just parse the text file (assuming that the command line file wouldn't lock the file completely, I'm not sure about that).
If you don't know how to pipe the output, this page has quite a bit of information.
