The xmldom usage in the package is as follows. I specify the next line to be added. But I can't find a solution on how to convert the line to xmldom format and add it.
vc_xml := '<'||cs_KEY_TAG||'>'|| pin_xml ||'</'||cs_KEY_TAG||'>';
parser := xmlparser.newParser;
xmlparser.parseclob(parser, vc_xml);
doc := xmlparser.getDocument(parser);
nl1 := xmldom.getElementsByTagName(doc, cs_KEY_TAG);
node := xmldom.item(nl1, 0);
nl2 := XMLDOM.getchildnodes(node);
len1 := xmldom.getLength(nl2);
FOR i in 0..len1-1 LOOP
node := xmldom.item(nl2, i);
nl3 := xmldom.getchildnodes(node);
len2 := xmldom.getLength(nl3);
FOR j in 0..len2 -1 LOOP
node := xmldom.item(nl3, j);
element := xmldom.makeElement(node);
node := xmldom.getFirstChild(node);
'<device_count>' || vs_d_count || '</device_count>' ->this is the line to add to the XML
I am trying to create a structure:
MyTopic
TopicID : String;
HelpID : Integer;
I wanted to create an array of these structures so I could sort them.
I have tried using this type / record syntax but it is failing.
Update
I defined this type and procedure:
type
TMyTopicRecord = record
idTopic : String;
idContextHelp : integer;
End;
procedure GetSortedTopicIDs(aTopics : array of String; size : Integer);
var
aMyTopicRecords : array of TMyTopicRecord;
temp : TMyTopicRecord;
iTopic, i, j : Integer;
begin
// Init the array
SetLength(aMyTopicRecords, size);
// Fill the array with the existing topid ids.
// Get the context ids at the same time.
for iTopic := 0 to size - 1 do
aMyTopicRecords[iTopic].idTopic := aTopics[iTopic];
aMyTopicRecords[iTopic].idContextHelp := HndTopics.GetTopicHelpContext(aTopics[iTopic]);
// Sort the array on context id
for i := size-1 DownTo 1 do
for j := 2 to i do
if (aMyTopicRecords[j-1].idContextHelp > aMyTopicRecords[j].idContextHelp) Then
begin
temp := aMyTopicRecords[j-1];
aMyTopicRecords[j-1] := aMyTopicRecords[j];
aMyTopicRecords[j] := temp;
end;
// Rebuild the original array of topic ids
for iTopic := 0 to size - 1 do
aTopics[iTopic] := aMyTopicRecords[iTopic].idTopic;
end;
The procedure gets called in a loop of the parent function (code snipped):
function GetKeywordsAsHtml(): string;
var
aKeywordList: THndKeywordsInfoArray;
aAssociatedTopics: array of string;
nBlocLevel, nDif, nClose, nCurKeywordLevel, nCurKeywordChildrenCnt: Integer;
nCurKeyword, nCurKeywordTopic: Integer;
nCountAssociatedTopics: Integer;
sCurrentKeyword, sKeywordLink, sKeywordRelated: string;
sKeywordJsCaption: string;
begin
Result := '<ul>';
nBlocLevel := 0;
try
aKeywordList := HndKeywords.GetKeywordList(False);
for nCurKeyword := 0 to length(aKeywordList) - 1 do
begin
sCurrentKeyword := aKeywordList[nCurKeyword].id;
nCurKeywordLevel := HndKeywords.GetKeywordLevel(sCurrentKeyword);
nCurKeywordChildrenCnt := HndKeywords.GetKeywordDirectChildrenCount(sCurrentKeyword);
sKeywordLink := '#';
sKeywordRelated := '[]';
aAssociatedTopics := HndTopicsKeywords.GetTopicsAssociatedWithKeyword(sCurrentKeyword);
nCountAssociatedTopics := Length(aAssociatedTopics);
if nCountAssociatedTopics > 0 then
begin
GetSortedTopicIDs(aAssociatedTopics, nCountAssociatedTopics);
// Code snipped
end;
end;
finally
Result := Result + '</ul>';
end;
end;
The script compiled in the HelpNDoc internal editor with no issues. But when I go to actually build my HTML documentation I encounter a problem:
The HelpNDoc API is explained here.
Is there something wrong with my code?
I decided to go about it a different way and used a simpler technique:
procedure GetSortedTopicIDs(var aTopics : array of String; iNumTopics : Integer);
var
iTopic : Integer;
// List of output
aList: TStringList;
begin
// Init list
aList := TStringList.Create;
// Build a new array of "nnn x"
// - nnn is the help context id
// - x is the topid id
// Note: I know that the context ID values are within the range 0 - 200
for iTopic := 0 to iNumTopics - 1 do
// We pad the context id with 0. We could increase the padding width to
// make the script mre useful
aList.Add(Format('%0.3d %s', [
HndTopics.GetTopicHelpContext(aTopics[iTopic]),
aTopics[iTopic]
]));
// Now we sort the new array (which basically sorts it by context id)
aList.Sort;
// Update original array
for iTopic := 0 to iNumTopics - 1 do
// We ignore the "nnn " part of the string to get just the topic id
aTopics[iTopic] := copy(aList[iTopic],5, length(aList[iTopic])-4);
// Tidy up
aList.Free;
end;
This compiles and I get the sorted array of topic IDs at the end of it. So the pop-up help is now listed as I want.
I have this:
ShellExecute(Application.Handle, nil, PWideChar('explorer.exe'), PWideChar(ImagesDir), nil, SW_SHOWNORMAL);
where the variable ImagesDir is the directory of Images that I want to show by the Windows Explorer...
How can I run the Windows Explorer beside my application at a specified Bounds, for exemple like this?
when you open any File Explorer window (such as going to C:\ ), File Explorer has a specific saved window size that it opens with. So when you resize it, either horizontally and/or vertically, close it and re-open it again, it saves the size of the window, and the location within the Registry where this information is saved is this:
On my system, HKCU\Software\Classes\Local Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell\WinPos1366x768x96(1)..position, where position is left, right, top or bottom, gives the position of the window border in pixels.
I assume the name of the key depends on the screen resolution.here
and the code will be like that:
.....
const
AMainKey = '\Software\Classes\Local
Settings\Software\Microsoft\Windows\Shell\Bags\AllFolders\Shell\';

the Result here
You can use the following function to open an explorer window and have it point to a specific directory.
USES Windows,ShellAPI;
FUNCTION ExploreDirectory(CONST Dir : STRING) : BOOLEAN;
BEGIN
Result:=(ShellExecute(GetDesktopWindow,'open',PChar(Dir),'','',SW_SHOW)>32)
END;
Note, however, that you can't (with this code) make the Explorer window "follow" your program, ie. the opened window is a completely autonomous window that has no link to your program, just as if the user had browsed to the directory himself. If you call this function again with a new directory, Explorer will open a new window with that directory (and keep the old one opened).
UPDATE:
If you want to be able to manipulate the explorer window after it is opened, you need to use the various interfaces that Explorer exposes. I have made a UNIT that allows you to do what you seek as well as returning the interface needed to be able to manipulate the window afterwards. It is heavily based on the code found in this answer:

It is made for use with Delphi Tokyo 10.2.3 so if you use an earlier version (you didn't specify Delphi version in your question), you may need to adapt the USES list to match.
I use this example to send a string between two applications.
When I press the Send button for the first time, the string is sent to the Receiver, but only a part of the string is received.
When I press the Send button for the second time, I get "Window not found!".
The window is right there on screen. Why it works when I press the button the first time, but not the second time?
This is the sender:
procedure TfrmSender.SendString;
var
stringToSend : string;
copyDataStruct : TCopyDataStruct;
begin
Caption:= 'Sending';
stringToSend := 'About - Delphi - Programming';
copyDataStruct.dwData := 12821676; //use it to identify the message contents
copyDataStruct.cbData := 1 + Length(stringToSend) ;
copyDataStruct.lpData := PChar(stringToSend);
SendData(copyDataStruct) ;
end;
procedure TfrmSender.SendData(CONST copyDataStruct: TCopyDataStruct);
VAR
receiverHandle : THandle;
res : integer;
begin
receiverHandle := FindWindow(PChar('TfrmReceiver'), PChar('frmReceiver')) ;
if receiverHandle = 0 then
begin
Caption:= 'Receiver window NOT found!';
EXIT;
end;
res:= SendMessage(receiverHandle, WM_COPYDATA, Integer(Handle), Integer(#copyDataStruct));
if res= 0 then Caption:= 'Receiver window found but msg not hand';
end;
And this is the receiver:
procedure TfrmReceiver.WMCopyData(var Msg: TWMCopyData);
VAR
s : string;
begin
if Msg.CopyDataStruct.dwData = 12821676 then
begin
s := PChar(Msg.CopyDataStruct.lpData);
msg.Result := 2006; //Send something back
Winapi.Windows.Beep(800, 300);
Caption:= s;
end
end;
To summarize the comments there are two errors
1) (See #Tom Brunberg) is that the length is set incorrectly which is why you only get part (about half? of the string)
It should be
copyDataStruct.cbData := sizeof( Char )*(Length(stringToSend) + 1 );
2) The forms caption is being changed which invalidates the expression
FindWindow(PChar('TfrmReceiver'), PChar('frmReceiver'))
because the second parameter is the form's caption (in Delphi terminology)

Compiles fine, retrieve correctly sql machine and instance using the right password but whenever running the installer, at a moment the setup aborts providing message "Microsoft OLE DB Provider for SQL Server: Could not find store procedure 'ÿƥS'.

Problem occurs in the if(LoadStringFromFile(ExpandConstant('{app}\script.sql'), Myscript)) statement because the sql file was not ANSI coded.
Everything gone fine by changing the coding.
thanks everybody!
