Hai all,
I still could'nt find the solution. I'm using win32 vc++ and subclass for drawing my button bagkground. ie.
BOOL CALLBACK DialogProc (HWND hDialog, UINT message, WPARAM wParam,
LPARAM lParam)
{

switch (message)
{
case WM_INITDIALOG:
{
lpfnOldWndProc1 = (WNDPROC)SetWindowLong( GetDlgItem (hDialog,IDSTART ) ,GWL_WNDPROC,(LONG)SubClassStartFunc);
.
.
.
EnableButtons(hDialog, IDSTART , false );
.
.
}

void EnableButtons(HWND hDialog,int DlgItemID, bool flag)
{
HDC hdc = GetDC(GetDlgItem(hDialog,DlgItemID);
.
.// to change my drawing...suppose to gray my text.
.
EnableWindow(GetDlgItem(hDialog,DlgItemID),flag);
}

LRESULT APIENTRY SubClassStartFunc(HWND hWnd,UINT uMsg,WPARAM wParam,LONG lParam)
{
switch(uMsg)
{
case WM_PAINT :
{
PAINTSTRUCT ps;
HDC hdc = BeginPaint(hWnd,&ps);
RECT rect;
GetClientRect(hWnd,&rect);
....//code for drawing background
SetBkMode(hdc,TRANSPARENT);
DrawText(hdc,"Start",5,&rect,DT_CENTER|DT_VCENTER|DT_SINGLELINE);
EndPaint(hWnd,&ps);
break;
}
}

The problem is I could'nt change my drawing in original dilaog proc. ie inside the func EnableButtons(...) whatever I do its not affecting the button drawing. How should I do ? Suppose I want to change the text color when i enable and disable botton. Whatever I do in this function is affecting the button itself and not the drawing. And I have given the button property as ownerdraw.
Pls someone help.

WM_PAINT is sent as soon as the button needs to be redrawn. You are calling DrawText yourself, but not handling and button disabling. Furthermore, if you have an ownerdrawn button, you are not supposed to handle WM_PAINT.

To be honest, you seem to have mixed up things here. It might be easier to make a complete custom class if you are going to handle WM_PAINT. For owner draw buttons, you handle WM_DRAWITEM in the parent. But in any case, if you are drawing the button yourself, you must also include drawing code for the different states.

Does it only stop automatically filling the password or does it also stop saving the password in the protected storage for later use if we choose to enable the option back?
Thanks.

I came across another article on this subject - http://pubs.logicalexpressions.com/Pub0009/LPMArticle.asp?ID=348

This article doesnt talk about DisablePAsswordCaching mentioned in the MSDN article, but says that the password is always saved at SPW and "To remember or not remember is controlled by more complex binary values hidden deep under the Protected Storage key.".

Can someone shed light as to what this author means here and how it is different from DisablePAsswordCaching?

Thanks.

how do you minimize or maximize a dialog from a menu?

Re: menu's

One way is to send the dialog a WM_SYSCOMMAND message.

UINT uCmdType = SC_MINIMIZE;  // SC_MAXIMIZE
PostMessage (WM_SYSCOMMAND, uCmdType);

System/CreateProcess'd process terminating

Hi Everyone,

I'm hooking a dos-based calculation engine("engine.exe") up to my GUI, and am having some problems. When I double click the engine.exe file, or run it from cmd it runs to completion and produces the correct output.

However when i attempt to run it from my program using either createprocess, or system(), it does not run and gives this output.

Abnormal program termination: Memory protection fault
CS:EIP = 01FFh:0000799Ch

I have swapped out the engine.exe path for several other programs, and they all work just fine from createprocess.

here is my createprocess line

fSuccess = CreateProcess((LPTSTR)ImageName,//Path + engine.exe
		(LPTSTR)CmdLine,// ""
		(LPSECURITY_ATTRIBUTES)NULL, 
		(LPSECURITY_ATTRIBUTES)NULL,
		(BOOL)TRUE,(DWORD)0,NULL,
		(LPTSTR)DirLine, // working dir
		(LPSTARTUPINFO)&SI,(LPPROCESS_INFORMATION)& pi);

and startupinfo

SI.cb =sizeof(STARTUPINFO);
SI.lpReserved = NULL;
SI.lpDesktop=NULL;
SI.lpTitle="EngineProcess";
SI.cbReserved2=0;
SI.lpReserved2=NULL;
SI.dwFlags = STARTF_USESHOWWINDOW;// enables SI.wShowWindow to work
SI.wShowWindow = SW_FORCEMINIMIZE;//hide the dow window

I'm just wondering if anyone has seen this before(unable to run dos-based programs from a VC++ program).

thanks,

Mike

I think you need to create a PIF file for the DOS program first? Never tried running a DOS app via CreateProcess(), though.

Also, look into the CREATE_NEW_CONSOLE for CreateProcess...

yeah, weirdest thing ...

It turns out that this problem only occurs when I launch my gui from the vc++ exclamation point (ctrl+F5)

when start the program by double-clicking the exe everything works exactly how it should.

Anybody know what extra options that exclamation-point button adds onto the executable?

thanks,

With CTRL+F5, the debugger is invoked, and the program runs within the debugger.

I have experienced this anomaly before, but I cant exactly be sure why it happens. And I have seen it happen in other compilers as well...

Setting The Current Directory

13-Jul-04 5:44

I have been using a TreeView to navigate through folders and when I double-click on a file then it will run.

I have problems with one particular file which I think is related to the current directory.

I was getting the directory from the TreeView (C:\MyFiles\Dir1), and using this in a call to

SetCurrentDirectory(CString item);

But will this work (I dont think it does) as usually you need to use strings such as C:\\MyFiles\\Dir1.

e.g. I use the following code to set the new current directory:-

currentDirectory = find.GetFilePath();<br />
currentDirectory = currentDirectory.GetBuffer(currentDirectory.GetLength ());<br />
strcpy(CurrentPathName, currentDirectory);<br />
SetCurrentDirectory(CurrentPathName);

I did get side-tracked as used

TCHAR CurrentPathName[] = "C:\\MyFiles\\Dir1";

Things works, but do I need to process the string and insert the extra '\' character?

ANy suggestions,

Sweep

String Escape characters are only used in literals. Once they are in memory escape characters have no significance and are processed as any other characters.

I am confused.

If I check the directory:-

//SetCurrentDirectory("C:\\CSL");<br />
TCHAR currentdir[255];<br />
GetCurrentDirectory(sizeof(currentdir), currentdir);<br />
ShellExecute(0, "open", m_strPath, NULL, NULL, SW_SHOWNORMAL);

Then its the director of my program, it has not changed. I did try and set it as I move through the folders (via the TreeView), but it seems not to have worked.

If I now do:-

SetCurrentDirectory("C:\\CSL");
ShellExecute(0, "open", m_strPath, NULL, NULL, SW_SHOWNORMAL);

The current directory has been set to C:\CSL and my ShellExecute command works as expected.

Question do I need to use TCHAR in some special way?

I believe we have a language barrier here, I have not idea what that means.

HINSTANCE ShellExecute(      
    HWND hwnd,
    LPCTSTR lpOperation,
    LPCTSTR lpFile,
    LPCTSTR lpParameters,
    LPCTSTR lpDirectory,
    INT nShowCmd
);

Try using the lpDirectory parameter of the function rather than changing directories, that's what it is for.

I am still confused!

In the DirTreeCtrl, I try and set the current directory to the on we have navigated to. (See code below)

if ( find.IsDirectory() && !find.IsDots() )<br />
{		<br />
	strDirArray.Add( find.GetFilePath() );<br />
	currentDirectory = find.GetFilePath();<br />
	currentDirectory = currentDirectory.GetBuffer(currentDirectory.GetLength ());<br />
	strcpy(CurrentPathName, currentDirectory);<br />
	SetCurrentDirectory(CurrentPathName);<br />
}

Now when I double-click a file in the current directory, the displayed current directory via AfxMessageBox is the one my program started up in. Not the one I thought I set in the code above.

void CScriptingDlg::OnNMDblclkTree1(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
	/* Now launch the CSL program with the selected file.	*/<br />
<br />
	//SetCurrentDirectory("C:\\CSL");<br />
	char currentdir[255];<br />
	CString messageStr;<br />
	GetCurrentDirectory(sizeof(currentdir), currentdir);<br />
	ShellExecute(0, "open", m_strPath, NULL, "C:\\CSL", SW_SHOWNORMAL);<br />
	messageStr.Format ("Current Directory = %s", currentdir);<br />
	AfxMessageBox(messageStr);<br />
}

If however I use palbano suggestion in the ShellExecute command and specify the directory the script file runs OK.

But the current directory is C:\MyProgram\res and not C:\CSL. This is want I dont understand.

Only if you are declaring the string as a constant, like you did here:

TCHAR CurrentPathName[] = "C:\\MyFiles\\Dir1";

Is 'find' a CFileFind object?

Yes,

CFileFind find;

Every time the directory changed I was trying to change the working directory:-

if ( find.IsDirectory() && !find.IsDots() )<br />
	{		<br />
          	strDirArray.Add( find.GetFilePath() );<br />
		currentDirectory = find.GetFilePath();<br />
		currentDirectory = currentDirectory.GetBuffer(currentDirectory.GetLength ());<br />
		strcpy(CurrentPathName, currentDirectory);<br />
		SetCurrentDirectory(CurrentPathName);<br />
	}
