CListBox::ResetContent[^].
Btw there's also a fundamantal flaw in your method. Consider what your loop does:
1. i becomes 0, the very first ("zeroth") item is deleted from your list, this will raise all other items 1 place, so 0 goes away, 1st becomes the 0th, 2nd becomes 1st, 3rd becomes 2nd and so on...
2. i now becomes 1, the 1st item in your list is deleted, and the ones under it jump up one place, so the 0th item is untouched, the 1st is deleted, 2nd becomes 1st, 3->2, 4->3 ...
3. i now becomes 2, 2nd item is deleted, so 0th is untouched, 1st is untouched, 2nd is deleted, 3rd becomes 2bd, 4->3 and so on...

Get the problem?

Yourwelcome. Smile | :)

If you want to stick to the for loop, try movings in reverse, so something like:

for (int I = Count - 1; I >= 0; I--)
  listbox.DeleteString(I);

or simply do this:

for (int I = 0; I < Count; I++)
  listbox.DeleteString(0);

You probably don't have the platform SDK installed on one of the machine. I don't know if it still the case for VC2008, but for VC2005, if you downloaded the free version, you had to download yourself the platform SDK (the platform SDK contains all win32 core functionalities).

In that case, have a look at the C++ project directories (Tools->Options->Projects and Solutions->VC++ Directories) and check that the Windows SDK include directory is in your include path.

these 4 directories are present over there

$(VCInstallDir)include
$(VCInstallDir)atlmfc\include
$(WindowsSdkDir)\include
$(FrameworkSDKDir)include

Mmmmm - $(WindowsSdkDir)\include is the one that contains WinUser.h, which contains SetDlgItemText (well, actually SetDlgItemTextA and SetDlgItemTextW).

Soooo - guess the first thing you could try is cleaning your build and rebuilding it (maybe the pre-compiled header's got itself confused?), then the next thing you could try is running your .cpp file that doesn't compile through the C pre-processor (use cl -P or set the relevant options in your project settings) on your machine and also a machine where it does build and check for differences between the pre-processor output - the definition of SetDlgItemText obviously isn't getting through the pre-processor to the compiler.

I seem to remember running into this a few years ago, but I don't remember the specifics.

Have you googled it? My guess is that you haven't.

EDIT - It may have had something to do with the CFormView...

Getting child windows handle

Hi There.

I have a Dialog based Application: Title "ABC Application"

I want to launch this appiication and then want to set an edit box available on this window with some text.
This is what I am doing right now.

ShellExecute(NULL, L"open", L"C:\\Program Files\\ABC.exe", NULL, NULL, SW_SHOWNORMAL);


HWND WndOST2PST = NULL;
WndOST2PST = ::FindWindow(NULL,L"ABC Application");


if(WndOST2PST == NULL)
      return false;


//Need to get handle for child windows



//SetWindowText(WndOST2PST, L"Pankaj");

SendMessage(WndOST2PST, WM_DESTROY, 0, 0);

I am not able to get handle of that specific edit control. Please provide some pointers for the same.

Thanks
PanB

hi,you'd better get the window handle from one variable.
the dialog title may be not right in this course.

Try this

CString Text;
CWnd *pWnd = FindWindow(NULL, "Title");
CWnd *pChildWnd = pWnd->GetWindow(GW_CHILD);
while(pChildWnd) 
	{
	   UINT uiID = pChildWnd->GetDlgCtrlID();
	   pChildWnd->GetDlgItemText(uiID, Text);// To get caption
	   pChildWnd->SetDlgItemText(uiID, "Test");  //To set value into edit box
	
	   pWnd->SendMessage(WM_COMMAND, MAKEWPARAM(uiID, BN_CLICKED), (LPARAM)pChildWnd->m_hWnd);// To click on the control
	   pChildWnd = pChildWnd->GetWindow(GW_HWNDNEXT);
	}

Use this to set data into text box

SendMessage(_Edithwnd, WM_SETTEXT, 0, (LPARAM)strCaption);

Hello to all,

i need to read a RTF file via iostream and convert it internally into plain text. The plain text should be searched for some keywords ... and the text between these keywords should be stored into an other (different) file.

The problem is not to read the RTF via iostream.

The problem is to skip all these formatting instructions of the RTF, because i need only the plain text.

Solving that, i need some code snippet ... but i haven't found something like that.

Additionally, the code should not use COM, DCOM, Automation of MS Word or somthing like that. Just a peace of C++ code.

Anybody out there ... having an idea how-to or look-where ???

Thank's for any idea.

Problem in Images display on dialog.

Hi,

In my application I am having dialog .I am receiving images from mobile and I am displaying Images on dialog. I have added vertical scroll bar to dialog.I am creating 8 static controls programatically on dialog and I am using these 8 static controls for Image display. At a time I am displaying 8 Images on Dialog.I am using Scroll bar to display all Images. I have written following code in my "displayImage" function.for every scroll I am calling this function.

for(int i = 0; i < 8; i++)
	{
		//To get 4 Images for each row
		if((i != 0)&&(i%4 == 0))
		{
			x1 = 1;
			x2 = 250;
			y1 = y1+355;
			y2 = y2+355;
		}
		
		//Static control creation for Image
		myStatic[i] = new CStatic();

		myStatic[i]->Create(_T(""),WS_CHILD|WS_VISIBLE|SS_BITMAP,
CRect(x1,y1,x2,y2),this);  
image.Load(Image);
		HBITMAP hbmp = image.Detach();
		if(hbmp == NULL)
		{		
			Error = GetLastError();
		}
                if(hbmp != NULL)
		myStatic[i]->SetBitmap(hbmp); 
}

First 8 Images are displaying Properly.After that If I scroll Scroll Bar dialog is showing first 8 Images first and It is displaying second 8 images.If I scroll third time it is showing first 16 images after that it is showing third 8 images and so on.Can anyone help me.

Probably your data structure is not getting cleared and still holds the images that you displayed earlier. Debug to check

You need to google first, if you have "It's urgent please" mentioned in your question.

I am facing this issue since few days. I tried so many options but no use

1)I deleted myStatic[i] variables after using static controls.
If I do that dialog is not showing any Images.here myStatic is local variable.

2) I declared member variables m_myStatic[8].No use.

Of course you delete the static control variables. But where and how do you store the images that later on get displayed in these static controls. My previous question was whether you clear the data from the structure and not the static controls themselves.

You need to google first, if you have "It's urgent please" mentioned in your question.
