Trying to get 4723 bytes of an oracle clob using ADO in vc++, when getting the recordset i am getting 4723 bytes but am getting 996 null chars after every good 996 chars.

Problem is occuring on a windows client against an oracle for linux server

Anyone have any clue why the data is getting corrupted via ado
If i use ole/db to get the data everything is fine. However this particular customer requires using ado recordsets

Any help is greatly appreciated

Making Static Control transparent

User 215597

26-Feb-04 18:07

Hi,
I have a main window in which I am displaying a bitmap using BitBlt in WM_PAINT.

In this window I have a 3 static controls.
I want to make them transperent ie: only their text appears.
I am using WM_CTLCOLORSTATIC for setting font and text color.

We need to return Brush from the WM_CTLCOLORSTATIC message...
I am using SetBkMode(hDC,TRANSPARENT)in this message and returning HOLLOW_BRUSH

Now in one of this static control I am changing its text using SetWindowText(...) frequently.
The problem is that all the text i m changing is looking all overlapped....
(I know this thing happens when one uses SS_SIMPLE style of static control ... I am not using this style)

what can be the problem.

Can anybody help me with this.

I just noticed Platform SDK: January 2004 Edition is available on Microsofts website. However, when I go to download it it just shows me the old SDK. Is it not available for download yet? I desperately need to get and even if I pay for it I still have to wait 2 weeks to get the CDs.

Any information?
Thanks

[Update]
I just went to order the CD and all I see available is the order SDK's, the new one is still not there!

Hai,
I am ving two icon handles, and want to combine them. So that one will be the overlay over the another. I tried with the following code, but it is not displaying properly. Any other solutions?

HICON CAutoDocuFileDlg::CombineIcons(HICON topIcon,HICON bottomIcon)
{// begin CombineIcons
ICONINFO newIcon;
newIcon.fIcon = true;
HDC screenDC = ::GetDC(NULL);
HDC iconDC = CreateCompatibleDC(screenDC);
HDC maskDC = CreateCompatibleDC(screenDC);
newIcon.hbmColor = CreateCompatibleBitmap(screenDC,16,16);
newIcon.hbmMask = CreateCompatibleBitmap(maskDC,16,16);
HGDIOBJ oldIconDC = ::SelectObject(iconDC,newIcon.hbmColor);
HGDIOBJ oldMaskDC = ::SelectObject(maskDC,newIcon.hbmMask);
BitBlt(iconDC,0,0,16,16,NULL,0,0,BLACKNESS);
BitBlt(maskDC,0,0,16,16,NULL,0,0,WHITENESS);

DrawIconEx(iconDC,0,0,topIcon,16,16,NULL,NULL,DI_
IMAGE);
BitBlt(iconDC,0,0,16,16,NULL,0,0,DSTINVERT); //
DrawIconEx(maskDC,0,0,topIcon,16,16,NULL,NULL,DI_
MASK);
DrawIconEx(iconDC,0,0,bottomIcon,16,16,NULL,NULL,
DI_NORMAL);
BitBlt(iconDC,0,0,16,16,NULL,0,0,DSTINVERT);
DrawIconEx(maskDC,0,0,bottomIcon,16,16,NULL,NULL,
DI_MASK);
BitBlt(maskDC,0,0,16,16,NULL,0,0,DSTINVERT);

::SelectObject(iconDC,oldIconDC);
::SelectObject(maskDC,oldMaskDC);
HICON newFileIcon = CreateIconIndirect(&newIcon);
::ReleaseDC(NULL,screenDC);
DeleteDC(maskDC);
DeleteDC(iconDC);
DeleteObject(newIcon.hbmColor);
DeleteObject(newIcon.hbmMask);
DeleteObject(oldIconDC);
DeleteObject(oldMaskDC);
return newFileIcon;
}// end CombineIcons

CMultiColumnComboBox Help

I recently added the .h and .cpp files from this link:

http://www.codeproject.com/combobox/mccombobox.asp

It says in the directions to add the line #include "MultiColumnComboBox.h" in the .cpp file, but then the visual studios won't recognize variables of this type in the .h file. Besides, the demo project on the link actually includes the library in the .h file of the class using it...so I did that. Now I'm getting a linker error for every function call that I try to make with the variables I declare of type CMultiColumnComboBox. The view classes I'm using these variables in are CFormView classes. Any ideas would be appreciated...Thanks a ton!

I can't for the life of me get 2 STATIC controls to use a white background instead of system COLOR_BTNFACE or whatever that color is.

Can someone give me the code required to change 2 named STATIC controls background color to white?

I have tried returning a white brush, but if I test the window handles to see if they match the STATIC controls inside OnCtlColor nothing happens??? Confused | :confused:

I'm lost and getting mad

Any help appreciated

Cheers

I stole this code form the MSDN article the last poster sent me...I ave no idea where m_brush comes from, but regardless the following ode doesn't work either....

I dunno if it's because I call SetDialogBkColor() in InitInstance or what, but this is pissin me off Smile | :)

HBRUSH hbr = CDragDialog::OnCtlColor(pDC, pWnd, nCtlColor);
	
// Are we painting the IDC_MYSTATIC control? We can use
// CWnd::GetDlgCtrlID() to perform the most efficient test.
if(pWnd->GetDlgCtrlID() == IDC_STATIC_ACCOUNT){
      
  // Set the text color to red
  //pDC->SetTextColor(RGB(255, 0, 0));

  // Set the background mode for text to transparent 
  pDC->SetBkMode(TRANSPARENT);

  // Return handle to our CBrush object
  //hbr = m_brush;
}

return hbr;

Thanks

You have to return a hbursh or the pdc settings is ignored,

the m_brush is a member variable of the dialog which is created during its initialization. you wanted to make the background white rite, so create a member variable of CBrush with RGB(255,255,255) and return this brush from the OnCtlColor method.

Odd memory leak cleans self upon window minimization

I have a memory leak in my Windows GUI program. When I go to my task manager I see the memory usage increasing by about 200k every second. I haven't been able to isolate it completely, but I notice that whenever I minimize the window, the memory usage jumps back to about 1070k and then restarts its slow ascent as it's minimized. Anybody have any idea what's happening? I have an OpenGL child window.

Hello Folks!

I've tried without success to put text and bitmap in the same line inside a RichEdit control. Until now I get only the bitmap or only the text. There's a way to do that (using MFC, or not) ?

Thanks for any reply.
