I have used implib32.exe to convert an ocx to Lib file.The lib file gets generated but when I am trying to link it ,it gives a linking error for the lib functions.
Plz suggest a way to do the conversion.

I do not think you can use implib32 to just convert an activeX ocx to be functioning as a native dll.
From this URL.
It said what implib32 does is
DUMPBIN to create a file
which lists all exports of a DLL, reformat this file to .DEF-file using a
text editor and then use LIB to create a import library from the .DEF-file.
The ocx need to be registered with regsvr32 which basically register itself to the registry in order to be functioning and native DLL does not require that.
(or if you are doing some sort of hacking here, then that is another case)

I have installed Visual C++.NET and Visual SourceSafe 6.0 Netsetup, but Visual SourceSafe is still not available in the Visual C++ Add-In menu. Why?
I have downloaded the latest service pack (SP6) for SourceSafe, but nothing happened.
With VC++ 6.0 everything works well.
Pleeeeease help!

The source safe menu is at File - Source Control. No longer at the same place as in VC6.
Hope this helpful.

I have no Source Control menu item in File menu in VC.NET.
If I open a project (dsp or dsw) with VC6, I have to type my VSS password. And there menu items for source control (check in/check out etc. )in File View. If I type something in a source file, I am asked automatically whether I want to check it out.
VC.NET opens it without asking anything. And there are no add-ins Solution Explorer. If I type something in a source file, the editor signs that the files are read only, but nothing else.

When you are starting a blank project. You should be able to see the source control menu at the menu. (well, at least for mine)
If it doesn't. Probably it is something to do with your installation.

Visual SourceSafe 6.0 doesn't integrate with Visual C++ .NET
You need Visual Studio .NET (C++, C# and that other one), it comes with a new Sourcesafe version.
You can keep working with version 6 though as a standalone apllication

Hi,
I tried to compile the native C++ program in C++ .NET command line Tool.
When i compiled Managed C++ is run without any warning. When i compiled both
Managed and unmanaged code in single file is run without any extra warning.
But, when i try to run native C++ only i got so many warnings.
I got the following warning. So, what swicth can i use to compile native C++
alone.

Hello!
I have 3 problems with CListCtrl in LVS_ICON mode.
1. I have 2 button click handlers:
CMyDlg::OnButton1()
{
m_ctrlList.InsertItem(0, "Item1", 0);
m_ctrlList.InsertItem(1, "Item2", 1);
m_ctrlList.InsertItem(0, "Item0", 3);
}
CMyDlg::OnButton2()
{
m_ctrlList.InsertItem(0, "NewItem1", 0);
m_ctrlList.InsertItem(1, "NewItem2", 1);
m_ctrlList.InsertItem(0, "NewItem0", 3);
}
After the first click the list is:
"Item0, Item1, Item2"
All right!
But after the second click the list is:
"Item0, Item1, Item2, NewItem0, NewItem1, NewItem2"
Why NewItem0 that was inserted in position 0 is actualy appears in position 3? Looks like session wrighting on CD-R  Then how ListControl determines the begining of the new "session"?
2. I use SetIconSpacing function and ListControl sometimes draws selection incorrectly: a part of icon image is not painted by selection color. When selection is changing some other painting errors are happening.
3. Is there any way to force ListControl to paint all item label's text, not only first 2 lines and "..."?

The items are probably being sorted as they are inserted.

Hi guys
I'm trying to do the following
I want that when I save a document and change it, if I click in my recent saved document name, recover the old one.
Now when I click in the most recent used file (the recently saved) it does nothing.
Example
I save my document as "TEST"
I modify within the program the TEST document (but don't SAVE)
I clic in TEST (MostRecentUsed files) --->NOTHING HAPPENS
What I want --->Load the saved document.
Thanks in forwarding
Doc

By definition, that is not how a default MDI application works. You'll need to override the OpenDocumentFile() method to change the default behavior.

I need to appear message before closing form application..

If you are using MFC, you can use the OnClose function.

Hi all,
I was able to display an raw image (8bit per pixel) using StretchDIBits method. However, my OnPaint() is called alot so the image is flickering like crazy. How can I get rid of this flickering business. I've read tutorials on double buffering, however, I still don't understand how to apply it to this case where the image is from an array of bytes.
Thanks,
|
|

First store your Image in MemoryDC.
then call Invalidaterect();
You will get code in KRUGLANSKI.
|
|
|
|

If the window flickers it must mean that something else is being drawn to it between each of your StretchDIBits calls (otherwise you'd just be blitting the same image over the top of itself and you'd see no flicker).
Probably what's causing the flicker is that your window's background is being erased as part of the repaint. However, if your image fills the window this erasing is entirely unnecessary and you should prevent it.
An easy way to do this is to trap the WM_ERASEBKGND message and return zero -you should then find that that flickering goes away.

Hi,
I have tried to override OnEraseBkgnd, the problem still occurs. I am writing and ViewLCD application for a camera (just like a digital camera with an LCD at the back to view the scene that the camera is pointing to).
Thanks,
|
|
|
|
|
Well, the flicker will only appear if something other than your bitmap is being drawn between your updates - the obvious candidate is erasing the backrgound but is there anything else in your WM_PAINT processing that might be causing this?

This is all in my OnPaint() of a CChildView:
CPaintDC dc(this); // device context for painting
CDC* pDC = &dc; // Convert to context device pointer
HDC hdc = pDC->GetSafeHdc();
// Prepare Header for image
BITMAPINFO *m_pBitmapInfo;
m_pBitmapInfo = (BITMAPINFO*)new char[sizeof(BITMAPINFO) + sizeof(RGBQUAD)*256];
// Load header
m_pBitmapInfo->bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
m_pBitmapInfo->bmiHeader.biWidth = ImX;
m_pBitmapInfo->bmiHeader.biHeight = -ImY;
m_pBitmapInfo->bmiHeader.biPlanes = 1;
m_pBitmapInfo->bmiHeader.biBitCount = 8;
m_pBitmapInfo->bmiHeader.biCompression = BI_RGB;
m_pBitmapInfo->bmiHeader.biSizeImage = 0;
m_pBitmapInfo->bmiHeader.biXPelsPerMeter = 0;
m_pBitmapInfo->bmiHeader.biYPelsPerMeter = 0;
m_pBitmapInfo->bmiHeader.biClrUsed = 256;
m_pBitmapInfo->bmiHeader.biClrImportant = 0;
int i;
for ( i = 0; i < 256; i++ )
{
m_pBitmapInfo->bmiColors[i].rgbBlue = i;
m_pBitmapInfo->bmiColors[i].rgbGreen = i;
m_pBitmapInfo->bmiColors[i].rgbRed = i;
m_pBitmapInfo->bmiColors[i].rgbReserved = 0;
}
// Stretch pixels out to screen
StretchDIBits(hdc,
xCord,yCord,ImX,ImY,
0,0,ImX,ImY,
img, //------->>> Pointer to array of bits, a CChildView variable member.
m_pBitmapInfo,
DIB_RGB_COLORS,
SRCCOPY);

Looks OK to me, although I'd set up the BitmapInfo record outside the paint processing. If ImX, ImY change between calls you can set just them. This would get that nasty for loop out of there!
Anyhow, back to the flicker - the other possibility is that your WindowClass (that's class as in WNDCLASSEX) has a background brush defined. In this case I seem to recall that BeginPaint will erase the background without raising a WM_ERASEBKGND message.

hii...
how can i get a bitmap from a window and use it in my application?

Hello,
I am working with win32 serial communication in VC++. My application communicates with a Control Panel hardware device which is similar to a Keyboard. It has various keys/buttons (”0-9 digit keys, A-Y alphabet keys and F1,F2,F3 keys”) on it , and is connected through the serial port of the PC. My application has to capture which key/button is pressed and released on the Control Panel board. When a key/button is pressed or released on the Control Panel board, my application should post the appropriate message to the main handling application which is responsible for processing the Key Down and Key Up messages received from Control Panel board.
My application can find out the keys pressed or released on the Control Panel board. Now I need to post WM_KEYDOWN and WM_KEYUP messages when keys are pressed or released to the handling main application. But I should find a way to tell the handling main application, that the posted WM_KEYUP or WM_KEYDOWN message is from the Control Panel board and not from the Key board. The handling main application should be able to distinguish between the WM_KEYDOWN and WM_KEYUP messages from the Keyboard and the Control Panel board.
When I went through the MSDN,
http://msdn.microsoft.com/library/d.../wm_keydown.asp
I found that there is a field “Scan Code” in the lParam which is of use. I want to use this field to differentiate between messages of control panel buttons and keyboard keys.
But I need some more information on this:
1. Are scan codes for keyboards standardized?
2. If scan codes are standardized, where can I get a list of the unused scan code range so that I may use them for the control panel?
3. How can I set these scan codes while posting the messages trough code?
I am trying to search on google.com site for this information, but couldn’t get any useful link. I have never worked with this type of application and hence am unable to proceed further.
Can anyone please help me in this? It would be of great help to me if you can give me some links or information on this area?
Thanks in anticipation of information.
Madhavi.

Why are you using WM_KEYUP and WM_KEYDOWN? If you want to distinguish your keys from those from the system why not just use messages such as:
#define WM_CONTROLPANEL_KEYUP WM_APP+0
#define WM_CONTROLPANEL_KEYDOWN WM_APP+1
