I see you didn't have success. Too bad. Did you come across this article[^] when researching. It seems to suggest that it will work.

I happend to face the same problem. This solution seems to work, but you should keep in mind that it does nothing more but resetting some timers. So you need to create a timer event and invoke the function when the timer expires.
Thanks for this idea however!

how to make it in such a way that when i click a button, another document will open?
|
|
|
|

If you mean an MFC SDI application, you can't.
The SDI architecture has only one document, and it never closes. However, when you choose "File->New" (or in your case on a button click) the CDocument::ResetContent function is called.
You could handle that function in your document class as reset all your variables to their initial state, release any memory that you have allocated and such, essentially ending up with a new, empty document.
Hope that helps.

meaning i can only make it that when i click on a button, the whole layout can be changed but not pop up a new document?
|

Not sure what you mean "pop up a new document". The document is a behind the scenes container for your data - it is not visible. You see the data in the document in your View - that's the visible part.
In SDI you can only have one document, but you can have more than one view of the document. You can search for how to create different views and switch between them - that may be what you're looking for.
Good luck.

If you're using a data acquisition board, see if the manufacturer has a SDK...

It is almost certain that the manufacturer-provided drivers will implement DMA (assuming the board is capable of DMA of course.) The manufacturer wants his board to be as fast as possible.
So if you use the drivers to tell the board to get a few thousand samples into memory, the board's DMA controller will probably be used.

Hi,
I have a static library which is linked with a DLL, and I want to export the symbols from the DLL as well as the symbols in the static library so that the user of the library sees it as just a DLL with exported symbols.
Need for such a case:
I have to build a project in VC7 i.e VS .NET 2003. The target of the project is a DLL. The code is organized in small modules. Thus I want that these small modules get built separately and then when the main project builds, then all the modules get linked in and symbols properly exported in one .lib file and thus one single dll rather then having multiple lib files and multiple dlls.
I don't know how to do that in VS .NET
Thanks in advance,
any comments and suggestions are welcome,
Divick

Are there any limitations for using bitmaps on toolbar buttons?
On my main dialog window I have a toolbar with maybe 10 buttons, the bitmaps are loaded from a normal bitmap strip, each button 15x16, 4-bit color. This is displayed with no problems.
I have now added a toolbar to a child window, this time with bigger button (21x21), I have created it exactly the same way as the first. But the bitmaps are not being displayed correctly. White pixels are displayed as black, Black is displayed as gray, Green is transparent....
It's showing all the characteristics of picking the wrong color from the bitmaps color table. I first thought it was monochrome, but editing the bitmap proved me wrong. The only correctly displayed color is Blue, and I don't even want blue!!!
Any ideas????

Thaks for the reply, however I managed to fix it myself.
I was loading the bitmap from a resource file by passing the ID to the CreateToolbarEx() function. For some reason it wasn't being loaded correctly. Loading it myself with CreateMappedBitmap() solved the problem.

Hi waldermort,
This is a suggestion.
You can to make the function that create a bitmap file
then you can draw your bitmap on the created file.
Example:
I have 5 bitmapfile in the resource or disk
for 1 to n
BmpFile is CBitmap
BmpFile.Load-->From Resource
else
or you can create bitmap and return hBitmap that BmpFile.Attach(hBitmap)
then
img->Add(&BmpFile2,RGB(155,155,155));
m_wndToolBar.GetToolBarCtrl().SetImageList(img);
BmpFile.Detach

I use a CListCtrl object that, by default, should display Item No. 0 as selected. The Item ist displayed with a light grey background, when I click on an item is is displayed with a much darker background. How can I change the light grey to dark grey ?
m_Companies.SetItemState( 0, LVIS_SELECTED, <br />
LVIS_SELECTED | LVIS_FOCUSED);<br />
m_Companies.EnsureVisible( 0, FALSE);
|
|
|
|
|
if the item gets light gray but not dark gray, it means CListCtrl doesn't get focus.
use:
myList.SetFocus() to set focus on the CListCtrl.

Hello friends
I have developed a dialog based MFC application in which I did not show any dialog. My application show an icon in system tray only. Also my application runs on Windows 2000 Professional.
But when I open Task Manager it shows my application in process list as "myapp.exe"
I want to hide that from Task Manager.
Also I don't want to use any extra DLL file to do it.
How to do that?
Thankx in advance
Mahesh

Under windows 98 or earlier, a service will not be shown in Taskmanager by default. But under Windows 2000 or Above it is not possible to hide your process from taskmanager. It will be shown.

I need to find applications installed on Windows XP. Using HKEY_LOCAL_MACHINE\...\Uninstall does not work for the Office software (Word, Excel, Access...), unfortunately.
Does anybody know how to get such a list of applications like to be seen in the "Installed Apps Enumerator" Dialogbox of XP ?
I'd appreciate any code snippet in C/C++ which could help 
Best regards
Gerhard

windows keeps the list of installed application in that uninstall key that you mentioned and also in the MSI database.
You will have to query the MSI database for installed applications
