I coded like this:
#pragma data_seg("Shared")
HWND g_hWndCaller = NULL;
HHOOK g_hHook = NULL;
#pragma data_seg()
#pragma comment(linker, "/SECTION:Shared, RWS")
but it does not work, why?

Do MSDN articles Q100634 or Q125677 help?

Just in case it is sotehing as STUPID as this..
I notice the documentation shows /INCLUDE, but the sample shows this:
#pragma comment(linker, "include:__mySymbol")
So, as a suggestion, why don't you try using all lowercase for the word 'section':
#pragma comment(linker, "/section:Shared, RWS")
Also, you might want to call your section something besides 'Shared' so you don't confuse the compiler or linker over another keyword. Use your company initialz in front of it or something..
#pragma data_seg("YCIShared")
HWND g_hWndCaller = NULL;
HHOOK g_hHook = NULL;
#pragma data_seg()
#pragma comment(linker, "/section:YCIShared, RWS")

There is no single function to do this. One way would be to use RegSaveKey() and RegRestoreKey(), but those only work on Windows NT 3.1 and later. Another way is to use a series of copy and delete calls.

All:
I have created a process using CreateProcess() with a NULL executable module and the STARTUPINFO specifies tha the window is to remain hidden (which works). The question is how do I send this 'new' process a message to show the console window which was hidden during startup?
STARTUPINFO Task_SI;
ZeroMemory(&Task_SI, sizeof(Task_SI));
Task_SI.wShowWindow=SW_HIDE;
Task_SI.dwFlags=STARTF_USESHOWWINDOW;
Task_SI.cb = sizeof(Task_SI);
PROCESS_INFORMATION Task_PI;
CreateProcess(
NULL,
CmdStr,
NULL,
NULL,
0,
CREATE_NEW_CONSOLE,
NULL,
NULL,
&Task_SI,
&Task_PI
);
After this process is initialized, a loop begins which checks to see if the process has completed and dispatches messages while waiting...
GetExitCodeProcess(Task_PI.hProcess, ExitCode);
while(*ExitCode==STILL_ACTIVE){
while(PeekMessage(&msg, NULL, 0, 0, PM_REMOVE))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
Sleep(100);
GetExitCodeProcess(Task_PI.hProcess, ExitCode);
}
After the process completed the usual cleanup occurs.
CloseHandle(Task_PI.hProcess);
CloseHandle(Task_PI.hThread);
How do I send this process a message to display itself (the console window)?
Thanks In advance,
Wallacebw

Hi all,
I am faced with the following problem. I should call the functions of a DLL (whose source code is not available), which doesn't seem to be implemented using Activex technology, and is downloadable in a package very "Visual Basic-oriented". In fact, the zip file contains only the dll binary and a .bas module, which looks much like the VB version of a C++ header file. Here's an excerpt of the .bas module:
<br />
Attribute VB_Name = "AstronomyFuncs"<br />
<br />
Declare Sub aa_hadec Lib "astro32" (ByVal lat As Double, ByVal Alt As Double, ByVal Az As Double, ByRef ha As Double, ByRef dec As Double)<br />
<br />
Declare Sub cal_mjd Lib "astro32" (ByVal mn As Long, ByVal dy As Double, ByVal yr As Long, ByRef mjd As Double)<br />
Now comes the question: despite there's is no provision for use within a Visual C++ program (no .h, .lib, etc.), anybody know how to overcome this problem, i.e. how to call the methods from C++?
Any help will be highly valued.
Regards,
Emmanuele

If you know the name of the function, you can dynamically load your dll and then get the adress of the function. Take a look at LoadLibrary and GetProcAddress in the MSDN for more informations

Hello All,
I have a requirement wherein have 2 sql server databases(say machine1 & machine2).
I want to run a sql query on machine1 , which would copy 5 tables in a 'XYZ' database on machine2 TO 'XYZ' database on machine1.
Note : I have user/password for both the machines.
I tried this using BCP utility, but problem using BCP is, exceptions cannot be handled And if there is a network failure during the process of data transfer , the process console window window of BCP utility, remains still(stuck) and needs user input to continue.
Please send me a QUERY(I already know about the Export/Import in SQL Server Enterprise Manager, but i need a query to run from vc++) to copy tables between 2 sql servers. that query, i should be able to place between BEGIN & COMMIT Transaction Process.
Waiting for ur reply.
Regards,
Prax.

It sounds like you want a SELECT INTO query.

In my vc++ application i have opened 2 CDatabase objects(dbtraget & dbSource). I want to copy database tables from dbSource to dbTarget , then how do i specify the the particular database in the "SELECT INTO..." query.
And where should i run this query, in
dbSource.ExecuteSQL(".....")
OR dbTraget.ExecuteSQL(".....")

Hi!
I’m about to pass a VARIANT to a “COM-function”.
In the API I says I should pass: an Array of VARIANTS.
How do I create the array.
I have looked at the function SafeArrayPutElement(…) and managed to pass an Array of BSTR… but I do need to pass it like an VARIANT Array….?
Tips?

Hi!
I'm going to code an application which uses the IrDA-devive of my PDA. Until now everything is going ok, but now i stuck at the question how to create specific frequencies and single pulses of a specific length. I've read in the source of win-lirc that pulses can be created by setting SETDTR & SETRTS, but it never worked at my application.
Hope that someone can help me with that
Thx a lot for all replies

Hi all,

Thanks

There should be a template for MFC app. or ATL app. Choose one of those and you will be presented with further options.

Hi guys,
Can anyone explain the differences between the following two calls:
UpdateWindow(hWnd);
and
InvalidateRect(hWnd, NULL, FALSE);
If I replace one with another, the app would be drawn differently. But I couldn't tell why by reading the MSDN docs 
Thanks alot
|
|
|
|
|
I think I sort of know now -
UpdateWindow(hWnd) only places a WM_PAINT message in the message queue, which leads to an execution of the WM_PAINT's message handler finally. If at that time the client area is all validated already, the window will not be re-painted.
On the other hand, InvalidateRect(hWnd, NULL, FALSE) explicitly invalidates the client area and then sends a WM_PAINT message. This makes sure the window will always be re-painted when the WM_PAINT message handler reaches its time. It does two things instead of just one.
Please correct me if I am wrong here.
Thanks
