I write a simple dll and inject to another process, i communicate with the target process by sending message via a named pipe. But now, the problem is that, although i can retrieve a top-level window of the target process,i will get no response if i send menu messages to it(the hwnd i retrieved, using EnumWindows, no matter i send the messages in the callback functions of EnumWindows or not, the results are the same). So, i think, the hwnd handle i retrieved was not the target hwnd handle witch was responsible to such activity.
But, how could i get the right hwnd to handle these menu messages?
Thanks

i will get no response if i send menu messages to it(the hwnd i retrieved, using EnumWindows, no matter i send the messages in the callback functions of EnumWindows or not, the results are the same)
Can you please post some code lines (sending menu messages) ?

I wrote enumwindows callback function like following:
BOOL CALLBACK EnumWindowsProc(HWND hwnd, LPARAM lParam)
{
DWORD procId;
GetWindowThreadProcessId(hwnd,&procId);
log_message("Main window search callback function is called.");
if(procId==(DWORD)lParam){
....the message would to be send here
return FALSE;
}
return TRUE;
}
I send the menu message in two ways:
1. HMENU trayMenu = GetMenu(hwnd);
if(trayMenu!=NULL){//usually equal to NULL, and according to the failure in method 2(send msg no response) i think i got the wrong hwnd handle
HMENU subMenu = GetSubMenu(trayMenu,0);
if(subMenu!=NULL){
DWORD menuItemId=GetMenuItemID(subMenu,0);
if(menuItemId!=-1)
SendMessage(hwnd,WM_COMMAND,menuItemId,0);
}
}
2.Because i can get the menu resource id, and, this code is implemented in a injected dll to the target process, so, there is a second method here:
HMENU trayMenu = LoadMenu(GetModuleHandle(NULL),MAKEINTRESOURCE(IDM_MENU));
if(trayMenu!=NULL){//successfully always
...the other code looks the same with the method 1, but the target process's specified routine will not be actived, because its no response.

Try to find out whether you are retrieving ID of the right menu item. Call GetMenuString() for that item and debug print it. If you send the message for menu item which consists of submenu, that won't help you (application doesn't display out the submenu as a result).

im sorry to reply so latter. i have gone to another city. and i know them problem now, i got the right menu, menuitems and menuIDs, but sent the menu message to a wrong hwnd. The program has more than one toplevel hwnd, so, i retieve all its top level hwnds and send menu message it them. then, when i got the right hwnd, the message would send successfully.

Hi All,
I am using the Windows API to enumerate the certificate installed in the 'MY' store. In this process, i am able to enumerate the certificates installed in the smart card also. I am looking for an API which would differentiate whether the certificate is within the samrt card container or in the machine itself.
Your time and help will be appreciated. Thanks in advance.

Hello Frriends
"MSVCRT.lib(chkstk.obj) : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'"
This Linker error really frustrates me and i googling a lot but didnt find any relevant suggestion.Can Anybody suggests me here , how to overcome this error....
i am Trying to compile my project (that works fine for 32 bit) to make it compatible for 64-bit OS. For That I change the Setting as "Build -> Configuration Manager -> x64|Debug". I am using MS Vs2005(VC++)
...Sorry friends if ii make any silly mistake..
is there any other way to make a project 64 bit compatible.....

Do you have #include<iostream.h> in your code ? If yes, try #include<iostream> instead.

Thankx Malli!!
After Adding "iostream.h"
i got 42 errors as can u tell me what is it

I had asked to remove iostream.h include, and put <iostream> instead. Try that out. The other possibility is you are not able to link with msvcprtd.lib. Check whether the path for msvcprtd.lib is included into the project settings. Search for the lib, and make sure the paths are there in include directory.
Probably
\Program Files\Microsoft Visual Studio 8\VC\lib
\Program Files\Microsoft Platform SDK\ (SDK Folder)
for AMD64.
|

|

Seems you're application is targeted to run under 64-bit environment.
Please put $:\Program Files\Microsoft SDK\Lib\IA64 (AMD64) in the top of lib directories. (Tools->Options->VC++ Directories).

Thankx Sarath
after Changing the settings as u said i got the following error
LINK : warning LNK4076: invalid incremental status file '.\Debug/eSLogOn.ilk'; linking nonincrementally

Try the other folder amd64. In my understanding x86 actually renamed to AMD64.

I am currently trying to get the bitarray of bitmap that has already been loaded into a picture box of a dialog window when I press a button on the dialog.
The overall aim is, Button 1 takes data from user, takes editing parameters and creates a BMP from it the result of the editing , putting the BMP into a picture box in a dialog. Button 2 is the "save" feature, which allows the final changed Bitmap to be saved back into bitmapbits array.
Here's the problem:
void CProjectDlg::OnButton2Press()
{
CFile TestFile;
HBITMAP CapturedBMP = m_PicBox.GetBitmap();
CBitmap RS232BMP;
RS232BMP.Attach(CapturedBMP);
BITMAP TempBMStore;
RS232BMP.GetBitmap(&TempBMStore);
BYTE* bmpBuffer=(BYTE*)GlobalAlloc(GPTR, TempBMStore.bmWidthBytes*TempBMStore.bmHeight);
DWORD dwValue=RS232BMP.GetBitmapBits(TempBMStore.bmWidthBytes*TempBMStore.bmHeight, bmpBuffer);
}
I get a valid handle at (1) but I my TempBMStore is blank after I execute line (2), meaning I do not have a valid Bitmap or something (return value is 0). What Am I doing wrong here?
When I cut and paste this code into the section of code that originally places the bitmap into the picture box, I have absolutely no problem. ie:
void CProjectDlg::OnButton1Press()
{
.
.
.
<get data="" from="" user="">
.
.
.
<edit the="" bitmap="" bit="" values="">
.
.
.
m_PicBox.SetBitmap(TmpBmp);
CFile TestFile;
HBITMAP CapturedBMP = m_PicBox.GetBitmap();
CBitmap RS232BMP;
RS232BMP.Attach(CapturedBMP);
BITMAP TempBMStore;
RS232BMP.GetBitmap(&TempBMStore);
BYTE* bmpBuffer=(BYTE*)GlobalAlloc(GPTR, TempBMStore.bmWidthBytes*TempBMStore.bmHeight);
DWORD dwValue=RS232BMP.GetBitmapBits(TempBMStore.bmWidthBytes*TempBMStore.bmHeight, bmpBuffer);
}<pre>
Thje return for line (2) is valid and I can get the bitmap bits with no errors. Same code, different behaviour. Do I need to make the Picture Box valid or something?
Thanks in advance
|
|
|
|
|
Is it possible that TmpBmp in your OnButton1Press is a local variable and when the method returns it destroys the bitmap so when you later try to access it you get an invalid handle? (CBitmap's destructor destroys the bitmap associated with it)
> The problem with computers is that they do what you tell them to do and not what you want them to do. <

|

Never thought of it that way. Thought the Picture box would store the data so I can retrieve it later or allow another function to operate on it.
If the data object is destroyed like that, all my functions would have to be tightly coupled together. and that would be rather wierd from an OO programming POV.
You have anyway to retrieve a bitmap from a picture box object in a dialog AFTER the function that places it there destroys the CDC that was containing it?

Well, make your CBitmap a member variable of your dialog class, then the bitmap will be existent while your dialog is up, or you could use the Detach method to "disconnect" the CBitmap and the HBITMAP but i don't know if the image control is possible to destroy the bitmap for you, pay attention or you could leak GDI resources.

Dear all,
How can I tell c++ to allocate memory from Physical RAM, not virtual memory (on WinXP).
Thanks in advance,

Thanks a lot 4 ur excellent answer  .

what is the meaning of '?'and ':' in this expression?
bool Addr
int m= Addr ? 1 : 5
thanks
|
|
|
|
|
means:
int m;
if (Addr)
{
m = 1;
}
else
{
m = 5;
}
check Addr (? -> check)
if its true use first expression (1)
else use second one (5)
|
|
|
|
|
X1 ? answer1 : answer2
If X1 is true the expression will return answer1, if it is not it will return answer2 and I think you are new so see C++ Reference[^].

|
|
|
|
|
This line of code first evaluates the condition 'Addr == true'.
Then, if the condition is true assigns 1 to m, otherwise asssigns 5 to it.
