Re: Help with modeless dialog error

The dialog IDs are defined in resource.h
So add #include "resource.h" in your corresponding cpp file which shows the error.

You can also edit TestDialog.h and put

#include "resource.h"

at the top, before your CTestDialog declaration.

I just tried this in VS 2008 and it compiles without any problem. What version of visual studio you are using and what type of MFC application you are working with?

i use vs 6.0
and what drives me crazy is that i have another application that works FINE
but when i created anew one with the same steps
it gave me 70 errors starting with:
error C2501: '_ConnectionPtr' : missing storage-class or type specifiers
what should i do ????
i traced the two applications line by line but nothing is different....

I can understand your frustration but I do believe that something has to be different. If everything is same in two projects then it is not possible for one project to work and other to fail. So I will recomment that you try comparing the differences between two projects using winmerge[^]. It can compare differences between two directories as well.

Detours TerminateProcess API Function

I'm trying to use Detours Library to prevent a Termination of a specific process
through the Task Manager, so I hooked a DLL in the Task Manager.
The Hooking part is fine, but the checking of which process is been terminated
not working for me.

i dont know what is wrong with this code

the if statement always returning false...

by the way the detours part is working ok.

BOOL My_TerminateProcess(HANDLE hProcess, UINT uExitCode)
{

TCHAR szName[MAX_PATH];

if (GetModuleFileNameExA(hProcess, GetModuleHandle(NULL), szName, MAX_PATH) != 0)

{

std::string str1(szName,MAX_PATH);

std::string str2="notepad.exe";


std::string::size_type pos = 0;

pos = str1.find(str2);

if (pos>0 && pos < 70)

{

return false;

}

else

{

return Real_TerminateProcess(hProcess, uExitCode);

}

}

return false;

}

Check the error code by adding @err,hr in watch window. You'll get the reason - why that function call is failed.

BTW one more point,

darx wrote:
TCHAR szName[MAX_PATH];

if (GetModuleFileNameExA(hProcess, GetModuleHandle(NULL), szName, MAX_PATH) != 0)

You've used szName as TCHAR and called the ansi version - GetModuleFileNameExA(). Just call GetModuleFileNameEx(). If you compile this in unicode, this will pop error. Just an observation.

Jijo.

Which if is failing GetModuleFileNameExA or the inner one. If outer one is failing then you can try GetProcessImageFileName. In you code why are you using GetModuleHandle(NULL), when used in this way it will return a handle to the file used to create the calling process (.exe file). I think you should just pass NULL in the module handle.

I tried using "GetProcessImagefileName()"
but I get "Access denied" GetLastError()

I also tried to use "GetProcessId(hProcess);
and I got the same Error

so I figured that I have to "SetSecurityInfo" to the
process, but I'm not Exactly sure how to Do that.

so anybody would like to help with "SetSecurityInfo"
with an example

Use '\\' instead of '\' because \ is a newline constant.

That's an assignement, not a comparison. What you are doing there is storing the character '\' in c and then checking if c is different than 0 (which is always the case because it contains the character you just assigned). You have to use == for a comparison.

yse sure i do this == in (if stattment)

Just adding one more point. This error occurs often and the best practice to avoid is to follow the following defensive style,

// The normal style.
if( variable == constant )
{
}

// The defensive style.
if( constant == variable )
{
}

For instance,

// This if statement won't cause error. Because it become an assignment statement.
if( variable = 1)
{
}

// But this one does. If you forgot the extra = here, then it will become
// assigning variable to constant and compiler will show error.
if( 1 = variable )
{
}

At first its a bit irritation for our eyes, but still it can save a lot of time. Smile | :)

Jijo.

Most modern compilers will issue a diagnostic for the

if (variable = constant)

case when set to the maximum warning level.

I find the if (constant = variable) style intensely irritating.

gg[0][i]==' " '

gg[0][i] is a character.

' " ' is three characters.

just for explain
in programing i do as '"'

If its still making problem, then try this.

// Since the ascii code of double quotes is 34.
const char DoubleQuotes = 34;
...
if (gg[0][i]== DoubleQuotes )
{
}

BTW, is unicode defined in your project?

Jijo.
