Hi, guys,
is there a way to intercept mouse clicks or keystrokes when an application runs in the background (a window does not have a focus) without using global Win32 hooks?
Thanks a lot.

I have 16 project that I only have the source code for that I would like to put into a Solution. I have been able to create a solution with all the 16 project directories, but when I view this in the Solution Config it only show the Project for which the Solution was create. Thus I can't compile and run each of the 16 project by them selves.
Kind of looks like this:
Solution A
StartServer
.C/.Cpp/.h
ShutdownServer
.C/.Cpp/.h
.
.
.
RunReport
.C/.Cpp/.h
Directory file structure is:
c:\Solution A\
c:\Solution A\StartServer\
c:\Solution A\ShutdownServer\
...
c:\Solution A\RunReport
Config file only shows Solution A thus it compile all 16 everytime...
I should be able to select on of the projects and compile/run it.
Any help would be much appriciated.

To do this you either have to right click on the project in the Solution Explorer window and select Project Only/Build Only... from the menu
Or you can select the project you want to build as the startup project, and under the build menu select the second set of build commands, the ones that have the project name in the menu item.
Selecting Build Solution (Ctrl+B) will build the entire solution which is all the project.
Also check the dependency of the projects to make sure they are correct. (Menu Project/Project Dependencies.

I'm trying to load a disk file into memory and the program crashes when it tries to exit. As far as I can tell the file never got loaded. The compiler dosen't catch the error, but the debugger did point to this part of ios.cpp when it crashed, the line has a smilie next to it:
<br />
ios_base::~ios_base()<br />
{
if (0 < _Stdstr && 0 < --stdopens[_Stdstr]):mad:<br />
return;<br />
_Tidy();<br />
_DELETE_CRT(_Ploc);<br />
}
My specification file code:
#include "DnD_Common_Defs.h"<br />
#include "windows.h"<br />
#include <iostream><br />
#include <string><br />
#include <fstream><br />
<br />
using namespace std;<br />
<br />
class DataLoading<br />
{<br />
public:<br />
DataLoading();
RaceDataType ReturnRaceData(int RaceToReturn);<br />
protected:<br />
bool LoadUpRaceData(string FileName);
private:<br />
int NumBaseRaces;<br />
ifstream inData;

which line in your function triggered your error? In the future, please post with pre instead of code; it preserves formatting.

Hi ,
I have to develop an application in .Net ,C# .
1.If a user tries to open a file in his System the request is sent to the System Admin (Server) and only if he(Admin) permits the user will be able to open the file.
Any Ideas............
Thanks in advance.

You need to intercept all the system services used to open files.
To do that you need a system hook, is more, you'll need a Kernel mode driver to install the hook.
Forget about C# and start learning WIN32 and Assembler.
What you try to do is really f***ing hard, I can tell you because I was working in a project similar to what you say.
Anton Basov articles would be really helpfull in your task, you can find them in the code project.
Hope this helps

You'd get a lot more help if you'd narrow this down to just a handful of lines. No one likes to wade through complete programs, or even several pages of code, to locate a problem. Try:
void main( void )
{
char host[1024], szModName[1024], *host1;
if (! (host1 = strrchr(szModName, '\\')))
strcpy(host, szModName);
else
strcpy(host, host1 + 1);
FILE *fout = fopen("out.txt", "a+");
fwrite(host, 1, strlen(host), fout);
fclose(fout);
}Now step through each of these until you locate the offending statement.

are you sure you are looking at the correct out.txt file?
because this code looks fine: (isolated that is)
fout = fopen("out.txt", "a+");
fwrite(host, 1,strlen(host), fout);
fclose(fout);
Is this a Unicode project?

Hi again people
How can I get a list of the running apps, like the one is shown in Task Manager in the Applications tab?
Thanks in advance 
|
|
|
|
|
|
Thanks mate, I already know about enumprocess, but that will list all the running process, like svchost.exe, lsass and all that.
What I would really like is to see only the Apps running.
Is there any way to filter the process list to get only the Apps?

Does EnumWindows give you what you want?

I think that EnumWindows is what I was looking for
I found also that task manager considers Application to any process with a visible window.
Thanks a lot Ali
