If I have strings(variables) in my application, does these strings present in the string table of exe?

A string constant in your inline code (e.g. printf("A string");) is compiled into the data portion of the object file. Such a string can be found in the exe by reading the entire file and looking for 'printable' characters. However only strings that are declared in resource string tables can be found using the FindResource() function.

I have to display all the strings present in an EXE file (i.e. compiled CPP file present in debug folder). How do i do this? I have written the following code. Can u please tell me what the problem is?.

#include "stdafx.h"
#include "windows.h"
#include "tchar.h"
#include "stdio.h"
#include "string.h"

BOOL CALLBACK MyStringCB(HMODULE some_library,LPCTSTR RT_String,LPTSTR buffer,LONG_PTR aux_param);

char buffer[200];

int _tmain(int argc, _TCHAR* argv[])
{DWORD S;
 LPCTSTR RT_String=NULL;
LONG_PTR aux_param=NULL;
	BOOL q,r;
	HMODULE some_library = LoadLibrary("C:/Hi/Debug/Hi.exe");
	q=  MyStringCB(some_library,RT_String,buffer,aux_param);
r=EnumResourceNames(some_library, RT_STRING, MyStringCB, aux_param);

S=GetLastError();

return 0;

}

BOOL CALLBACK MyStringCB(HMODULE some_library,LPCTSTR RT_String,LPTSTR buffer,LONG_PTR aux_param)
 {  DWORD startId = ((DWORD)buffer - 1) * 16; 
 DWORD i, endId = startId + 16;
   for (i = startId ; i < endId; ++i) 
 {    LoadString(some_library, i,buffer,sizeof(buffer)); 
 } 
 return TRUE;
 }

You are loading the string but you do not diplay it anywhere...

Sorry, but this really does not explain your problem. From some of your other questions and answers I suggest you may need to study this item on Resources.

Literals are NOT stored in the string table, if I guessed what are you asking... Roll eyes | :rolleyes:

Put your strings into a stringtable.

That's what how to put it into string table and then how to display it from EXE?

Create a resource file (.rc) and add your string(s) to the stringtable. Then you can simply load the strings with LoadString() or CString::LoadString() if you are using MFC.

TrackPopupMenuEx not popup menu on rite cordinates in ListCtrl.

Are you the same person as the thread starter? Or do you just have the exact same problem?

Anyway, it very much depends on how you created your application. If you used a Visual Studio wizard then you will possibly already have a resource script included in your project, depending on which app type you chose.

If not - and you are using Visual Studio - it's very simple to add resources to your project. Look at the documentation.

Hi all,

i want to use Menu on right click of ListCtrl,

i m using this code

void CTest::OnNMRClickList(NMHDR *pNMHDR, LRESULT *pResult)
{
	LPNMITEMACTIVATE pia = (LPNMITEMACTIVATE)pNMHDR;

	UINT flags; 
    DWORD pos = GetMessagePos(); 
	
	CPoint point(LOWORD(pos), HIWORD(pos));

    m_List.ScreenToClient(&point); 
    int nItem = m_List.HitTest(point, &flags);

	
	HMENU hMenu = ::CreatePopupMenu();
	if (NULL != hMenu)
	{
		// add a few test items
		::AppendMenu(hMenu, MF_STRING,   1, "Test1");
		::AppendMenu(hMenu, MF_SEPARATOR,2,	"");
		::AppendMenu(hMenu, MF_STRING,   3, "Test2");
		::AppendMenu(hMenu, MF_SEPARATOR,4,	"");
		::AppendMenu(hMenu, MF_STRING,   5, "Test3");
		ClientToScreen(&point);

		int sel = ::TrackPopupMenuEx(hMenu,TPM_LEFTALIGN|TPM_RETURNCMD,point.x,point.y,m_hWnd,NULL);

		switch(sel)
		{

I think perhaps this is where your problem lies. The list box returns the cursor position in the LPNMITEMACTIVATE structure. You will need to convert this position to its absolute screenvalues via
ClientToScreen(hWnd, &pia->ptAction);
and then use pia->ptAction.x and pia->ptAction.y in your call to TrackPopupMenuEx().

Now i m using like this

CPoint point(LOWORD(pos), HIWORD(pos));

int nItem = m_List.HitTest(point, &flags);
HMENU hMenu = ::CreatePopupMenu();
if (NULL != hMenu)
{
    // add a few test items
    ::AppendMenu(hMenu, MF_STRING,   1, "Test1");
    ::AppendMenu(hMenu, MF_SEPARATOR,2, "");
    ::AppendMenu(hMenu, MF_STRING,   3, "Test2");
    ::AppendMenu(hMenu, MF_SEPARATOR,4, "");
    ::AppendMenu(hMenu, MF_STRING,   5, "Test3");

    ClientToScreen(&pia->ptAction);

    int sel = ::TrackPopupMenuEx(hMenu,TPM_LEFTALIGN|TPM_RETURNCMD,pia->ptAction.x,pia->ptAction.y,m_hWnd,NULL);

    switch(sel)
    {
    case 1:
        {
            //do sumthing

This looks correct now, so I am at a loss to understand why it does not poup at the correct location. Where does it appear on your system relative to the screen? You may also like to use the debugger to check the values of x and y before and after the ClientToScreen(&pia->ptAction); call.
