I want add or del the resources in EXE files. I know I can do it in VC if I have sourcecode. But is there any tool to do this ? Or I can write a easy tool to do this ? Please give me some hints and Thx.

You can do this in VS6 IDE this way:
1) Call OpenFile dialog from menu File/Open...
2) In Files of type combo select Executable files
3) In Open as combo select Resources
4) After you open the executable file with these settings, you can edit the resources as usual.
5) Save the modified resources back into exe using save.

static member in dll

I have a dll using MFC7 (.NET)
To export the functions from my class to the dll, I use the keywords __declspec(dllexport) (see code below).
In my class I have a static member.
My problem is that I can't have access to my static member from an external application using the dll. There is the below error:
Application error LNK2020: token not solved (0A000022) ?version@CIO@@2PBDB
How to have access to the static member from an external application????

<br />
class __declspec(dllexport) CIO<br />
{<br />
public:    <br />
     CIO();<br />
     ~CIO();<br />
<br />
public:<br />
    static const char* version;<br />
<br />
};<br />

Usually how people solve this problem is by making a define that gets changed depending on how the DLL is used. Something like this:

<br />
#ifdef CIO_EXPORTS<br />
#define CIO_API __declspec(dllexport)<br />
#else<br />
#define CIO_API __declspec(dllimport)<br />
#endif<br />

So in your project where you compile your DLL, besure to define CIO_EXPORTS, and your class and static members will be exported. In all other cases (like the project where you want to import the DLL) the setting will be set to import those parameters.

I think it is when you have an modal dialog box open (is it a modal dialog box?).
Then when you as you do to give it focus you can't give it focus because you have an modal dialog box open....

I only think it could be that... I'm not sure! Smile | :)

hi,
Roles:
a DLL, a Callback function and an Exe.

Activity:
sending a CListCtrl's Handle through Callback Parameter list to DLL for displaying coming data from COM1.

Precodition:
the CListCtrl has three columns, no problem in Dialog

Subsequence:
can only insert data into Item, not SubItems, in the columns of CListCtrl in Callback function.

Question:
what's happening?
How to insert data into SubItems as well?

Addition:
Thanks in advance

Extreme programming. Do the No.1

That's the way to insert subitems:

LVITEM pItem;
pItem.iItem = iIndex;
pItem.mask = TVIF_TEXT;
pItem.iSubItem = iSubItem; 
pItem.pszText = (LPTSTR)(LPCTSTR)"SubItem text"; // <- I know this cast is bad, how to make it better?
m_ctlListCtrl.SetItem(&pItem);

Export functions in an exe

How do you export functions in an exe? There is no def file to use. What I want to be able to do is use an exe the same way as I do an dll. I want to be able to do the same thing as the excel.exe file. Any ideas?

You just export all funktions the same way you do in a DLL!

From what I know about dlls is: If my functions aren't in the def file, I cannot get a pointer to the functoins. Do you not need it in an exe? Also, will I need to export the entire class? If anyone has done this and would care to share please do.

You could be right!
I haven't tried exporting functions from an exe yet! Unsure | :~

You can't export member functions of an class.
You'll need to make them static if so... I hope...

try something like
class __declspec(dllexport) ABCD
{
public:
void junk(){}
}

and if you have a simple function:
int _declspec(dllexport) myfunction();

and variables:
int _declspec(dllexport) myvariable;
