I have a problem with using function poiter. My program has two parts:
part 1: mydll.dll
typedef BOOL (*SpeakFunc)(const CString s);
#define DLL_EXPORT __declspec(dllexport)
BOOL DLL_EXPORT Init(HWND hwnd,SpeakFunc func)
{
...
}
part 2: adding the mydll.lib of the part 1 into the project of the part 2
in the test.cpp file of the "Test" class
typedef BOOL (*SpeakFunc)(const CString str);
extern BOOL Init(HWND hwnd,SpeakFunc func);
BOOL CTest::Speak(const CString)
{
...
}
void CTest::TestMethod()
{
...
Init (NULL,&CTest::Speak) ; // the compiler notices an error here
...
}
The error message like below:
"error C2440: 'initializing' : cannot convert from 'int (__thiscall CTest::*)(const class CString)' to 'int (__cdecl *)(const class CString)'
There is no context in which this conversion is possible"
please help me...Thanks a lot.

In "part 1" you declare SpeakFunc as a global function but in "part 2" you attempt to pass a pointer to a member function.

Hai
How Can Run a Batch file ? as We can do with ShellExecute()/CreateProcess()/System()is there any method
so i can run a batch file .

system() is ok if you don't want to keep track it till the end of the tasks in the batch file.
Otherwise you had better choose other approaches.

You can run a batch file exactly like any other executable...

ShellExecute() is probably the best way, since it will automatically look up the .bat association and run cmd.exe or whatever your command processor is.

I am trying to get my program to accept the data from an internet source, like a webpage or a java applet. Can somebody refer me to a tutorial? I don't even know where to begin!
Thanx...

can anyone tell me how do i get the current directory in VC++ code?
|
|
|
|

Hi.
You could do something like this:
char myCurDir[512];<br />
<br />
BOOL bret = GetCurrentDirectory(512, myCurDir);
After that line the variable myCurDir hold th complete path.
Regards.

Hi.
I'm writing a SDI application with 2 views. A left view, (CTreeCtrl) and an CEditView at right.
The CTreeView shows some files, (plain text files).
And when some file is clicked I want to show the content of the file in the CEditView.
I have the OnSelchanged message handle in the left view where I have read from disk the file and filled a CMyDocument::CStringArray with the texts lines.
Now start my problem: How could I show the data hold in the StringArray in the CEditView.
I know it's a simple question, but I'm something entangled with all this stuff, (I mean, multiple views stuff).
Now I'm stopped at the end of the CLeftView::OnSelchanged message handle with the data ready to be showed in the other view, but I don't know how. 
Please, I need some guide
Thankx.
Demian.

Call UpdateAllViews() on your document, and in the OnUpdate() handler in the edit view, implement code that reads the data from the document and inserts it into the edit box.

Ok Ryan.
Thank you for your answer.
But how do you insert the text in the edit view?, using SetWindowText() member function?, because I'm doing the following in OnUpdate() and it doesn't work:
CString tmp;<br />
<br />
for(i=0; i < GetDocument()->m_dumpData.GetSize(); i++)<br />
{<br />
tmp += GetDocument()->m_dumpData[i]; <br />
<br />
}<br />
<br />
GetEditCtrl().SetWindowText(tmp);
m_dumpData is the StringArray object that holds the lines of text, and I have traced that object inside the loop and I could see the data.
tmp is a CString object and my idea was add every line of text in the CStringArray to tmp and then show it with SetWindowText(). Nothing happen, no exception and no text.
Should I use a CView instead of CEditView and try to print the text lines using TextOut??
I did that before and it works, but I had some problems scrolling the view, then I though to change the view to CEditView because I think is more "natural" talking about text files.
The largest files is about 32kb, so, an Edit control should works fine.
Thank you.
Demian.

Why not? Does tmp get appended to? Is m_dumpData non-empty?

Yes m_dumpData is not empty, (I could dump the lines in the debug window) and I put a break in the line SetWindowText() and I could see what tmp contain, (all the text). But it looks like I need some refresh or something like that 'cause after calling SetWidowText() the scroll bars apears, but I can't see the text inside the edit view.
This is all my code in CMyEditView::OnUpdate() handle:
int i;<br />
<br />
if(GetDocument()->FileType== 1)<br />
{<br />
CString tmp;<br />
for(i=0; i < GetDocument()->m_dumpData.GetSize(); i++)<br />
{<br />
tmp += GetDocument()->m_dumpData[i]; <br />
TRACE("\n%s", m_dumpData[i]);
}<br />
GetEditCtrl().SetWindowText(tmp); <br />
<br />
TRACE("\nString length: %i", tmp.GetLength()); <br />
<br />
<br />
}
Thank you

Your problem is in the call to GetEditCtrl(). Once that function returns, the CEdit& is not guaranteed to exist. You need to save that to a variable if you want to use it later.

I changed to
CEdit& myEdit = GetEditCtrl();
and then
myEdit.SetWindowText(tmp); // instead of GetEditCtlr().SetWindowText(tmp)
And I get the same bug. It looks like SetWindowText() works, (I can see the scroll bars growing), but I can't see the text.

Has its color been changed to match the background?

No.
I'm trying to find the problem, but I can't.
I have commented all the lines in the OnUpdate() handle and just write:
myEdit.SetWindowText("Hello");
well, I get the same bug, it looks like "Hello" is printed in the edit view, (the caret has been moved) but I can't see the text. I have not changed the color.

I FOUND THE BUG!!!
My stupid bug!! :->
When my View was a CView, I had overwritten the OnPaint() handle!!!!
And then I move my view to CEditView but the OnPaint() handle still there!!!!.
Now I have removed the OnPaint() handle, and everything works fine.
Sorry about my stupid bug and thank you very much for your feedback.
This forum is the heaven!!!
And all of you are Gods.
