You mean that before your application is up and running you want to show a splash screen sort of logo

I think you could use your "About dialogbox" for the same. DoModal your aboutbox then use a timer to make it disappear after a while. (EndDialog)

If you need to show the dialog you can display it by getting the bitmap handle and loading it.
Secondly you can take the picture controla nd set the log to it from the resource.

Private Declare Function concat Lib "d:\StringConcat1.dll" (ByVal Text1 As String, ByVal Text2 As String) As String
Private Sub Command1_Click()
Text3.Text = concat(Text1.Text, Text2.Text)
a = Len(concat(Text1.Text, Text2.Text))
MsgBox a
End Sub
The function of the vb code is given below. The form has three text fields
a) The first text field , enter the first string
b) The second text field , enter the second string
c) The third text field, concatation of the two string i.e result of the two strings is shown in third text field
d) One Command button at the bottom of the form.
When we call "StringConcat1.dll" dll the value entered through the two text fields is send as a argument by value to the dll and Concatenation of the strings is done in C++ .
the dll code is given below "test.cpp"
#include
char* __stdcall concat(char *string1 , char *string2)
{
return strcat(string1,string2);
}
the def is given "test.def"
LIBRARY StringConcat1
EXPORTS
concat @1
When I debug the code , the Concatenation is done in C++ but when the result is given to vb code ie front end only the first string that is entered in the first text is shown only as the output in the third text field.
for example
text1 : india
text2 : people
result text3 : india ( but the result should be indiapeople after the concatenation is done in C++(i.e dll does the function for concatenation , but the result shown is here is only "india").
Kindly note the point:
the C++ code works perfectly.
After computation ie Concatenation , the result is not shown in the vb code only text1 input is shown in text3 field.
Can any help me in this matter

It's much more complicated than you think ! VB and C++ don't have the same format for string representation. It works the way you did to pass string from VB to C++ but the other way is more complicated (the return of the string).
But my question is: why do you want to call a dll to concatenate two strings  ? What is the exact purpose of this dll ? why don't you simply concatenate the two strings in VB ?

Before returning, try this.
<br />
char* __stdcall concat(char *string1 , char *string2)<br />
{<br />
strcat(string1,string2);<br />
AfxMessageBox(string1)<br />
AfxMessageBox(string1);oops sorry not like this.<br />
return strcat(string1,string2);<br />
return(string1);<br />
}<br />
And tell me what you get.
also
<br />
a = Len(concat(Text1.Text, Text2.Text))<br />
MsgBox a<br />
What's the length of the resultant text? I think it could only be of the first string's length. (as you get only the 1st string as the result).
Ok tell me what you got in the AfxMessageBox, If it's not an MFC DLL, try using MessageBox..
And Also remove the BOLD SHOUT please...

I suggest you would go for an ATL (COM)DLL if you want to integrate you C++ code into VB. Which would be hassle free

The strcat(string1, string2) looks suspicious: since the strcat function stores the result of concatenation in the first string, the string1 passed from Visual Basic may not have enough room for concatenated destination string.

if you want to change shape use
HCURSOR hcur=LoadCursor(AfxGetApp()->m_hInstance,(LPCTSTR)IDC_HAND);
SetCursor(hcur);

I think you should instantiate the CWaitCursor class like this:
CWaitCursor pLengthyOperation; Good luck and keep the good coding! CWaitCursor Class[^]
|
|
|
|
|
See my post below.
And Yes SetCursor is used to set the shape of the cursor.

As said above, you could use SetCusrsor, see to that you use :: global scope to use it. ::SetCursor(hcursor)

again same error IDC_HAND undeclared identifier
|
|
|
|
|
<br />
#ifndef IDC_HAND<br />
#define IDC_HAND MAKEINTRESOURCE(32649) <br />
#endif<br />
Put these lines of the code somewhere at the top of the file where you are using IDC_HAND.
It will work

thank u very much.
but it's not working as we intended.hand symbol is not getting
|
|
|
|
|
Put Sleep(10000); after the statement SetCursor() and you will be able to see the cursor in the shape of the hand

Hey, try this : Go to insert menu, select resource, select Cursor type, click on import, now you select any .cur file you want to display. So many types are available in C:\windows\cursors directory. Now your cursor is included in your resource. Now, when you look into your resource.h file, you'll find a new entry,
#define IDC_CURSOR1 135, (you could change the name to IDC_CURSOR1 to IDC_HAND or anything accordingly.
now try this code :
<br />
SetClassLong(m_hWnd,GCL_HCURSOR,(LONG)LoadCursor(AfxGetInstanceHandle(), MAKEINTRESOURCE(IDC_CURSOR1)));<br />
