Why?

VB6 doesn't allow multithreading.
VB.NET allows it.

"How do I call a function from within VB code?" is a VB question. In any case, you'll need something like:

I guess you would create additional threads via CreateThread().

Hi all:
In C: when a program terminates correctly, we write
return EXIT_SUCCESS; otherwise
return EXIT_FAILURE;
How about C++, I know in C++ EXIT_SUCCESS and EXIT_FAILURE are not defined. Is there any programming convention I should follow apart from writing plain:
return 0; or
return 1;
Thank you

Never seen that before...
I would just return 1 or 0, but you can #define them any way you like.

What a program returns (to the calling process) is independent of the language used.

You can use of CB_ADDSTRING or CB_INSERTSTRING and for MFC m_Combo.AddString("Hello"); or InsertString(-1 for insert string to end of list,"Hello");

Hi all:
I am writing a program which accepts two command in parameters, "the program name" and "the file it accesses".
My codes are:
#include <iostream>
#include <fstream>
using namespace std;
int main (int argc, char* argv[])
{
ifstream in(argv[1], ios_base::binary);
if (argc != 2) {
cerr <<"Usage: conc file" <
|
|
|
|
|
C_Zealot wrote: It compiles with no errors, but it will crash if argc = 1, e.g. there is no file name given.
Why?
because in that case argv[1] will try to access invalid memory and may cause access violation.
You should put the if (argc != 2) checking above the ifstream in(argv[1], ios_base::binary);

:->I have created a class CSkinDesignerDlg derived from CDialog.As its default background color is too normal,I want to change its color.After having searched on the web,I find a way to change its color.Draw its back color in function "OnPaint()",just like below:
void CSkinDesignerDlg::OnPaint()
{
................
CPaintDC dc(this);
CRect rect;
GetClientRect(rect);
dc.FillSolidRect(rect, RGB(0,0,255));
.................
}
As I will always need to show or hide this Dialog form in my program,there will be a shimmer in my program.Is there anybody know some better way to change the background color.
|

|

I made it in this way :
in OnCtlColor( CDC pDC ...)
you replace the core with :
if((nCtlColor == CTLCOLOR_STATIC) || (nCtlColor == CTLCOLOR_DLG) ) {
pDC->SetBkColor(RGB(255,255,255));
return (HBRUSH) MyBrush;
}
( HBRUSH hbr = ... rests )
where MyBrush is of Type CBrush and will be initialized via MyBrush.CreateSolidBrush(RGB(255,255,255));
I hope it helps

I know "OnCtlColor()" is used to set child control's color.And I have also tried to use it. But it seem doesn't work, still have glimmer.
Now I will have a more detail introduction of my software. It has a main form.In the main form,there are a lot of child forms. There's a tab control in the main form which I could used to choose which child form to display. As I have changed the main form and child form's background color(main form and child form have different color), there will always be a glimmer when I change the child form to display.
Is there anybody can help me solve this problem.
Thanks to all the helper.

 Sorry, I said wrong. It works, but still glimmer.
I have tried "CWnd::OnEraseBkgnd(...)". And only paint the area that I need to redraw. Now it shows well, do not have any glimmer.

Well it seems that your problem solved.;)

You can use of these messages (of the MSDN)
CTLCOLOR_BTN Button control
CTLCOLOR_DLG Dialog box
CTLCOLOR_EDIT Edit control
CTLCOLOR_LISTBOX List-box control
CTLCOLOR_MSGBOX Message box
CTLCOLOR_SCROLLBAR Scroll-bar control
CTLCOLOR_STATIC Static control

You have tried using the CWnd::OnEraseBkgnd(...) function to paint the background yourself? Doing it in the CWnd::OnPaint(...) function may not be the best place because I think that it will only update any region that is marked as invalidated, so parts of the dialog may not get painted correctly.
Peace!
