Yes, but how do you do that with code?

If you specify the CBS_SORT style the strings are automatically sorted when they are added with AddString().
You said you are not creating the control dynamically, so I assumed you were using a template to create it. If you are creating the control dynamically, then you use the Create() member function, and add CBS_SORT as one of the styles in the dwStyle parameter.

Yes, but I need to be able to change the setting during the program. Can I add this ability in the program? I AM using the dialog control maker (not dynamic). Thanks VERY much,

Ok, now I get what you want
You can use the ModifyStyle() function. Just remember that some styles can not be changed after the control is created, I am not sure if CBS_SORT is one of them or not. Also, after you modify some styles you may have to call RedrawWindow() or SetWindowPos() with the SWP_FRAMECHANGED flag in order for the changes to show.

When the user changes the selection of a combo box, I receive the CBN_SELCHANGE notification (via the MFC callback mechanism). The problem is that the UpdateData(TRUE) with the handler sets the CString to the previous.
Who was this guy at Microsoft who might think that if a user changes the Combo box selection that I would be interested in the previous selection, not in the new?
Btw, I tried catching the CBN_EDITCHANGE, CBN_EDITUPDATE, CBN_CLOSEUP, and CBN_SELENDOK notifications. They all return the previous selection, except for CBN_EDITCHANGE and CBN_EDITUPDATE that are never called.

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

AFAIK, the window is not actually updated until the message handler returns.
Use GetCurSel() and GetLBText() to get the new selection.

|
|
|

Using UpdateData(TRUE) would have been too simple, isn't it? Btw, when do I call these functions?
What I want to do is to update another control when the user changes the selection.

You should be able to call them from your CBN_CHANGE (from memory & it's early - something like that) handler. Heck, you could even put them in your DoDataExchange() method if you just want to keep using UpdateData() (make sure you only do it when going one way).

You need to call UpdateData(FALSE) in your handler to get the current value updated from the combo. Then you can do your other processing and call UpdateData(TRUE)
The opinions expressed in this communication do not necessarily represent those of the author (especially if you find them impolite, discourteous or inflammatory).

Phil, I think it is the reverse. Anyway, UpdateData(TRUE) don't get the value from the combo box.

in hw3.h you need a semicolon after the closing brace in your class declaration.
#ifndef hw3_h
#define hw3_h
class Date
{
private:
int month;
int day;
int year;
public:
void setdate(int, int, int);

the 3 lasts errors come from this:
int days_array{} = {31, 28, 31, 30, 31, 30,31, 31, 30, 31, 30, 31};
I suppose, you wanted to write that:
int days_array[12] = {31, 28, 31, 30, 31, 30,31, 31, 30, 31, 30, 31};
.... I think ....

i hope that someone can answer this question cause i spent about two hours on it last night and came no closer.. I have this sample code on socket programming, but it says that i have to link in the ws2_32.lib for support of some classes. Unfortunately i don't know how to enable this option in visual studio.net!!!! can anyone answer this. Can i compile socket programs using the visual IDE or does it have to be done with the command prompt. If so, could you help me find a tutorial that might help on using the command prompt compiler? Thanks, any help would be appreciated. I have joined this group because a lot of you seem well experienced with visual c++. i am dying to make some socket programs..

i have tried this:
in the solution explorer > right clicked on the project name > properties > expanded linker (folder) > input >
then in the additional dependencies i tried two things..
first i put the path C:\Program Files\Microsoft Visual Studio .NET\Vc7\PlatformSDK\lib .....<didn't work="">.....
then i just put C:\Program Files\Microsoft Visual Studio .NET\Vc7\PlatformSDK\lib\ws2_32.lib ....<didn't work="">....
then i just put ws2_32.lib and again. ....<didn't work="">.....

If I have to link to an extra library, I usually use a #pragma in the .cpp file that requires it.
#pragma comment(lib, "ws2_32.lib") Or, you could use the project settings dialog
- Project menu -> Settings (or Alt-F7)
- Link tab
- Object/Library modules edit box
- Add ws2_32.lib to the end of the list

are you using visual Studio.net cause i am and i don't see a settings and when i press (Alt-F7), it does nothing. also when i am in the property pages dialog all i see is a bunch of folders, one of which is called linker... so i open that and i see these options..
-additional dependencies
-ignore all default libraries
-ignore specific library
-module definition file
-add module to assembly
-embed managed resource file
-force symbol references
-delay loaded dlls
i have tried putting this line in all of the above
C:\Program Files\Microsoft Visual Studio .NET\Vc7\PlatformSDK\lib
with no luck!
am i in the right dialog... is that right way to do it??
also when i used that #pragma, it didn't help i am still receiving this error.

Did you #include "stdafx.h"?
Alt-F7 is for VC6, sorry about that. But VC7 should have something similar.

Should be the one. type "ws2_32.lib" (no quotes) in there and see what happens

Hi all,
I have two question regarding win programming.
I have a simple application.
***********************
char str[10];
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_LBUTTONDOWN:
sprintf(str, "arg1 = %d, arg2 = %d" , argv[1], argv[2]);
MessageBox(NULL, "Hello", str, __FILE__, MB_OK);
break;
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = NULL;
wc.lpszClassName = g_szClassName;
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
hwnd = CreateWindowEx(
0,
g_szClassName,
"theForger's Tutorial Application",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, 480, 320,
NULL, NULL, hInstance, NULL);
if(hwnd == NULL)
{
MessageBox(NULL, "Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
while(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
*****************************************
First question is:
How to give argv[1] argv[2] etc arguments to win app as one can give to console application.
What I want is when left button is clicked the argument given to the program should appear in a dialog box.
Better if you send me a simple code example.
My second question:
I am using Visual Studio C++ 6.0.
Say, the above app is Test.exe and I want to run this application a number of times with different arguments though Visual studio IDE and not through a batch file on dose command.
Now my question is, is there any way I can write a script in VS C++, like a bat file in dose and if so how?
Script file may look like:
Test.exe 2 3
Test.exe 4 5
Test.exe 6 7
Test.exe 8 9
Test.exe 10 11
............
...........
thanks in advance
regards

Use the GetCommandLine() function to get your program's arguments. There are also __argc and __argv, which is a VC featue that the compiler sets up. You can use those variables just like argc/argv.
