Hi Guys,
I have added one edit control to a dialog and attached a string variable to that. But i want only integers can be entered to the edit control and not characters.(N.B. I have attached a string variable to that edit control because i want that value to be received as string. Please help.

Subclass CEdit and handle WM_CHAR message.
If the char entered is a valid number then call base class implementation else you can ignore the char.

Instead of creating the control variable of edit box as string, use integer type. if u wan to get the number as string just use the "Format" function of the CString.
Then set Number (ES_NUMBER) style of the edit box, which only allows interger to enter.

There is another way toooooooo
Add the Number style to Edit. Whenever you want text in the edit box, Just call
GetWindowText()

Thanks a lot to all of you as all are good suggestions. But as per my requrement i feel "Add the Number style to Edit" will be the best solution. But i do not know exactly how to set it and also i am not able find the same.
Nave,
Can you please tell me how to set this style.

|
|
|
|
right click on the edit box -> take style tab
There u can find the a check box named Number

on the resource editor, there is a "decimal" property which make the editBox accept only the 10 decimal digits...
if you'd like to allow the . character, or a sign character like + or -, you'll have to overload the WM_CHAR event...

Hello i have a menu resource that i want to attach to a Window and i don't know how to do it
Thank you very much for your help
A C++ illiterate...

First Load menu resource using LoadMenu(...)
Second Set menu for the frame using SetMenu(...)
For eg:
CFrameWnd *pFrameWnd = (CFrameWnd *)AfxGetMainWnd();
CMenu cmenu;
cmenu.LoadMenu(IDR_MYMENU_RESOURCE)
pFrameWnd->SetMenu(&cmenu);
pFrameWnd->DrawMenuBar();

Transfer the above code to OnInitDialog.

on the resource design editor, open your dialog/frame and check its properties ; you'll find a "menu" option... there, change it for you IDR_MYMENU
please, don't leave it as IDR_MENU1 as the wizard autogenerate ; give it a more significant name

hi, I am student and am actually doing a project on landscape generator... its quite tough.. my problem is that am nt being able to load a bitmap image from files to my picture box when the user click on a specific button.. plz help me...
|
|
|
|
|
Try the code below
HBITMAP hBitmap = (HBITMAP)LoadImage( 0, csFileName,IMAGE_BITMAP,
100,80,LR_LOADFROMFILE );
// m_static is the control variable for the picture box
m_static.SetBitmap( hBitmap );
nave
|
|
|
|
|
#include <atlimage.h>
...
...
CImage m_image;
m_image.Load(m_FileName);//For Load Graphic Files
then
if draw Picture inthe Screen you use Event WM_PAINT and function BitBlt
For Static Control //CStatic
SetBitmap
else
for Buttons
you need OWNERDRAW in the property butoon
then
SetBitmap
You use CbitmapButton
else
For ListCtrl
you should use CImageList
else
in the Site CodeProject Directory Bitmap is good
,......
Have a nice day

Here's one way (I assume you want to load from a file):
1. Add a picture control to the dialog, be sure to set its type to "bitmap". Change to ID to something meaningful.
2. Using the ClassWizard add a member variable of type CStatic for the control, call it m_Picture.
3. Add the following to your class declaration:
HBITMAP m_hBM;
4. Add the following code to the dialog's OnInitDialog handler:
HBITMAP m_hBM = reinterpret_cast<HBITMAP>(
LoadImage(
NULL,
_T("C:\\130x130.bmp"),
IMAGE_BITMAP,
0,
0,
LR_LOADFROMFILE
)
);
m_Picture.SetBitmap(m_hBM);
5. Add the following in a WM_DESTROY handler:
DeleteObject(m_hBM);

Hi Guys,
In "File View" of my visual studio's work space when i "Right Click->Add Files to Folder" its giving me one error like "Microsoft Developer(R) Studio has encounted a problem and you need to close it..............." When i am closing it then its not even closing rather the hour glass comes and it's taking too much time. For your information i am working on a visual c++ project.I will appreciate if any one can tell what is the cause and how to fix it.

This seems to be a application bug. Try this: open the file in your Visual Studio and rightclick in the file window. There is also a menuitem 'Add to project' (or similar). If this doesn't work you have possible to reinstall your DevStudio.
