How does one make static text (in)visible in VC++? I can't find this out in all of the books I have or the MSDN. I'm looking for something similar to the VB object.visible property in VC++.
Thanks,
Marc

Marc,
I think you are looking for ShowWindow function. It is a member of CWnd, so you can be sure that all window controls have it. Use it as:
ShowWindow( SW_SHOW ); -- to make a window visible
ShowWindow( SW_HIDE ); -- to hide a window

Just do : GetDlgItem(IDC_STATIC_IDNNN)->ShowWindow(SW_HIDE); of course for this each one of the items u wish to hide should have a unique id.

Is there a "code keeper / code bank" type program written in VC++ w/source code available?
Thanks,
Marc

I don't exactly know what you're referring to but it sounds an awful lot like a DLL. In other words, when you have some common code that other apps may need to use, you put it in a DLL and presto.

This must be easy BUT.....
I've tried to change the font on a single CEdit box in a dialog. I've used the following code....
CFont m_Font;
m_Font.CreateFont(.........);
GetDlgItem(CEDIT_ID)->SetFont(&m_Font);
Now this "sort of" works. The font is changed BUT the line size of the CEdit is not changed accordingly so the lines below overlap lines above.
Can someone please sell me how this can be done??
Thanks in advance

Hi Jeremy!
I think your have problems because you are creating font in the local variable and as soon as it go out of scope the font is destroyed.
The lifetime of the CFont object should be the same as your edit control. The best thing to do this is to add a CFont variable to your dialog class.

I would like to know how I can execute another program
from within my MFC apps.

To execute another program from within your MFC/SDK application you can use 'ShellExecute'.

I recommend using the _exec function or any of the variations of it. Look it up in C++ help since the command instructions are extensive.
Best wishes for the holday!

I use a dropdown combobox. By runtime the combobox style should be changed from CBS_DROPDOWN to CBS_DROPDOWNLIST. How can I do that.
Thank you for your help

Hi !
You can't change the style of the combo box after creating because different windows are created inside the control depending on the style.
For combo boxes created with the CBS_SIMPLE styles, the ComboBox window is the parent of the edit control and the list box that is always displayed on the screen.
Combo boxes created with the CBS_DROPDOWNLIST style have no edit control. The region of the combo box that displays the current selection is in the ComboBox window itself.
For combo boxes created with the CBS_DROPDOWN style, three windows are created. The combo box edit control is a child of the ComboBox window.
What I suggest you to do is either destroy and recreate control with different style or have two controls in the same position and hide/show one of them.

I'm not 100% positive...but I believe you can... try this in your InitDialog function
GetDlgItem(IDC_YOURCOMBO)->ModifyStyle(CBS_DROPDOWN,CBS_DROPDOWNLIST,0);
You may or may not need a :: in front of the GetDlgItem...whichever will give you a CWnd.

Hi Carole!
Modifying the style of the combo box will work only if you do this before the window creation. After that it will not work.

Maybe he could put it in the PreCreateWindow then.....
Haven't tried it...but would be worth a shot.

I have multiply views and document in seperate MFC DLLs and every view has its own toolbar. When i open new document in the same view it create again the toolbars (The code of create toolbars its on the constructor of the view). How i can modify the code to not recreate the toolsbar and i have the creation and the control of the toolbars in the same DLL because different DLL loaded in different version of the program.

a window is resizable, but when the length of window excede 300 pixels (for example), it can NOT make larger and stop resizing. How ? Thanks in advanced

You could catch the WM_SIZE message and check to see if the width is greater than you want it to be and then reset it to 300.

Read up on WM_GETMINMAXINFO. Windows sends this to you as the user is resizing the window. You fill in a MINMAXINFO struct with the min/max sizes, and Windows will not let the window be sized outside of those bounds.

I've got a set of filenames: some are to files which exist, others are to files which do not exist;
some are absolute, others are relative; some are on local drives, others on network drives.
I'm looking for a way to extract the drive name from a file path, regardless of any of the above
factors.
Can anyone give me a pointer of where to look for this?
Thanx.
