There is nothing simple about it! It only looks that way to the user. Doing drag and drop is actualy easier, since Windows has built in support for that; otherwise it would be just as hard.

closing a messagebox window

Hi have a messagebox window which has some text and an "OK" button
I have used EnumWindows to track down the handle to the messagebox window
from there i can get a cwnd* to the window.
I would like to know how to tell the messagebox to close by simulating a button click onthe OK button.
SPY++ tells me control id for the OK button is 2
so i figured a postmessage BN_CLICKED to the messagebox window with the ID set to 2 woudl work..but no luck

the messagebox needs to be closes properly not just hidden or minimized

does anyone have any suggestions/what am i missing?

regards
Bryce

Well, glad you got it. Smile | :)

As for the BN_CLICKED message, you may have needed to include the window handle as well as the ID in order for that to work.

Error C2440 on porting from VC6 to VC++.NET

Hi,

I am porting a MFC Dialog-based app from VC6 to VC++.NET. I have got the following error. I have user-defined message handler in the CMyTestApp, instead of CMyTestDlg, in the VC6 project. Does thiis error message tell me that I can not have my message handler in the CMyTestApp and the message handler has to be in the CWnd-derived class, such as CMyTestDlg?

Thansk in advance.

Dion

error C2440: 'static_cast' : cannot convert from 'LRESULT (__thiscall CMyTestApp::* )(WPARAM,LPARAM)' to 'LRESULT (__thiscall CWnd::* )(WPARAM,LPARAM)'

The logical way to find this would be to use the windows find facility and look for the definition of one of these functions, that's assuming that the MSDN docs don't tell you. I presume that they do and that's why you know the name. If you can't find it ( perhaps by using that handy windows file find function again ), then there's a good chance it's in an SDK you need to download.

Drop Down Menu Button in a CDialogBar

+Ari+1-Apr-04 12:45

Hi I need some help with dialogbars.

I have an app that has a lot of dialogbars. I want to change style of some of the buttons in a dialogbar to have an arrow and a to show a drop down menu when clicked (like the IE back and forward button, or like the MS Word buttons.)

I did some digging around and found code and examples related to CToolBar where the toolbar style is set to TBSTYLE_EX_DRAWDDARROWS and the button style is set to TBSTYLE_DROPDOWN. I could not find appropriate methods to set these styles for a CDialogBar class. Can someone help me to get my buttons to have a dropdown menu just like CToolBar?

Thanks in advance. Any help appreciated.

There is no method for setting these styles for a CDialogBar class, the styles apply to CToolBarCtrl derived classes only. To recreate the look of the buttons on a CDialogBar you will probably need to custom draw the buttons youself (or try looking at the "Button Controls" section of CP).

Your best hope would prabably be the article "Professional User Interface Suite", buried in there some where is probably code for doing what you want.

Good Luck!

3DES/ECB Mode Implementation

1-Apr-04 12:37

Hello,

I was looking for a clean 3DES implementation that uses ECB mode. Does anyone have a recommendation?

I want a PRNG. I typically use Crypto++, but Wei uses a variant of ANSI 9.17 that adds increased security against seed compromise attacks (encrypting the timestamps in CBC mode, instead of in ECB mode as is done in the standard X9.17 generator).

TIA,
Jeff

I am trying to access the Microsoft SDK help files. I've have already registerd the SDK and have created programs that use it. Now either I can not remember how to access the help files in "\help" or I never could. All these .hxt, .hxq, and etc... files mean nothing if I can not access them.

What am I missing here?

Searching the www has not helped at all (yet).

Thanks for any help you can give me.

how to add a number to a string?
can i convert from a string to double and reverse?

i want to add 4e3 Roll eyes | :rolleyes:

to this value??!!!!!!!

Lookup the "Data Conversion" functions in the MSDN library (atof).
Basicaly you convert the string to a number add the new value to the old and then use CString::Format() function to replace the string with the new value.

double old = atof(&string); // Get current value
old += new; // Add new value to old value
string.Format(_T("%f"),old); // replace sting with new value

or something simular.

I would like to distinguish the editions of windows 2000 in my network.
So far I could not find a way of doing this. It seems there is no function to get the edition of a host in win32 api. NetServerGetinfo in only returning major and minor versions of the remote computer.
How can I get the suite,edition (e.g. win 200 professional, win 200 server etc.)

a vector question

Hi,

I am declaring a std::vector<double> vX. I am filling it up using vX.push_back(aNum).

The problem is i want to put the contents of vX into DP which is defined as

double DP[];

This is because an external routine requires an array that is of the form above.

Any ideas would be appreciated.
Thanks

Kash
