Polygon tool 18-Mar-02 21:25 18-Mar-02 21:25  Help does anyone have a code for a polygon tool... urgently needed.... thanks Re: Polygon tool Christian Graus19-Mar-02 0:04 Christian Graus 19-Mar-02 0:04  Flatline wrote: urgently needed.... thanks What else is new ? A polygon tool is easy - as the user clicks, add to a vector of points, and pass in the address of item 0 into the Polygon function to draw it.

Nish Nishant19-Mar-02 0:11 Nish Nishant 19-Mar-02 0:11  It's declared in winuser.h But winuser.h is declared in windows.h I think. So open your winuser.h and search for GetWindowModuleFileName Nish My miniputt high is now 29 I do not think I can improve on that My temperament won't hold www.busterboy.org Re: Why cann't I call GetWindowModuleFileName in my raw api App?

Thomas Andersen18-Mar-02 21:00 Thomas Andersen 18-Mar-02 21:00  Hi.. I'm not the greatest codewiz, but have managed to put together a DLL which given a window name can set that window to either modal or modeless.. This is fin except that I'd rather work with window handles.. Here's where I get a problem since the program I use to call the DLL can only pass a LPCSTR , but can convert a handle to this.. I now have to convert the LPCSTR to a HWND within my dll somwhow ? If anyone have an idea I'd be very grateful /Thomas Re: HWND typecast ? alex.barylski18-Mar-02 21:16 alex.barylski 18-Mar-02 21:16  Why not change the parameters to HWND and avoid the whole typecast period...? If it's a third party DLL passing it a HWND if it expects a LPCSTR is gona cause serious problems i'd think... LPCSTR temp; HWND hwnd = (HWND)temp; "An expert is someone who has made all the mistakes in his or her field" - Niels Bohr Re: HWND typecast ? Thomas Andersen18-Mar-02 21:41 Thomas Andersen 18-Mar-02 21:41  Ahhh... Thank you very much.... I'll give it a try ASAP /Thomas Re: HWND typecast ? alex.barylski18-Mar-02 22:00 alex.barylski 18-Mar-02 22:00  Why does the caller have to use LPCSTR...? One is a pointer to a string of char's and the other is a windows handle...the conversion should work and it should compile, but your app might act funny... Cheers! "An expert is someone who has made all the mistakes in his or her field" - Niels Bohr Re: HWND typecast ? Thomas Andersen18-Mar-02 22:15 Thomas Andersen 18-Mar-02 22:15  The thing is that the calling application is made with a casetool called Cool:Gen and it is not very good at using OLE/ActiveX or other external functions.. So after I have made my DLL and try to call it Cool:Gen will only allow me to specify a text variable (LPCSTR) as output. Thus when passing a date that too wil have to be converted to an LPCSTR before making the call. The casetool is point and click so I'm just presented with a list of available choices. /Thomas Re: HWND typecast ? alex.barylski19-Mar-02 10:01 alex.barylski 19-Mar-02 10:01  Ahhh! I see...although I have never used a case tool I think I know what they are... RAD utility...? Like VB but easier...? Ok dokie... Cheers! "An expert is someone who has made all the mistakes in his or her field" - Niels Bohr Re: HWND typecast ? Thomas Andersen20-Mar-02 3:41 Thomas Andersen 20-Mar-02 3:41  Actually Cool:Gen is so restrictive that the only thing you type are descriptions and if necessary the contents of a hardcoded textstring.. All the rest is donew by clicking with the mouse and in theory it's impossible to make invalid code.. (works app. 95% of the time, if you are not trying anything to fancy like using OLE or ActiveX objects ) based on what ou just cliked on you are presented with a selection of valid arguments/variables you can use.. It's a rather complex tool containing both datamodelling, Database s tructure and documentation. Besides that it can generate both C, Cobol java and ASP/COM and several other languages to sevaral DBMS'es based on the same code you clicked in.. Very highlevel language.. Compared to it VB would be like assembler.. The price for this is that you are very limited in what your code can do.. BTW: I tried you code and I found that I had to use atol on my LPCSTR and then use HWND = (HWND) long .. But I wouldn't have made it without your help... /Thomas CBitmapButton & LoadImage (help) kvgraphiti18-Mar-02 20:49 kvgraphiti 18-Mar-02 20:49  I'm trying to set up an application that uses MFC's CBitmapButton. I've managed to get them to work provided that the bitmaps are already present within the resources available to the application. What I would like to do is give the users the oppurtunity to customize the look of the app by allowing them to change the images that the CBitmapButtons use to one of their own images and have the change done at runtime. I've managed to load a bitmap from a file using the LoadImage() function, which returns a handle that can be casted into a HBITMAP. What I'm stuck on is how to take that HBITMAP and tie it into the CBitmapButton, . The CBitmapButton::LoadBitmaps member function takes only two types of paramaters a "LPCTSTR lpszBitmapResource" or a "UINT nIDBitmapResource". Is there a way to cast an HBITMAP or a CBitmap into a datatype that the CBitmapButton::LoadBitmaps function will take? Thanks for you help.

You wil get peoples opinions. Mine personally....start with SDK understand that, then move into MFC. First and foremost learn C++ if you don't already know it. I guess it depends on what your trying to accomplish...do you plan on making q & d type DB apps or really cool looking GUI's...? Cheers!

What kind of application would you like to create? Once you figure that out then ask what tools and languages you should learn to create those applications.

Disabled edit control with colored text Jack Handy18-Mar-02 18:46 Jack Handy 18-Mar-02 18:46  I have a multiline edit control on a dialog and I disable it with EnableWindow(FALSE). My problem is that I want the text to be a different color but it stays the grayed out disabled color. I would be open to not disabling the box but that would give me three additional problems. a) I'd have to make sure it could never get focus, b) I'd have to change the mouse cursor from the I-beam to the arrow, and c) I'd have to make sure text couldn't be selected. Any Suggestions are welcomed -Jack
