Newbie Need Help : Set font color, style, etc... 22-May-02 6:13 22-May-02 6:13  I am an extreme newbie to C++! I am using CreateWindow() to create a window, and it is successful, but I can not find a way to set the window's font size, style, etc... Is there a simple way to do this or am I missing something completely? All help is extremely appreciated!!! Sample: m_hWnd = ::CreateWindow(TEXT("EDIT"), TEXT("My Text"), WS_CHILD | ES_LEFT | WS_VISIBLE | SS_LEFT, rect.left, rect.top, rect.right - rect.left, rect.bottom - rect.top, m_hWndParent, NULL, NULL, NULL); Thanks, Troy troygtroy@hotmail.com Re: Newbie Need Help : Set font color, style, etc... Jason Henderson22-May-02 6:18 Jason Henderson 22-May-02 6:18  To change a window's font, you will have to get the device context using GetDC(), then create a font (look up CreateFont), then call SelectObject() to select the font. Be sure to call DeleteObject() when you are finished with the font, and ReleaseDC() when you no longer need the device context. Documentation for these functions can be found on MSDN. Like it or not, I'm right. Re: Newbie Need Help : Set font color, style, etc... 22-May-02 6:18 22-May-02 6:18  Geez, out with vb's Me.Font = "" and into a whole new world. Thanks for the help and for the quick response. I will follow your lead in MSDN. Thanks again, Troy VC++ and Database Shayna22-May-02 5:36 Shayna 22-May-02 5:36  Hi, everyone I am trying to develop some code to connect my local MS Access database. Now I have a very long char string, the length of this string could vary very differently. In my Access database, the field type is Memo. Now I am using ODBC function SQLBindParamenter to try to bind this string dynamically. My question is how should I set the columnsize parameter of the SQLBindParamenter method? I can always set a very huge number, like 50000, but the length of that string still could be larger. what should I do? Anyone has any suggestions? Thanks a lot in advance. CSpinButtonCtrl Rage22-May-02 4:53 Rage 22-May-02 4:53  Hi ! Anyone knows about a tutorial where I could learn how to use CSpinButtonCtrl ? Well, admit I have a MFC App with a CEdit and a CSpin.. next to it. How do I assign the CEdit as the buddy window for the CSpin ? My question could be : how do you retrieve the Cwnd * from a given control ? Thanks RaGe Re: CSpinButtonCtrl Rage22-May-02 5:15 Rage 22-May-02 5:15  Well, I got it alone =) CWnd *tmp=GetDlgItem(IDC_EDIT); m_Spin.SetBuddy(tmp); in case other are interested ... RaGe Unfortunately, brute-force solutions tend to be slow even when performed by modern-day microcomputers, which are capable of several MIPS except when I'm late for an appointment and want to finish a compile and run just one more test before I leave, in which case the crystal in my computer is apparently designed to automatically revert to 1 Hz. -- Michael Abrash Re: CSpinButtonCtrl Alex Cramer22-May-02 16:46 Alex Cramer 22-May-02 16:46  Just place Spin near edit in the dialog editor, invoke "Layout->Tab Order" menu command, and set spin tab number after edit tab number. Then select "AutoBuddy" property of spin and it will be automatically attached to edit control. In OnInitDilog function set the spin behavior, for example: <br /> CSpinButtonCtrl* pSpin = (CSpinButtonCtrl*) GetDlgItem(IDC_FREQ_SPIN);<br /> pSpin->SetRange(0, 20000);<br /> Re: CSpinButtonCtrl Michael Dunn22-May-02 19:11 Michael Dunn 22-May-02 19:11  Sorry to nitpick, but the proximity of the two controls is meaningless. Only the tab order is important. Having them near each other makes the dialog easier to understand and maintain, but has no effect on functionality. --Mike-- Just released - RightClick-Encrypt - Adds fast & easy file encryption to Explorer Like the Google toolbar?

I need to display a dialog box built in resource editor at a certain precise coordinate on screen. Is there anyway I can achive this without modifying the resource .RC file.

Rage22-May-02 4:58 Rage 22-May-02 4:58  Try a MoveWindow() (you can even resize your dialog with this one) like this : MoveWindow(x,y,DialogSizex,DialogSizey,TRUE); where x and y are your coordinates, DialogSizex the width and DialogSizey the height of your window.

Renjith Ramachandran22-May-02 7:11 Renjith Ramachandran 22-May-02 7:11  hi friend i always prefer SetWindowHandle()API..BCzthat i sthe simple and traditional way to locate the window the way must use SetWindowPos( HWND hWnd, // handle to window HWND hWndInsertAfter, // placement-order handle int X, // horizontal position int Y, // vertical position int cx, // width int cy, // height UINT uFlags // window-positioning options ) i think ur doubt is about the second parameter hWndInsertAfter here just put HWND_TOPMOST which Places the window above all non-topmost windows The TRUE CP -ian Re: Dialog Box Precise Location. Michael Dunn22-May-02 19:13 Michael Dunn 22-May-02 19:13  In your WM_INITDIALOG handler, call SetWindowPos() and pass the x,y values you want the dialog to appear in. (Note that in MFC, you cannot use (0,0) since that is the default location and MFC will call CenterWindow() for you. Using any other position overrides this behavior.) --Mike-- Just released - RightClick-Encrypt - Adds fast & easy file encryption to Explorer Like the Google toolbar?

Michael Memory Leaks JohnnyG22-May-02 4:30 JohnnyG 22-May-02 4:30  The VC debugger is reporting memory leaks but not giving me source file name or line numbers as outlined in the following MSDN article for DumpAllObjects: <url>http://msdn.microsoft.com/library/en-us/vccore98/HTML/_core_dumping_all_objects.asp As you notice the example displays filename and line number where the leak occured. I have been trying all kinds of things but cannot get it to display this way (in debug window, file, or console window). I only get: Dumping objects -> {372970} normal block at 0x0242AEB8, 8 bytes long. Data: < xL > 08 78 4C 10 01 00 00 00 and more like it. I have been using CMemoryState objects and _CrtSetReportMode, _CrtSetReportFile, etc. I have put all of that code in the main() function hoping it will catch all errors in all other modules. Does anyone know how to do this and/or have an example????? TIA. Re: Memory Leaks Chris Losinger22-May-02 4:44 Chris Losinger 22-May-02 4:44  see that first number? that's the allocation number. put this at the very beginning of your app: _crtBreakAlloc = 372970; you'll get an assertion when that allocation happens. back up the call stack and there you go... the only trick is to make sure you run the app exactly the same way - since you're breaking on the Nth memory allocation. if you change the allocation order even by one, you'll be lost. -c Cheap oil.
