FlexGrid Activation Problem glerner26-Jan-00 16:58 glerner 26-Jan-00 16:58  Hi, I have a embedded FlexGrid control on a dialog box and I have distributed MSFLXGRD.OCX and registered it in the production machine. It was working fine and then all of a sudden it stopped working (the control doesn't load). I think it has to do with licensing of controls, but I thought embedded controls have license keys stored in the executable code. What could have went wrong and how can I fix this problem? Thanks. Glenn Nested CSplitterWnd('s) and CSize Frank Deo25-Jan-00 11:01 Frank Deo 25-Jan-00 11:01  Can someone explain to me how to get the Panes of a nested splitter window to size up correctly? I know that I should know this, but I can't figure it out. My splitter is 2 rows. Nested in the 1st row is 2 columns. So, three views. |---------| | | | | | | ----------- | | ----------- ^bad graphic. The 2nd row always takes up the whole client area of the window. The nested portion is correct, once you drag the splitter bar down. Any explanation of how to do this would be great. Thanks, and sorry for the dumb question. Frank RE: Nested CSplitterWnd('s) and CSize Mike Dunn25-Jan-00 14:50 Mike Dunn 25-Jan-00 14:50  You set the initial size for each view in the splitter in the call to CSplitterWnd::CreateView(). For starters, try always passing a size of, say, 100x100. Then experiment with the numbers until you get the look you want. --Mike-- ================== The original message was: Can someone explain to me how to get the Panes of a nested splitter window to size up correctly?

CSplitterWnd::SetRowInfo(int row, int cyIdeal, int cyMin ); It worked. Thanks!

Frank Need a SMALL database solution Ryan Schneider25-Jan-00 7:12 Ryan Schneider 25-Jan-00 7:12  Can anyone suggest a SMALL databsase solution, where the runtime needed is on the order of 100-200k rather than 1-7 meg like ADO or Jet. Doesn't need to be full featured, just small. Thanks, Ryan Schneider NeoWorx Inc.

Closing a CFormView Jed24-Jan-00 5:59 Jed 24-Jan-00 5:59  Hi !!! In my MDI App, if the user close a child window (derived from CFormView)by clicking on the top right cross button (X), I would like my program to ask him if he is sure or not. How could I do that ?

When I want to write some classes to display a menubar like VC IDE, I encountered a problem about drawing system items, the three buttons ,icon and system menu which is originally on the child window caption bar.When the child window is maximized, I have to draw them on my menubar, the icon and menu is easy to draw, but how about the three buttons on right.

Layered Window Impl on 98 Eric Crahen21-Jan-00 16:01 Eric Crahen 21-Jan-00 16:01  I have seen several apps on Win98 that use softshape's ActiveSkin ActiveX control. Mostly this control allows people to haev a coherent means for creating skinned 'applications'. It includes one function that allows you to set a transparency level. If you download the control right from softshape you can use the Visual Studio tools to view the interfaces their control provides. There is an app called BoxCard @ http://softini.cjb.net that uses this feature and will let you see it in action I've tried several things briefly to try and implement some transluceny. It is pretty easy to make a translucent menu or dialog as long as it is WITHIN a frame window or something. You can just make owner draw controls that get the parentdc and alphablend the control DC with the parents. This works really well if you have a stable bitmap background. However, this become very hard to do when you have other windows moving around behind a translucent control or you try to do this on the windows desktop. Win2K provides a LayeredWindow to help with this. Does anyone have access to a W2K dev kit that contains this implementation? I check my VC 6 for this but it does not seem to be included. I'd like to see how they did this. I also considered it might be possible to control how windows draws the window, after all - doing this can't befar off from what programs like eFX and WindowBlinds have been doing to change the frame bars on existing windows already. - Eric Any suggestions? I plan on putting all this info together with some other controls I've made and putting it up on the web with source. MFc is nice, but its really easy to think of semi-simple things that are very diffculut to do - like change an image on a static control (w/o hiding an existing one and displaying a new control) Anyways, I'm getting off on a tangent. Please let me know you thoughts or tips. - Eric crahen@buffalo.edu DrCrahen@mad.scientist.com Layered Window Impl on 98 Eric Crahen21-Jan-00 16:01 Eric Crahen 21-Jan-00 16:01  I have seen several apps on Win98 that use softshape's ActiveSkin ActiveX control.

Dialogs with ActiveX controls in MFC regular dlls Anonymous20-Jan-00 16:41 Anonymous 20-Jan-00 16:41  I've been developing an MFC regular dll which exports a function which creates and displays a dialog. Everytthing works fine. However I get a problem when I insert an Active -X control (eg: MS-Chart control) at design time and then display the dialog. In this case when I call my exported function the dialog is not displayed at all, and I noticed one thing DoModal returns IDCANCEL. What do I do to solve this problem. Thanks, Anyhelp would be highly appreciated.

Regular dll & Active X control in a dialog Anonymous25-Jan-00 1:08 Anonymous 25-Jan-00 1:08  Actually the client part of the code creates an MFC worker thread which calls my exportred function. I found a KB article in MSDN which said that I need to call OleInitialize(0) from my client. I did that also, but the dialog is still not displayed. Any ideas ? Here is the pseudo-code, UINT Thread Proc(LPVOID ) { //exported function from regular dll which //has a dialog with a Registered Active-X control ShowDlg(); return 0; } void CMainFrame::OnViewTest() { AfxBeginThread(x,y); } The thing works fine if there is no thread involved. ================== The original message was: Did you call AfxOleInit() and AfxEnableControlContainer() ? ================== The original message was: I've been developing an MFC regular dll which exports a function which creates and displays a dialog.
