It's far from perfect, but it's *way* farther than that from RC.EXE! It's true, you still can't "see" what's in a RES once compiled, but the names and IDs are there, and editable. I suppose I lean towards them, anyway, because I frequently store larger text blocks (of the sort displayed for Usage in a console app, for example) and stuff like that. Plus, you can't mark an app "Unattended" if there's even one form in it, right? -- Working without a .NET? http://classicvb.org/

God! How I hate that phrase, "did not work"! What was it about the graphics that "did not work"? You need to be specific. Without more details from you I can only assume that some of the graphics you tried did not produce transparency of the User Control in areas where the graphic was white. If that is the case then the area probably wasn't white at all, but merely "looked white". The areas that you wish to be transparent need to be *exactly* the same colour as your User Control's MaskColor property (white in the case of the specific example I posted). Most jpg picture files for example can contain a dozen or more completely different "non white" pixel colours in an area that to the naked eye looks like solid white. That is why I said you should use bitmaps. > In any case, I have a graphic that has a transparent background. > This is less of a problem than what I was trying.

My Click sub did nothing. Can you help? Just place your User Control directly onto the Form in the usual way. If you then double click it on the Form (in the VB IDE) you will see that it has only a limited number of Events (typically DragDrop, DragOver, GotFocus, LostFocus and Validate, although this may be different on different systems). To get a Click event , for example, you need to add one. You can call the events you add by any name you want. You can add an event in the following manner: Create your User Control (Project / Add User Control) and set its Picture, MaskPicture, MaskColor and BackStyle properties in the way previously described. Then double click the User Control to open up the User Control's code window and paste in the following code (making sure it replaces any code that VB may have already placed there for you): Option Explicit Public Event SomebodyClickedMe() Private Sub UserControl_MouseUp(Button As Integer, _ Shift As Integer, X As Single, Y As Single) RaiseEvent SomebodyClickedMe End Sub Now close the user Control's design window as previously described. You will now see the User Control in the list of available controls. Add one to your Form in the usual way. Now double click the User Control on your Form and you'll see that in addition to the previously mentioned events it now has another even called "SomebodyClickedMe". You can use that event in your VB Form in the same way that you would use any other event. For example: Private Sub UserControl11_SomebodyClickedMe() Me.Caption = Val(Me.Caption) + 1 End Sub Mike

For example: > > Private Sub UserControl11_SomebodyClickedMe() > Me.Caption = Val(Me.Caption) + 1 > End Sub > > Mike You are correct "... did not work." is a terrible phrase when one is attempting to explain a problem. You did get it correct that the transparency did not happen in the process. I will double check the white background on those GIFs which did not produce a transparent background. The only written information that I have found in my texts describing the UserControl show the same text box example. I appreciate your help. Thank you, Jim |
