C# MDI form Drawing Member 189349022-Jul-05 3:19 Member 1893490 22-Jul-05 3:19  Hello , I wanted to know how u draw lines on a MDI form in C# to display four quadrants on the screen override enable property fady_sayegh22-Jul-05 2:09 fady_sayegh 22-Jul-05 2:09  hi to all, how can i disable a text box without changing the forecolor to gray. what i want is to disable the text box and to keep the forecolor to black. i don't want to use the readonly property because the back color is still white. best regards and thanks in advance fady Re: override enable property Dave Kreskowiak22-Jul-05 4:57 Dave Kreskowiak 22-Jul-05 4:57  Those are your only options while still using a TextBox. A little trick I've seen used before is to create equivilent label controls, set them up to look like the textboxes, and put them behind their textbox counterparts. Then when the textboxes needed to become ReadOnly without the readonly look, they just set the TextBox.Visible property to false.

Re: Virtual Memory Vasudevan Deepak Kumar22-Jul-05 1:43 Vasudevan Deepak Kumar 22-Jul-05 1:43  Hi: I think this is purely controlled by Windows and may be a little by CLR. I don't think there would be a setting to this effect.

Re: Virtual Memory Vasudevan Deepak Kumar22-Jul-05 3:48 Vasudevan Deepak Kumar 22-Jul-05 3:48  Perhaps yes. But within CLR's realm and through C#, it may not be, since all Memory Management is purely controlled by CLR. You may need to venture out into direct C++ programming and delve into Windows APIs for that. Is'nt it?

You'll have to write your app in unmanaged C++ to get this to work.

Outlook multiple profiles angeltsoi22-Jul-05 0:56 angeltsoi 22-Jul-05 0:56  Hi all, I would like to know is it possible to switch between mulitple profiles within the same application? I have a problem that once I logon a profile, I find no means to switch to another profile. I have tried to use logoff method but it fails, it still stays with the original profile. Owner drawn text box Bravid22-Jul-05 0:47 Bravid 22-Jul-05 0:47  Hello I'd like to have a text box that I can selectively put a little red triangle in the top right corner of, pretty much in the same way excel does when you have comments on a cell. I had a look at handling the Paint event for the text box but it doesn't seem to be getting fired. Is there something more than assigning my own handler function to the paint event delegate to achieve this? I haven't inherited from the text box control, could this be the problem? BTW If it's not obvious I'm pretty new to .NET Cheers David Re: Owner drawn text box Rob Graham23-Jul-05 17:31 Rob Graham 23-Jul-05 17:31  You may need to set the textboxes ControlStyles.UserPaint style bit (Texbox1.SetStyle( ControlStyles.UserPaint)) in order for the paint event to fire. If you plan on having several of these, it might be worthwhile to create your own by subclassing (inheriting from) it, so that you dont have to repeat a lot of code.

Edmund Burke Re: Owner drawn text box Bravid26-Jul-05 1:44 Bravid 26-Jul-05 1:44  Hello Rob Thank you for your answer. I've been looking for a property or something, and now it looks like I've found it...with your help of course The main reason I didn't want to inherit from the text box is that I want to implement this feature as a kind of decorator that I can use on a selection of controls. I'm creating a control manager that will create the controls dynamically, and a "state" manager that will manage standardised sets of functionality based on what the user is doing e.g double click on a text box to display a window containing a list of values. Having the red triangle...or any other visual cue, will be the indicator to the user that they can double click to get the window. I'm not adverse to inheriting controls, but if possible, I'd rather stick to standard controls and manipulate them wherever possible. Do you think I'm approaching this in the right way?

What version of the Oracle CLIENT is installed on your machine? It would appear that you don't have the proper Oracle Client installed on the machine to connect to the server.
