• Visual C++ Getting garbage setting dialog box text

  Hi Folks; I'm trying to set the text of a dialog box with SetDlgItemText. As an example I'm trying: SetDlgItemText(hwnd, IDC_F1, "Some text"); where IDC_F1 is defined as the ID for an edit box. What I'm getting is just garbage and I thought maybe it was my font but I've set it do Courier New, size 8 which I thought was pretty standard. Maybe someone could shed some light on my sitation. Do you need Unicode for other parts of your software, e.g. localization If not, you can simply switch your project to build for multibyte, and continue to use the char CompName with SetDlgItemText , without any conversion. To do this, go to Project > Properties (bottom item) > Configuration properties > General , and swi ...Show All

• .NET Development Oracle Float data type in .Net

  I ran into the following issue and wondering whether or not any body has an explanation for it. A value of 8.45 is stored in a FLOAT data type column in the exact same schema on two different databases. While it is retrieved (thru OracleDataAdapter) and displayed, the same client showed 8.45 from one database and 8.499999999999 from other database. Keep in mind that the same .NET code, schema (two different databases) with the same data is used here. After I altered the data type from FLOAT to NUMBER, without defining any precision or scale, issue is resolved and 8.45 is always returned and shown when pointing to either database. Does the FLOAT data type is the cause of this problem Any help is greatly appreciated. ...Show All

• Windows Forms Put a glass panel over form while processing?

  Dear all What i would like to achieve is placing something like a glass panel over the form while is doing some processing and show a proress bar. Little something like that , which would informa the user that something is happening:) Any ideas or advice Is there any code examples Cheers theblueeyz wrote: Oh, I know that it's not meant as an interactive control. What I meant was, the first time I make it visible, I clearly redraws itself about 5 or 6 times before it settles down. After that, subsequent Visible = true calls are fine. It seems to have alot to do with the alpha blending. The lower the alpha, the greater its apparent need to redraw. I don't see Flickering, but I do see an obvious Paint ...Show All

• Windows Forms Include the parent control when a child is cut / copied and pasted.

  Hi all, This is the final step in what became a rather involved process. The big picture is that I need to present a container control at design-time which does NOT clip its children. So yeah, I want for instance a child button control to be able to draw beyond its parent's bounds. I've gotten it to work by implementing an "envelope / hub" mechanism, where the hub is the above-mentioned container, and the envelope is its parent, another container which sizes itself to envelop the hub. When the user needs to "float" (ie. un-clip) the child button, it gets re-parented to the envelope and now has free reign to paint over the hub's bounds. All that to say, I have one final problem: when the hub is cut to clipboard, ...Show All

• .NET Development Site License protection schemes, defeating Reflector?

  I am invovled in the development of a programmer tool written in asp.net 2.0. My company is interested in securing this tool via an encrypted license file. However, we realize that anyone using Reflector could easily crack our protection. One way around this would be to make extensive use of web services, but this is not an acceptable solution for us. Would using unmanaged code to perform some core functionality solve this problem The unmanaged could could check the encrypted license file and when decompiled, it would not be as insecure as decompiled managed code. Has anyone done this Is the theory sound Native, unmanaged code is the only way to provide equal security to Win32 binaries. Obfu ...Show All

• Visual C# Interfaces oversold???

  First, I must admit that I am a C# novice and so I probably don’t have as much knowledge and experience on the subject of interface as most of you guys reading this post. After reading a few books on C# and interface design, I still can’t see and understand the real power of interface unless of course, we are talking about interfaces as a powerful concept in OOP ‘only’ and not as a powerful concept in the general sense. When I was first learning OOP I was quite suspicious about the ‘excellent features’ that OOP claims to be able to deliver to the world and I was right. For example, in reality OOP offers very little if any, code reuse. I am now having the same suspicion about interfaces even though I see a lot nice words used to d ...Show All
