Draw Shape To Screen Anonymous7-Jun-04 21:40 Anonymous 7-Jun-04 21:40  hi why this code dosnt work. <br /> Graphics g = Graphics.FromHwnd(IntPtr.Zero);<br /> g.DrawLine(new Pen(Color.Red),50,50,500,500);<br /> g.FillRectangle(new SolidBrush(Color.Red),10,10,250,300);<br /> thanks MDI Form kobystud7-Jun-04 21:20 kobystud 7-Jun-04 21:20  hello, i have created a MDI form that contain two child forms class ParentForm : Sytem.Windows.Forms.Form { ........ void func() { this.IsMdiContains = true ChildForm1 child1 = new ChildForm1(); child1.MdiParent = this; child1.Show(); ChildForm2 child2 = new ChildForm2(); child2.MdiParent = this; child2.Show(); } my question is : i want to show both child1 and child2 and i`m using the next statement: this.LayoutMdi(System.Windows.Forms.MdiLayout.TileHorizontal); but the problem is that i dont want to see on the screen half from ChildForm1 and half from ChildForm2. i want to see the real size form definition of both Child forms. what should i do? thank you koby Re: MDI Form Dave Kreskowiak8-Jun-04 3:13 Dave Kreskowiak 8-Jun-04 3:13  You could try MdiLayout.Cascade instead and see if that layout works for you. If not, then you'll have to write your own code for laying out the child forms the way you want.

Question abt Service SatyaDY7-Jun-04 20:14 SatyaDY 7-Jun-04 20:14  Hi, I am trying find the services which are running on my machine on polling basis, and I am trying write this to a file before shutdown. I am trying to do this using a service, I am writing the code for file writing in the OnStop() method of the service. The problem is my service starts and stops immediately. Why this is happening?? Code Snippet: OnStop() { System.IO.StreamWriter file = new System.IO.StreamWriter("d:\\test.txt"); Process [] curentProcess= Process.GetProcesses(); foreach(Process p in curentProcess) file.WriteLine(p.ProcessName); file.Close(); } Regards, Satya Re: Question abt Service Corinna John7-Jun-04 20:34 Corinna John 7-Jun-04 20:34  SatyaDY wrote: my service starts and stops immediately Your service does not even reach OnStop(), the problem is Main() or in OnStart(). To locate the failure, check the event log. Are there any exception messages from your service? If not, you can write a log file during OnStart(), to see where the service stops. Re: Question abt Service SatyaDY7-Jun-04 21:49 SatyaDY 7-Jun-04 21:49  check the event log Yeah, I checked the event log, it's having entries for start and stop. When I comment the code, for file opening and writing, I find it running without any problem. How the file writing of the process names giving the problem I couldn't get. Regards, Satya Re: Question abt Service Nick Seng7-Jun-04 21:24 Nick Seng 7-Jun-04 21:24  ummm... I don't really have a solution to your problem, but I think I see a problem with your service. Basically, in order for your service to work, it has to be the first service to stopped during shutdown, else the GetProcess Method won't return those processes stopped before hand.

Because the GetProcess couldn't get the Processes, file writing is also failing and the service is stopping immediately. Can we give priority (for making it first to stop)?? Regards, Satya Re: Question abt Service Nick Seng7-Jun-04 22:05 Nick Seng 7-Jun-04 22:05  I'm not too familiar with services, but you might try and see doing this Thread th = Thread.CurrentThread; th.Priority = ThreadPriority.Highest; during onStart if it will help.

Re: Question abt Service Dave Kreskowiak8-Jun-04 3:07 Dave Kreskowiak 8-Jun-04 3:07  Whoa there Tex! Really bad idea. This will not give priority to the service to be shutdown first. As a matter of fact, you'll just end up slowing down the rest of the system doing this... You can't give priority to any service to shutdown first. You might want to try overriding WndProc and watching for the WM_QUERYENDSESSION message.

Change Window Title Form Font Anonymous7-Jun-04 20:06 Anonymous 7-Jun-04 20:06  hi all when change font property in windows forms, dont change font title of form,Why. how resolve it. thanks, Re: Change Window Title Form Font Heath Stewart8-Jun-04 3:44 Heath Stewart 8-Jun-04 3:44  Because the window caption font is set by the Display settings on your machine. It is a non-client area. You can set fonts in your client-area. It is possible set the font in a caption but there is no functionality to do this in the .NET FCL. You have to override WndProc for your main Form and handle the WM_NCPAINT message, for example, to have a different font than what the user preferences specify for a window caption font. If you search CodeProject, there should be a few articles on non-client painting.   Microsoft MVP, Visual C# My Articles Re: Change Window Title Form Font Aaron Eldreth8-Jun-04 3:54 Aaron Eldreth 8-Jun-04 3:54  Heath, you really don't like it when people don't search CP or Google before asking questions on the message boards, do you?

Hardy Re: Change Window Title Form Font Heath Stewart8-Jun-04 4:06 Heath Stewart 8-Jun-04 4:06  People that can't research they own simple problems do not belong in this field, IMO. Asking questions like "What does this method do?" is stupid - consult the documentation for that method. If you still don't understand it - fine - then ask about it. That doesn't really apply to this guy, though. Read me response a little more carefully. I told him what the problem was and asked him to search CodeProject. There are articles about this, so why should I waste my time typing a bunch of code that's already been written. I actually have some example code dealing with non-client painting in this forum that pre-date said articles that I've seen (good and bad articles) alike. Asking him to search here is merely a way to save time and typing. He didn't even know what to search for before; now he does.   Microsoft MVP, Visual C# My Articles Re: Change Window Title Form Font Dave Kreskowiak8-Jun-04 4:10 Dave Kreskowiak 8-Jun-04 4:10  I know I don't like it. What's wrong with going to MSDN and searching for classname class .net Bam! Everything you wanted to know about the class... If you want to write code for a living or just be semi-good in the IT Industry, you absolutely have to posses the skills to do research and teach yourself! What good are you to your company if you can't research an answer to a support question or learn new design/coding techniques? I come here to answer as many questions I can and learn during the process. Mostly, I read questions and if I already know the answer, post it. Otherwise, it's off to MSDN i go, do a little research, then post come back and an answer. But, after that, I'll watch for the answers that Heath posts so I can learn the finer points from him and see where I went wrong! He's corrected me on a bunch of occasions, and I don't have any problem with that all! I actually look forward to it. It's all part of the learning process...

Hardy DatView DataBinding using Parent relation Corneliu Tusnea7-Jun-04 15:32 Corneliu Tusnea 7-Jun-04 15:32  Hi, I'm trying to create a DataBinding of a text box to via a DataView by using a parent relation not a child relation: eg: (the classical) Customers-Orders relation. I have a DataView on the Orders Table (for very good reasons it's impossible to set the DataView to the Customers Table). Now, I want to set a text box to the value of: Orders.Customers2Orders.CustomerName .. or something like that. If I do: textbox1.DataBindings.Add ( "Text", dataView1, "Customers2Orders.CustomerName" ) I get a nice: {"Cannot create a child list for field Customers2Orders." } System.SystemException: {"Cannot create a child list for field Customers2Orders."} m_paramName: null Message: "Cannot create a child list for field Customers2Orders." ParamName: null Is this possible somehow ? Maybe by implementing my own Binding object? Thanks alot, Tutu. Creating Financial Chart control using C# sgeesala7-Jun-04 15:06 sgeesala 7-Jun-04 15:06  Hi, Any one knows about how to implement chart control(financial related). please help me out how to go about it. thanks gs Re: Creating Financial Chart control using C# Dave Kreskowiak7-Jun-04 15:47 Dave Kreskowiak 7-Jun-04 15:47  Your first step is to layout EXACTLY what you want your control to do. What type of data is your control going to need? How is this data going to be stored so that it is accessible by the client app and still quickly usuable by your control? How is the data going to be passed to the control? Do you want to implement databinding? Are there other standard controls that come close to the functionality you need (probably not in your case!)? Now, what do you want your control to look like? What graph types do you want to support? Do you want to add axis labels? How about automatic range scaling? What do you want to happen when the control is resized? Do you want to support horizontal scrolling? Now, after all that, you can start designing your control. The painting code, by itself, is going to depend on answers to ALL of those questions. It may seem like alot, and it is!, but a control like this is nothing less than a full application written to do a very specific task. RageInTheMachine9532 "...a pungent, ghastly, stinky piece of cheese!" -- The Roaming Gnome Re: Creating Financial Chart control using C# Heath Stewart8-Jun-04 3:39 Heath Stewart 8-Jun-04 3:39  To add to what Dave said, there's lots of examples here on CodeProject.Just search for chart controls in C#. There everything from line graphs to bar graphs. For anything else, you really need to know the math behind it. As Dave said, this is a big task. I recommend you just get a third-party control like ChartFX from Software FX[^]. It's cheap and full-featured. You'll spend a lot more in man hours than what it costs for this develop-licensed, royalty-free product, especially if you don't even have an idea of where to start!   Microsoft MVP, Visual C# My Articles File sharing query benglish727-Jun-04 14:49 benglish72 7-Jun-04 14:49  Hi, I'm writing a program that attempts to open a file stream using FileInfo.OpenRead(), this seems to fail when another application is accessing the same file. As I need to be able to read this file whilst another has it open or access it, is there anyway I can get it to open instead of throwing IOException in C#? Thanks. Here's a code snippet //check file exists System.IO.FileInfo info = new System.IO.FileInfo(sFileName); if(info!=null&&info.Exists==true) { //ok, file exits, lets read it in... try { System.IO.Stream stream = info.OpenRead(); //do stuff here stream.Close(); } catch(IOException exception) { }
