Re: avoiding double invoking Stephan Wright11-Aug-04 7:53 Stephan Wright 11-Aug-04 7:53  I managed to do what you recommended, well almost! I hardcoded the parameters for FindWindow, because I thought it would be the same verytime I start my application. But I found out it isn'T, the first parameter for example changes everytime I do restart the computer. And besides it's something really strange. I thought my Window was a Form but well there were numbers and other numeric or letters. So I will have to change this to reading or receiving this from the application, but where? Maybe I don't see the wood because of all the trees anymore but I guess I am stuck again. I was able to get the Handle, the hashvalue or whatever but not the Classname of my Form. Well the WindowName isn't the Problem because it's stored in the Form1.Name element and I just have to fetch this. But where do I have to fetch the first parameter from? Could you or anyone else help me please, to automate it so I could remove the hardcoded thing! Thanks! Stephan.

This assumes you know the name of the window text. There are other methods of getting the window HWND (Handle) however if you are writing the application you should know this (more than likely). Does that make more sense? - Nick Parker My Blog | My Articles Re: avoiding double invoking Stephan Wright11-Aug-04 20:59 Stephan Wright 11-Aug-04 20:59  Well, as I said before I should be able to get the name of the window with the Form1.Name field. What I wanted to do is trying to get the classname for my window. Because it is something like WindowsForms10.Window.8.app88 and that's what I do not want to hardcode because this changes everytime I reboot my PC. It could be WindowsForms10.Window.8.appdd as well. With "second instance" I ment the user shouldn't be able to invoke the same application on the same PC twice, e.g. by clicking twice on the button. If he does the running application should reappear. So because it's the same application (but just a second instance) the classname has to be the same. So the second invokation would have the same classname (prooved via Spy++) so I should be able to get the classname from somewhere. But I am not sure where to fetch it. I also have a mutex on the instance, maybe I could fetch the Handle from there if it is possible to use it in this context. Stephan. Re: avoiding double invoking Anonymous12-Aug-04 2:05 Anonymous 12-Aug-04 2:05  what about if you just do the following: add the handle hash in the registry and evey other application will be able to check it. And if it matches then the application is running. Or if the value is set, then the application is running. But do not forget to reset the value, because otherwise you won't know if there is an application running or not! install AddIn in VS.NET2003 nthevu10-Aug-04 3:08 nthevu 10-Aug-04 3:08  i downloaded and install project GotoFunction, and after i recompile source code and build new setup project for addin GotoFunction, the install package doesn't work.

Unfortunately i forgot to post the answer here. So Here is the answer for " How we will change the color(caption color) of a Tabpage. Who is going to draw ? Tabcontrol have a properties called DrawMode. This will set or get the value that whether user or system will paint the caption.By default it is normal. Means system(OS) will paint the caption for you. If you(parent form) want to draw the caption you have to set the value of the property to OwnerDrawFixed. You can mention DrawMode on design time or runtime like below mentioned code. this.tabControl1.DrawMode = System.Windows.Forms.TabDrawMode.OwnerDrawFixed; Now you mention who is going to draw the caption. Next thing is how is going draw ? Tab control have an event called DrawItem event which will occure when ever an area need to be painted. eg: this.tabControl1.DrawItem += new DrawItemEventHandler(this.tabControl1_DrawItem); private void tabControl1_DrawItem(object sender, System.Windows.Forms.DrawItemEventArgs e) { Font f; Brush backBrush; Brush foreBrush; if(e.Index == this.tabControl1.SelectedIndex) { f = new Font(e.Font, FontStyle.Bold | FontStyle.Bold); backBrush = new System.Drawing.Drawing2D.LinearGradientBrush(e.Bounds, Color.Blue, Color.Gold, System.Drawing.Drawing2D.LinearGradientMode.Vertical); foreBrush = Brushes.White; } else { f = e.Font; backBrush = new SolidBrush(e.BackColor); foreBrush = new SolidBrush(e.ForeColor); } string tabName = this.tabControl1.TabPages[e.Index].Text; StringFormat sf = new StringFormat(); sf.Alignment = StringAlignment.Center; e.Graphics.FillRectangle(backBrush, e.Bounds); Rectangle r = e.Bounds; r = new Rectangle(r.X, r.Y + 3, r.Width, r.Height - 3); e.Graphics.DrawString(tabName, f, foreBrush, r, sf); sf.Dispose(); if(e.Index == this.tabControl1.SelectedIndex) { f.Dispose(); backBrush.Dispose(); } else { backBrush.Dispose(); foreBrush.Dispose(); } } } Sory for this late posting ************************** S r e e j i t h N a i r ************************** Re: How to change default color of Tabpage >> Answer Nick Parker10-Aug-04 4:00 Nick Parker 10-Aug-04 4:00  Due to the large number of posts within the C# forum I would suggest that you consider writing up your findings in an article and posting it, otherwise this post will get lost and won't provide much help for others in the future. - Nick Parker My Blog | My Articles Re: How to change default color of Tabpage >> Answer sreejith ss nair10-Aug-04 17:11 sreejith ss nair 10-Aug-04 17:11  hi, I will do that. why i am simply holding is, i need to explore little more on these sort of controls and their default properties. thanks ************************** S r e e j i t h N a i r ************************** Title bar Height Shiva_Hosa10-Aug-04 1:56 Shiva_Hosa 10-Aug-04 1:56  how to change the Height of the Title Bar for a particular application irrespective of what the user sets the height in Display properties and in Xp and Classic Styles?(in SDK, C#) Setting a policy using c# Freddie8310-Aug-04 1:44 Freddie83 10-Aug-04 1:44  Hello, I have a cute little problem here. I want to enable the logging for login events from within my program, but I cannot find anything about that. In windows you can set it from Local Security Settings -> Local Policies -> Audit Policy. Does anyone know how to do this? I'm really Stuck here. Re: Setting a policy using c# Heath Stewart10-Aug-04 6:43 Heath Stewart 10-Aug-04 6:43  Those policies map to reigstry entries. I recommend you search http://msdn.microsoft.com/library[^] or http://support.microsoft.com[^] to find which registry entry that GPO entry maps to. Then changing is easy: use the Microsoft.Win32.Registry and Microsoft.Win32.RegistryKey classes, which are documented in the .NET Framework SDK and simple enough to use. EDIT: You could also open the policy template (don't remember where it is off-hand, but that is in the MSDN and Support sites, too) and see where it is. The policy templates are pretty simple text files that you could even open in Notepad and search for to find the friendly name (i.e., what you see) and then find what registry key it maps to.   Microsoft MVP, Visual C# My Articles Re: Setting a policy using c# Freddie8311-Aug-04 0:51 Freddie83 11-Aug-04 0:51  Damn, I wish it was that easy, but I've tried everything, and I cannot find the key. Anyone got more ideas? Re: Setting a policy using c# Heath Stewart11-Aug-04 2:28 Heath Stewart 11-Aug-04 2:28  Sorry to say, but that works. All the policies do is set registry keys - nothing more. With some settings, a reboot may be required, though in Windows NT the policy update cycle (default is 15 minutes) is usually sufficient.   Microsoft MVP, Visual C# My Articles Re: Setting a policy using c# Freddie8311-Aug-04 2:50 Freddie83 11-Aug-04 2:50  Okay, I found it, the thing was that the registry key was secured, so I couldn't see it myself. Adjusting permissions edited the whole issue. Just one problem, I need to read the Default Value of the key HKEY_LOCAL_MACHINE\SECURITY\Policy\PolAdtEv, but how the hey can I do that, If I want to read a keyValue, I must supply a keyname, but the defaultvalue hasn't got any :S. thanks for your help so far, I wouldn't have gotten this far without it. Re: Setting a policy using c# Freddie8312-Aug-04 5:50 Freddie83 12-Aug-04 5:50  Okey, I found how to read the default value. But now I've got a whole different problem. Since th type of value is REG_NONE I cannot get the value out. even though I know it is Binary. Does anybody know how to read this kind of values anyhow? Or another workaround?

Heath Stewart10-Aug-04 6:41 Heath Stewart 10-Aug-04 6:41  http://msdn.microsoft.com/library/en-us/dnanchor/html/windowsmobile.asp[^] This has nothing to do with C# or the Compact Framework, which is for writing applications - not organizing them. The directions for doing these things are the same for any application written in any language.

Re: Get RichTextBox's content as Image Heath Stewart10-Aug-04 6:38 Heath Stewart 10-Aug-04 6:38  Read How To Print the Content of a RichTextBox Control By Using Visual C# .NET[^] and modify the Print method documented in the KB article so that it accepts a Graphics object as the last parameter instead of a PrintPageEventArgs (you'll need to pass a struct for margins as well). This will allow you to pass a Graphics object (ultimately, the HDC - or handle to a device context - is used) for printing or to save an image.   Microsoft MVP, Visual C# My Articles register C# window ting6689-Aug-04 22:45 ting668 9-Aug-04 22:45  HI~ I am using compact framework and I have written a class which extend Microsoft.WindowsCE.Forms.MessageWindow How do I register the window class in C# so that I can find the window by using the function "FindWindow" ?? Note that the handle of the message window is existed in the instance of the MessageWindow. Re: register C# window Nick Parker10-Aug-04 3:40 Nick Parker 10-Aug-04 3:40  FindWindow is a native function, however if you look at the documentation for FindWindow[^] on MSDN you will see that if you pass null for the lpClassName parameter it will find any window whose title matches the lpWindowName paramter. The P/Invoke signature for FindWindow is as follows: [DllImport("user32.dll")] static extern IntPtr FindWindow(string lpClassName, string lpWindowName); This works if you pass null as the first parameter, however if you want to specify the class name, you will have to override the CreateParams and specify the ClassName property. - Nick Parker My Blog | My Articles Re: register C# window ting66810-Aug-04 15:41 ting668 10-Aug-04 15:41  Yes. However, the message window has no window title So I cannot use the second parameters. I would like to get the handle of a window which has no window title as the window is not a form and also the window is a class of of C#. Also I use compact framework so there is no System.Window.Forms.CreateParams. So... How do I get the handle of the window? Thanks check if minimizebutton was clicked Stephan Wright9-Aug-04 22:16 Stephan Wright 9-Aug-04 22:16  Hy everyone! Could anyone of you tell me how to implement checking if the minimizebutton on my WindowsForm was clicked? I had a solution which worked but well when I switched over to another application to drag&drop some data the application was minimized as well and no longer shown in the taskbar. But what I want to do is: When switched to another application to drag&drop data the application only moves to the background but is still be shown in the taskbar. If the minimizebutton was clicked then my application should minimize and not be shown in the taskbar (except the icon to resize my application once again). Thanks! Stephan. Re: check if minimizebutton was clicked sreejith ss nair9-Aug-04 22:39 sreejith ss nair 9-Aug-04 22:39  hi, Minimizing a form to an icon at run time generates a Resize event. The WindowState property reflects the current state of the window. If you set the WindowState property to 1 (Minimized), the Form is minimized independently of whatever settings are in effect for the MinButton and BorderStyle properties. private void Form1_Resize(object sender, System.EventArgs e) { if(WindowState == FormWindowState.Minimized) >> check this } ************************** S r e e j i t h N a i r **************************
