Re: Text box scrolling Andy Brummer9-Apr-04 11:08 Andy Brummer 9-Apr-04 11:08  WM_VSCROLL works great, I used the technique from this article Controlling scrolling with the API. I was able to get the two boxes to scroll from a scroll bar just fine. The problem is getting the notification messages from the textBox back to the main window. It seems like .net doesn't expose the dialog notification messages to any of the form code.

What i want to do is when i double click an item on the list i want that song to play (not select it then press play). Think of media player 9, with the playlist on the side, double click a song and it plays. Also i want to color of the text that i double clicked to change. Does anyone know a way to do this or can point me out to an article? Im using WMP9 sdk to play the song so the list box will be reference to the WMP Playlist object, I dont know if i can just add the wmp 9 playlist to my program without using a list box (if there is a way that would help). modified 16-May-21 21:01pm. Re: double clicking an item in a listBox Heath Stewart9-Apr-04 7:58 Heath Stewart 9-Apr-04 7:58  So handle the DoubleClick event on the ListBox, inheritted by Control. FYI, in Windows Media Player, that's a ListView, not a ListBox. There's a big difference and a ListView implicitly supports the kind of object selection and activation changes you want. For example, simply set ListView.Activation to ItemActivation.TwoClick and you've got what you requested. You can either handle the DoubleClick event as before, or the ItemActivate event that is fired when the user activates an item based on the Activation property setting.   Microsoft MVP, Visual C# My Articles Re: double clicking an item in a listBox User 9625789-Apr-04 8:50 User 962578 9-Apr-04 8:50  Thanks ill try ListView instead. Does it support color change of a selected (double click) item? modified 16-May-21 21:01pm. Re: double clicking an item in a listBox Heath Stewart9-Apr-04 8:58 Heath Stewart 9-Apr-04 8:58  It encapsulates the same List-View common control that's ubiquitous in Windows Explorer. So yes, of course it supports changing the color of the selected item, along with much, much more. Read the class documentation for the ListView control and give it a try.   Microsoft MVP, Visual C# My Articles Re: double clicking an item in a listBox User 9625789-Apr-04 8:44 User 962578 9-Apr-04 8:44  ok i got the double clicking an item thing down.

Drawing RichText on a GDI+ surface Judah Gabriel Himango9-Apr-04 7:27 Judah Gabriel Himango 9-Apr-04 7:27  I have a custom control that displays thousands of items. Each item is NOT a System.Windows.Control; each item is instead a simple light weight class with properties (such as .Text, .ImageIndex, etc.) used by the custom control to draw each item (i.e. the custom control draws all the items). Here's my problem: I would like each item to display RichText. While we could write a custom RTF parser, that is a huge undertaking we'd not like to start. We cannot use the RichTextBox provided with the FCL since it is a standard System.Windows.Control which is not at all lightweight (thousands of items == thousands of RichTextBoxes, translates to bad performance plus lots of limitations related to standard WinForm Controls). So I guess I'm looking for a way to display Rich Text items, thousands of items, all on a single GDI+ surface, without utilizing thousands of RichTextBox controls. Any suggestions? --------------------------- He who knows that enough is enough will always have enough. -Lao Tsu Re: Drawing RichText on a GDI+ surface Heath Stewart9-Apr-04 7:53 Heath Stewart 9-Apr-04 7:53  See HOW TO: Print the Content of a RichTextBox Control By Using Visual C# .NET[^].

I've got a couple of questions though, hopefully you've got my answers for me Heath. Since I want to be outputting the rich text to a GDI surface rather than a printer, my thought is that I should use SendMessage and pass a WM_PAINT message. Is that what I should be doing? If so, I fail to see how I can pass the rich text to be drawn on that control. Or should I not be using WM_PAINT at all? --------------------------- He who knows that enough is enough will always have enough. -Lao Tsu Re: Drawing RichText on a GDI+ surface Heath Stewart9-Apr-04 10:04 Heath Stewart 9-Apr-04 10:04  Forget about all the painting-related stuff in the article (the code at the bottom of the article). The important thing is giving the FORMATRANGE.hdc field a valid HDC and passing that struct to the RichTextBox*. It will paint the RTF in that range to the HDC. This device context handle could come from the container control that contains all your little drawing helpers, or they could create their own (though that'd be a little less efficient, but it depends on your circumstances. * You could use a single RichTextBox to help you paint all your RTF. So long as it's not visible nor added to a container control's Controls property collection, it should be pretty efficient and certainly takes care of the task of parsing and painting the RTF to a device context. Keep in mind, however, that the RichTextBox merely encapsulates the Rich Edit common control. If you wanted, you could encapsulate that with your own little bare-bones control, just enough to wrap and create the proper window class, or - even better - use Windowless Rich Edit Controls[^].   Microsoft MVP, Visual C# My Articles FtpServer Member 7326719-Apr-04 6:26 Member 732671 9-Apr-04 6:26  How can i send files from Ftp Server to clients?... also...i want afree source for a ftp server in C# Language Re: FtpServer Nick Parker9-Apr-04 6:43 Nick Parker 9-Apr-04 6:43  Did you look at the articles under the C# tab here at CP?

The Report works fine on my computer but gives a error "Cannot find keycodeV2.dill, or invalid keycode" when I try to display the report on another computer. I have been on a lot of message boards and have found that a lot of people have been having this problem. I know that I need to have the Crystal Reports merge modules included with my project. I am new to .Net and I am not sure that the I included the merge modules in my project correctly. This is what I did. 1. Right clicked the deployment project in the solution explorer. 2. Moved to "Add" on the menu. 3. Clicked "Merge Module" on the menu. 4. Found the merge modules in the Add Modules dialog box. Is this all I need to do to include these merge modules in my project? Am I leaving something out? Is the problem elsewhere? Re: Crystal Reports Merge Modules Heath Stewart9-Apr-04 7:08 Heath Stewart 9-Apr-04 7:08  See Deploying Windows Applications with Crystal Reports[^] in the VS.NET documentation. Besides the 3 MSMs required for the Windows Forms client, you also need to change a custom property for the Crystal_regwiz2003.msm that includes the registration code emailed to you when you (should have) completed the registration wizard when you began using Crystal Reports for VS.NET.   Microsoft MVP, Visual C# My Articles
