Re: Flicker Free Listview leppie13-Jun-02 21:06 leppie 13-Jun-02 21:06  I had a similar problem a while back. Make sure that: 1. the control dont get invalidated after adding each item 2. you are not adding new items using AddRange() within a loop. Hope this helps Re: Flicker Free Listview Brandon Parker14-Jun-02 4:05 Brandon Parker 14-Jun-02 4:05  So should i be using the style controls? Free Windows Form Designer Gavin Jerman13-Jun-02 6:19 Gavin Jerman 13-Jun-02 6:19  I can't afford a copy of Visual Studio .NET for home use, so I'm trying to learn C# and .NET the cheap (hard) way i.e. the .NET SDK, a text editor and the command prompt. What I'd like to write are some Windows Forms applications, but I can't stand the thought of having to write the form layout by hand. Does anyone know of a free form designer that I can download and use with C#?

Using context menu item in main menu? Martin Haesemeyer13-Jun-02 4:48 Martin Haesemeyer 13-Jun-02 4:48  Hello! Is it possible to reuse context menu items in the main menu(maybe from the designer,too) ? Or do I have to declare two menu items for duplicate commands and enable/disable them seperately for the same reasons (because something like CloneMenu would only clone the current property values me thinks)? Cheers and TIA Martin "Situation normal - all fu***d up" Illuminatus! C# Controls - 3 questions Maciej Pirog13-Jun-02 4:02 Maciej Pirog 13-Jun-02 4:02  Hi there! I've got 3 questions about programming C# controls: 1. How can I bind my own property to one of the categories that are displayed in the Properties window (like 'Behaviour' ora 'Apperance')? Can I make my own cathegory? 2. I would like the control to know, if it's in a Design mode or in a running app. User has to add all data to my control dynamicly and I want control to display some example while being in Design mode (sth. like TreeView in Win32 API in Resource Editor). How can I implement thing like that? 3. How can I change the control's icon that is displayed in the Toolbox? Please! Help me!

Embed a bitmap in your assembly named the same as your control's fully qualified typename (plus .bmp). So if your control's full name is MyNamespace.MyControl, 'embed as resources' a 16x16 bitmap in your project named 'MyNamespace.MyControl.bmp'. Recompile, and studio should use that bitmap on the toolbox. Check out the code for PropertyTree for an example of embedding Toolbox bitmaps in a control assembly. -- Russell Morris "WOW!

I think that this is a very good approach in order to build Object Orientated Models. Is there some kind of possibility to generate C# code stubs out of the ORMs yet. I think that this is the very missing stone in the whole idea. If we think further the information stored within the ORM would allow generating some kind of a Ralational-Object Mapper code including simple SQL. So if you changed your ER Model or add some new “Facts” you would just generate your ALTER-nation statements for the DB and generate new C# classes including the update of the Relational - Object mapping. Don’t you thing that this is actually the future of how applications will be created?

Ehrnström 12-Jun-02 16:45  I have created a DataGrid and bound it to a DataSet thus populating it with my data. I have also managed to format the columns the way I want them. Now I just wonder if there is any way I could get rid of the first column, the one before my DataSet data. I don't know what it is called, but it is where the selection arrow is displayed, and also the plus sign if I have a relation in my DataSet. Any advice would be much appreciated. I have been looking for a method or property in the DataGrid class to disable this feature, but I have not been successful so far. Re: Customizing DataGrid Rocky Moore12-Jun-02 19:49 Rocky Moore 12-Jun-02 19:49  Have you tried setting the RowHeadersVisible = false ? If you would like to get rid of the row with the '*' on it where it adds new rows, you can use: dataGrid1.DataSource = myDataSet.theTable.DefaultView; ((DataView)dataGrid1.DataSource).AllowNew = false; Where dataGrid = your grid, myDataSet = your dataset, theTable = the table you wish to show. Oh yeah, if you want to get rid of the blank area at the top of the grid that would be the "CaptionVisible" property on the Grid, just set it false. Rocky Moore Re: Customizing DataGrid J. Ehrnström13-Jun-02 4:28 J. Ehrnström 13-Jun-02 4:28  I have tried setting the RowHeadersVisible property to false, but that did not help. I guess that is only used if row headers are defined, just like with column headers, but I'm not certain. I actually don't mind being able to add new rows, so that property is ok. I would just like to get rid of the first, non-data, column in the grid. Maybe it's not possible, or maybe it's more difficult than I believe. Thanks for your effort though, appreciate it! Re: Customizing DataGrid J. Ehrnström13-Jun-02 12:23 J. Ehrnström 13-Jun-02 12:23  I'm sorry, you were perfectly correct about the RowHeadersVisible property. My mistake was that I had tried changing it in the wrong place. Ooops! Re: Customizing DataGrid leppie14-Jun-02 1:22 leppie 14-Jun-02 1:22  Hi I found this to work for me. To get multiple tables on one grid, assign a the DataSource property to a the DataSet you are using. To just just view one table (like I understand you want to), assign the DataSource property to a DataTable. Hope this helps Re: Customizing DataGrid J. Ehrnström14-Jun-02 2:10 J. Ehrnström 14-Jun-02 2:10  Actually my problem was not getting the correct table from the dataset displayed in the grid, but just that I wanted to get rid of the row headers (I didn't know that's what they are called before). Now my grid is just showing the data, like I wanted it to. Thanks for trying to help though! Dimming an image Rama Krishna Vavilala12-Jun-02 16:41 Rama Krishna Vavilala 12-Jun-02 16:41  How do you dim any image so that a text written on top of it becomes very clear. I am not satisfied by controlling the alpha. Can it be done thru' SetColorMatrix any ideas what I need to do? Re: Dimming an image James T. Johnson12-Jun-02 20:04 James T. Johnson 12-Jun-02 20:04  This response skirts your question, but maybe it'll help anyway I just outline the text with a color that would make the text stand out on; you wind up with 4 extra DrawString calls, but those should be faster than dimming the entire bitmap. This is the most common technique used for subbing a film. James Re: Dimming an image Rama Krishna Vavilala13-Jun-02 7:00 Rama Krishna Vavilala 13-Jun-02 7:00  No I don't want that. Lets say I pickup the image of bob from CP website or for that matter your pic and I want it as a background of lets say a webpage. What all do I need to do so that the text is clearer and the image is also not that bad. Re: Dimming an image Chris Losinger13-Jun-02 7:03 Chris Losinger 13-Jun-02 7:03  sounds like what you probably want is to reduce the image's contrast. not sure how you do that in C#/GDI+, tho. -c Cheap Oil.
