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.

Ive copied the file into a byte[], but now i need to be able to send that as text. any suggestions? i think this is easier than im making it, but ive never done anything like this. Re: Pushing binary through MSNM Rocky Moore12-Jun-02 19:52 Rocky Moore 12-Jun-02 19:52  I prersonally did not get the MSN MessengerAPI to work under C# (of course I could never get the Key from Microsoft for testing. Or are you by chance using the older API? At the moment I am using the direct method to the server. Rocky Moore Re: Pushing binary through MSNM 13-Jun-02 4:29 13-Jun-02 4:29  I've got the code from Sells Brother's site. works perfectly. http://www.sellsbrothers.com/default.aspx what do you mean by direct method? I am going to push a byte[] onto a string buffer using spaces between entries. is that a good method?

The first page of the MessengerAPI by Microsoft states that you need an ID/Key pair to use the API for it to connect to the server. You need this to connect first to the test servers and once your code is provide a new ID/Key set for the production servers.
