• CScs Windows does not recongize that i just insatlled a new program.

  I'm writing up a setup application, and when I install the exe file, Windows does not reconginze that I just installed a new program. Do I need to create a registry file If I do, does anyone know how to create one and what do I need to put in there in order for Windows to reconginze that a new program has been installed.

• UmerTahir Extending DataGridViewTextBoxColumn to DataGridViewHtmlColumn

  I'm tring to create a better way to present data in data columns. I've decided to extend the d.g.v.TextBoxColumn, although perhaps I should be using a higher level base class. The fist thing I've decided to support are newlines or [br] ( breaks ). this done, Im not sure the best way to calculate row height, or how to effectively set it. I've tried inside the overridden Paint method to set [ this.DataGridView.Rows[ index ].Height ], but it doesnt seem to be affecting anything perhaps I have to change a related flag so the problem, is that I now have a multiline text column that is cutting off the text because the row height is not appropriatly set. any help is greatly appreciated! -stellar ...Show All

The problem is the text file generated by excel script contains some special characters such as " c" , " R ". These special characters are ignored by the vb.net.

Then streamreader can read all text. Thanks Ying Hi, It probably has to do with the encoding of the file. Here's a link to more informat ...Show All
