Thanks in Advance Pavani tab key in a textbox felixdisc5-Feb-09 23:15 felixdisc 5-Feb-09 23:15  Hi, I want to give a value in a textbox when the 'tab' key is pressed in another textbox. My code is this: private void textBox1_KeyPress(object sender, KeyPressEventArgs e) { if ( (e.KeyChar.Equals(('\t'))) || (e.KeyChar.Equals(Keys.Tab)) ){ this.textBox2.Text = "hola"; } } But the only way that it works is to set the 'Multiline' and 'AcceptsTab' properties to be true (both properties at the same time, unless it not works). And the problem is that on this way, to press the tab key the focus not change to another textbox. Anybody knows a better way?

Re: tab key in a textbox felixdisc5-Feb-09 23:30 felixdisc 5-Feb-09 23:30  It is a good alternative. I can use the keyPress event for the intro key, and the Leave event for the tab key. Ok, thanks windows service created in 2005 .net is not running in vista arun_pk5-Feb-09 23:00 arun_pk 5-Feb-09 23:00  2869 is the error code which is shown while installing the service setup .The service is working good in XP. is there any thing which i should add while creating service to run in vista Re: windows service created in 2005 .net is not running in vista musefan6-Feb-09 0:31 musefan 6-Feb-09 0:31  dont know the error code but when i had a vista issue, it was to do with the project manifest, maybe you could look at that. Its to do with trusting the application or something My opinion is...

Its somesort of xml coded file that determines how the application should run, i.e. as administrator or user etc. I cant remember in detail have a look at this or search c# manifest or something http://support.microsoft.com/kb/944276[^] My opinion is...

Not that it matters now but the reason that I asked why was so that I could get a better handle on what the OP was really trying to do, the better to formulate a sensible reply.

I have a website where i sal computer and other stof, every day i get i xls. file from one company with price list model number, description and other thing. Every product in my website has parnumber: thats unik. So i want to make a function in c# to update the price in mysql database because the price changes every day. How can i make a function like update table_name from c:\test.xls (take just price and partnumber from xls file ) where partnumber=(partnumber from xls) ? I hope really much you can help me. Re: My SQL Import xls files Christian Graus5-Feb-09 22:21 Christian Graus 5-Feb-09 22:21  You will need to write code to parse the Excel file ( either export as csv, or use the Office interop stuff ), then write your SQL.

Re: My SQL Import xls files Christian Graus5-Feb-09 22:45 Christian Graus 5-Feb-09 22:45  Not really, no. Connecting to a db is trivial, and widely documented. Parsing a CSV is trivial, use File.ReadAllLines and the Split method on the string class to break each line into discreet items. Controlling Excel is also well documented.

That was some 3 years ago, so I no longer have the code. I did a google search for "C# import excel file into sql" and I found the same link I had used to write the code some 3 years ago. The link: http://davidhayden.com/blog/dave/archive/2006/05/31/2976.aspx[^] I recommend you use this link to do the following: 1) SQLBulkImport the Excel file into an import table (a table in the same database but that is only used for this purpose) 2) Call stored procedure that grabs the needed data from the import table and updates whatever table(s) you need to update. In my case, I had a Unique partNumber, too, so I would A) Mark records in my primary table as "inactive" (I use a tinyint with 1=inactive and 2=active) that were no longer in the import table B) Add new records from the import table into the primary table. C) Update records in the primary table with changed values in the import table (usually the description and price). Hope this helps.

Look into 'Custom Events' and 'custom Event Handlers'. That should get you started. Simulation of Circuits sabeel alwosol5-Feb-09 21:33 sabeel alwosol 5-Feb-09 21:33  hi...
