• Windows Forms DataGridView Combobox databindings - for the experts

  A normal combobox has databindings so that data for DisplayMember, ValueMember and SelectedValue can be taken from several tables. Does this ability exist for DGV comboboxes I don't see any DataBinding collections. Ok, thanks, Ken. Now I know it wasn't just my inexperience with the class. Fo rme to construct a more useful DGV would be asking a great deal. Would the additons be included in the V2005 Express SP1 Beta In fact it would be helpful if someone knowledgeable posted a message explaining just what types of objects would be addressed in the SP1 Beta.. Certainly not .NET framework software, but what else ...Show All

• SQL Server Getting proc name from within .Net code

  Hi, I'm currently in the midst of writing my first sqlclr sproc. In our normal T-SQL sprocs we use the following: OBJECT_NAME ( @@PROCID ) to get the name of the sproc. We later use the result of this as a parameter to a custom message when we use RAISERROR . Question is, is there a way of doing the same from within a SQLCLR sproc i.e. Can someone give me a bit of code that will return the name of the current sproc (Obviously this is not the same as the name of the .Net class that implements my sproc). Thanks in advance for any help that you can provide. Regards ...Show All

• SQL Server Need to join two tables using only part of a field from one of the tables.

  I need to join two tables that both have a field called caseid. The field in table 1 is ten numbers and the field in table 2 is 15 numbers. The 10 most significant numbers are consistant in both table 1 and 2. How do I tell the join to only use the 10 most significant numbers from table 2 Or how do I tell the join to ignore the 5 least significant numbers from table 2 Thanks. Maciej, Thanks for the reply. I wasnt sure if using "Most / least significant" was really appropriate in this case. An example of what I need to do. Table A; field - Caseid contains a value of 3216482469 (This number is specific to one case) Table B; field -Caseid contains a value of 3216482469-1234 The values in Caseid will var ...Show All

  I downloaded everything, SP2, VC++ 5 and XNA, but I cant install XNA. It says that I need to download and install VC 2005, but I did that, I can run VC and do everything with it, but cant install XNA. Whats going on I'm not sure how many times we have to say it, but installing XNA Game Studio Express on Vista is not supported. Your screenshot is clearly sporting the new Vista look, so this is almost definitely your problem.

• Visual Studio Express Editions Reading a web page...

  I have been trying to read from a Web page inside of a WebBrowser control. I can read the entire page code, but can not specify certain areas of the page to read, like a text box. I would like to be able to read just the text box in my web page and have it write the context of the web page text box over to my application textBox... This is the closest I've been, but I can not get it to work at all. It will do the "if ()" event, which is just a message box, but it will not copy the web pages text box contents to my application textBox. <input name="txtName" type="text" id="txtName"> in order to get that element, I would do this: HtmlElement theTextBox = this.theWebBrowserCont ...Show All

• Visual C# Index was out of range?

  I really hate to bother anyone with this seemingly simple question but it appears I am at the dead end. I got this message this morning: Index was out of range. Must be .... Parameter name: startIndex . There are three problem with it. Number one: I have almost debugged this massive application and it seems everything has been working for some time. Unless somehow the input stream's format changed which remains to be checked I do not know where to look. Second, there is no pointer as to where in the source code it happens. And thirdly, I checked and rechecked and I swear I do not have any variable of parameter named startIndex in the entire project. On top of that this error message does not seem to impede the performance. F ...Show All

• Visual Studio Snippet with a generated GUID?

  I picked up this practice of putting GUID's in my exception messages a long time ago. It's slick, if you want to find an exception you just copy the first few chars of the guid and do a search. I have a macro that makes these exceptions now but it would be slick if I could build a snippet that would do the same 'cause then I could do a "Surround with...". Problem is I can't find any articles on making snippets do more than spit out pre-defined code. Can someone point me to an article on inserting run-time data into a snippet Without macros I'm not sure you read my question carefully. AFAIK, snippets essentially take little bits of text and replace them with the values that you type. In the ...Show All
