Dave Kreskowiak Microsoft MVP - Visual Basic Key Board Essentials Syed Shahid Hussain11-Oct-06 7:07 Syed Shahid Hussain 11-Oct-06 7:07  Hi, I want to khnow the Key codes of both "Enter" buttens one is at alphabetside and other is numpad side. Also I didn't find the key code/name of properties key and all num pad keys i.e /,*,-,+,.,enter is remaining. Please tell me Key.NAMES or Key codes of that. Thanks Syed Shahid Hussain Re: Key Board Essentials Dave Kreskowiak11-Oct-06 8:59 Dave Kreskowiak 11-Oct-06 8:59  Both [ENTER] keys are specified by Keys.Enter. There is no difference between the two keys. They both have the same virtual key code comming out the of the keyboard driver - VK_RETURN. Dave Kreskowiak Microsoft MVP - Visual Basic Re: Key Board Essentials Syed Shahid Hussain12-Oct-06 6:23 Syed Shahid Hussain 12-Oct-06 6:23  Simply my problem is that which [Enter] key is pressed. Can u direct me .... Syed Shahid Hussain Re: Key Board Essentials Dave Kreskowiak12-Oct-06 6:29 Dave Kreskowiak 12-Oct-06 6:29  You can't get this information unless you write a global keyboard hook. There are many examples of this all over the web. A little Google goes a long way. Search for "c# keyboard hook[^]" and you'll come up with examples. THe very first link is an article right here on CP.

Syed Shahid Hussain Memory Management in Multi Form Application Syed Shahid Hussain11-Oct-06 5:44 Syed Shahid Hussain 11-Oct-06 5:44  Hi, I have developed a multi form application with graphice and sounds effect but when I run the application it holds a lot of memory. Can any one give me the idea for fast running of my application. Thanks Syed Shahid Hussain Re: Memory Management in Multi Form Application Dave Kreskowiak11-Oct-06 5:59 Dave Kreskowiak 11-Oct-06 5:59  You're going to have to be more specific than that. There's hundreds and hundreds of techniques, but what you do depends on how you've written your code and what your code is supposed to be doing. There's just no way to answer this question with the information you've given. If your app is just consuming memory until the system runs out, then you've got a problem where your not releasing resources properly, like calling Dispose() on objects when you're done with them.

I think it has something to do with using Server.MapPath to generat the path to the report you want, but I don't know for sure.

Give me sample code for connection. Thanks........ Re: DB2 in .Net Dave Kreskowiak11-Oct-06 6:12 Dave Kreskowiak 11-Oct-06 6:12  You'd be using the System.Data.OleDb if you're not using one supplied by IBM.

Re: DataGrid/Combobox Dave Kreskowiak11-Oct-06 6:09 Dave Kreskowiak 11-Oct-06 6:09  You're question is a bit vague. What do you want this combobox to do? Is this box going to be bound to a datasource so you can pick values from a table? Are you supplying your own values, seperate from a database? Dave Kreskowiak Microsoft MVP - Visual Basic Database help eric_tran11-Oct-06 2:42 eric_tran 11-Oct-06 2:42  Good day everyone, I'm doing a project with database MS Access in VB.Net 2005.

My first guess would be timezone problems, but since we don't know anything about your code or the databases involved, there's really nothing we can tell you. Dave Kreskowiak Microsoft MVP - Visual Basic how can I stop displaying error messages on webBrowser Ali 11011-Oct-06 0:16 Ali 110 11-Oct-06 0:16  Hi Members, I am working on a Desktop/Windows Application. Can anybody help me that how can I stop displaying error messages on webBrowser control when an error occured in displaying page. Thanks in advance Regards Re: how can I stop displaying error messages on webBrowser Dave Kreskowiak11-Oct-06 2:00 Dave Kreskowiak 11-Oct-06 2:00  You can't stop them from popping up. At least not without modifying the options for Internet Explorer. The WebBrowser control is actualy an IE component that uses all the same settings as it's Blue E counterpart. Changing system settings is NOT recommended to get the functionality you want. Dave Kreskowiak Microsoft MVP - Visual Basic get clicked link m_mor10-Oct-06 23:15 m_mor 10-Oct-06 23:15  hi .
