In C# whenever you see ()’s used it means that you are calling a method while the use of []’s means that you are passing in an array index or key into an array type object. 2.

• Visual Basic Searching Records on Windows Form

  I can't seem to find a solution for this anywhere! Everywhere I've searched on Google always shows me how to do this with a datagrid - but not a form. I've created a form which correctly displays all my fields in a recordset. I can scroll through them, add new records, delete records, etc. etc. and everything is fine. I now want to add a Search field to the form so that when the user enters a search string, it automatically searches through the dataset and refreshes the display to display the appropriate search result (i.e. populates the currently open form with the appropriate record). Any help will be appreciated. A bit of background: - I am using a sql server database and a windows ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. dxdiag under Direct3D 10?

  Hi all, is there anything like DirectX Diagnostic Tool (dxdiag) for Windows Vista x64 I wanted to do some performace testing on my ATI 19000XTX. I want to check if the low FPS on some D3D 9 games is because of D3D 9 emulation or driver issue. My guess is that the driver works fine, but the software is not optimised to D3D 10 & Win Vista 64bit. Is there any workaround to speed up non "D3D 10 & Win Vista 64bit" software Regards, JoeBlk Thank you for the information Jack. I will try to find the dxdiag tool. I will sit and wait for ATI to improve the drivers and wait for the software developers to improve their products. :) In the meantime i will start reading/learn more about ...Show All

• Visual Basic Moving a form.

  Hi there, Currently in my application I have made it so I have no form border. I have put in my application.exit and minimize code but I'm wondering what the code is to move the form around ONLY when pressing down on a button/control. Thanks, AliQ Hi, I've been playing with this which moves the FORM to 250,250 on button1 being clicked. The second Sub will move the FORM around when you click a mouse button on it, but i'm still working on doing this while a button is down. Me.DragDrop may be the way to go ahead with this, i'm not sure.
