• Windows Live Developer Forums How to call a web server asyncronously without ActiveX

  My article at http://www.codeproject.com/jscript/MSNMessengerActivity.asp shows how to call a web server from your MSN Messenger Activity without using ActiveX. When the update gets added by tomarrow hopefully then it will also show how I simulated a mouse pointer so that each user can see the others mouse movements without using ActiveX.   Check them out if you need either of these techniques for your activities.

• Visual Studio What is orthodox way of creating a 1:m report

  All of the quesiton below has to do with producing a report in local mode in VB.net. It is not clear to me what the report designer considers orthodox with regard to creating a One to Many report.  Let's consider a simple invoice report.  At the top of the Invoice you would have information on the Customer you are sending the invoice to ect, but on the bottom part of the report you would have the line item entries for the report in a table. When creating such a report, how does the report writer most like you to do it   I can think of two or three ways.  One, if you are creating a report for just one invoice number, ...Show All

• Windows Live Developer Forums Debug and plugin reload with MSN Messenger API

  Hello, I'm creating a MSN plugin using MSN Messenger API and MsgPlus API in C# and there are two things that frustrating me: debug and plugin reload. Is there a way to reload a plugin in C# Although I can reload it making a call to msgplus like this: int msg = RegisterWindowMessage("MessengerPlus_PluginChange"); int retVal = SendMessage(0xffff, msg, 0, 0); but i can never change the plugin.dll file since it's always in use by msnmsgr.exe. (vb.net also has the seems to have the same problem, at least that's what I read in msgplus foruns, everything else isn't locked this way and files can be replaced easily.) What's the best way for debugging ...Show All

  Hi, I need my form not to repaint under direct draw... Have you some advice thx Why don't you want it to repaint itself If you're doing the painting yourself, you can do that in your paint message and you can use SetStyles to make all painting occur in the paint message, that should place all painting under your control.

• Windows Forms Winforms Inheritance and MenuStrip

  Hi There,  I hope you are well. I'm building a form hierarchy using VS2005 Beta 2.    My base form has the minimum MenuStrip items required for all forms.  I have changed each menu item to a "protected" access modifier to allow inherited forms to further extend these controls.  Upon inheriting this base form for the first time, I quickly realized the menu strip is non-editable in inherited forms at design time, regardless of the parent modifier. Am i missing some fundamental here   How can the child form have design time inheritance to the menu strip Thanking you in advance for your advice. Kind reg ...Show All

• Visual FoxPro External Connect

  Hi I know in Access you can run SELECT queries on external database. You just have to specify type and path. For example: SELECT * FROM <tablename> IN '' [ type ; DATABASE=<path>;] For dBase data source there are values: dBase III, dBase IV;  for Excel - Excel 5.0, Excel 8.0. What should I write to specify FoxPro type ODBC (but as far as I know existing ODBC drivers do not support VFP9 databases, you can use with older versions or check latest driver specification). If you can work with OLEDB in access then use it. ...Show All
