• Visual Studio Team System Custom Rules Development

  Okay, okay so I know that any rules I write now will need to be re-written with the next release of Visual Studio, however I write (and maintain my own rules and now I'm stuck) .... I've been tasked to write a rule that checks for multiple return statements in methods, this is to help enforce the structured programming principle of methods having single entry/exit points that some of the junior developers consistently ignore. The problem I have is that with introspection I only get the MSIL, which is of course optimised. The optimisation process [is so good that it] actually restructures the code, eliminating all return opCodes exc ...Show All

• SQL Server SQL Server Mobile with Visual Studio 2003

  I've recently noticed the availability of SQL Server Mobile, and would like to take advantage of some of the new features, however, I'm currently using Visual Studio 2003. The requirements state that Visual Studio 2005 is required, but I was wondering if anyone has had any success getting it to work with VS 2003 I hope that I can do this with VS 2003, but if VS 2005 will be required, I'd like to clear up a few issues before asking my workplace to fork out more money for the upgrade: What have your experiences been like in getting clients to upgrade from SQL Server CE to SQL Server Mobile I've seen some postings regarding p ...Show All

• Visual Studio Express Editions Treeview Nodes

  Hello, I have a treeview control with a parent and 2 child nodes. When I run the application the parent node is closed. Is it possible to run the application with child nodes showing I thought there may be a property for fully expanded but can't seem to find one. Thanks Unfortunately there isn't a property that allows you to set this (IsExpanded is read-only). You instead have to call a method on the node you want expanded (in your Form.Load for example): Do the following to expand the first node of the TreeView: this .TreeView.Nodes[0].Expand();   Do the following to expand the first node and it ...Show All

• Windows Forms Custom controls Docs

  Hi, Where can I find docs about creating custom controls I mean, I need the reference that says how to interact with the object inspector and the form layout. Create that arrow on the right top corner of the control, and others... This is the basic and everything is derived from this. If you need something more advanced, just ask. about the icon, the best way is to create a 16X16 bitmap and give it the full namespace name: MyNameSpace.UserControl1.BMP. add it to the project, set its properties BuildAction to Embedded resource. on the user control header: [ ToolboxItem ( true ), ToolboxBitmap (MyNameSpace.User ...Show All

• Software Development for Windows Vista BPEL conversion

  Hi, I'm currently working on a project investigating the possibility of WF in combination with other products (mainly microsoft). An important question in this project is the relationship with BPEL and importation from other workflow (design) tools. BPEL being a good “general” format to use for import/export. In some articals I have read that Microsoft is working on a BPEL import/export tool for WF, when will this tool see daylight and when will we be able to use it. If it doesn’t come out in short time, it will mean we have to develop something for ourselves to do the import from BPEL to WF. This does make the projec ...Show All

• Visual C++ extracting function prototypes (header info) form a DLL

  Hi, we're trying use the functions in a DLL in Matlab. Matlab requires the DLL (which we have) and a file containing the function headers (declarations, prototypes, whatever you call them). My question is since we have the DLL is it possible to extract the function headers Can this be done in Visual Studio, if so how or is ome other software required Thanks, Cliff Having only a DLL with (maybe) plain names (without name mangling), you have no chance to generate the function headers without debugging it. ...Show All

• Visual Basic when true isnt really true

  A feature I think would be the best way to describe this... or at least it doesnt behave how I would expect... Try the following: debug.print(true) I would expect a boolean value of -1 to be returned.... true being defined in the VB docs as being a boolean value of -1 with false being a boolean value of 0. What I actually get is a string value of "True" Ah well.... How did I discover this Well I was pre-populating a checkbox column value with [checkboxcolumnnameyadayadayada].value = True on a datagridview and I was then capturing the on change event, I was getting: Conversion from string "True" to type 'L ...Show All
