• Visual C++ invoking cl.exe using CreateProcess

  I have a program which uses the cpp to parse input files. It invokes cl.exe using CreateProcess. However, I get the errormsg about mspdb80.dll. I have run vvcvarsall.bat, and from the command line it works normally. I can sove the problem by copying all the necessary files of the C compiler into a different folder and adding that to the path. Is there perhaps a more elegant solution I think that simple solution is to run this program with environment variables set to VS variables. For example, you can create batch file which calls vcvarsall.bat and then your program. ...Show All

• Visual C# MapPoint - Faster Route Calculation (Performance Problem)

  Hi, We currently are evaluating MapPoint to use in conjunction with our software. Among the needs is a fast path calculator. The main use is to get the travel time and mileage between 2 stops. Any other information (including directions) is non-necessary and a loss in processing. Our first performances tests seem to show that the path calculator is 4 times slower than competing products. The 2 options I am looking for is A- Is it possible to ask for a cost matrix (i.e. send many stops and get the cost/duration between each stop combination) or B- Are there ways of asking for these 2 informations that would make it run faster Note, I'm not looking for solutions of embedding it as an add-in, more about what can I do different wit ...Show All

• Visual Studio 2008 (Pre-release) Is this a defect?

  Hello, I have a very simple listview in my window. The listview's view property is set to a gridview. When the listview is contained in a stackpanel (Orientation=Horizontal) my listview loses its scrollbar and some of the columns disappear under the window's right edge. When I change the Orientation=Vertical, then everything is fine again. I'm new to WPF so I can't tell if this is a defect or it is supposed to behave this way Thanks Houman <StackPanel Orientation="Vertical"> <ListView x:Name="InboxListView" DataContext="{Binding ElementName=win, Path=Pictures}" ItemsSource="{Binding}" Margin ="5,5,5,5" View="{StaticResource DetailView}"/> </Stac ...Show All

• SQL Server run sql query on multiple databases

  I need to run a same query on 15 different databases and union the results. Does any of the experts know how to do this with good performance Any help is appreciated. Phil....the only reason i posted in T-Sql is because i will be using this query in reporting services :) Thanks Nice to see you over here... The only reason I invited you over here is that using the power of SSIS may be better suited than doing a large cross-database query. Here's what I'd suggest... Build a package in SSIS that connects to all of your various databases, and then using the union all component, you can store the results in a staging table to be used in SSRS. Or do you need the results real-time ...Show All

• Software Development for Windows Vista Radio Button Patterns in WPF?

  I am trying to write an automation provider for a collection of radio buttons in a WPF application. The help files seem to indicate that I should implement a selection provider pattern for the collection, which would mean that the Radio Buttons support the Selection Item provider pattern. Unfortunately radio buttons do not seem to support any Automation patterns. Does this mean I will need to create a custom Radio Button class that implements the pattern I need to use or is there an easier way around this problem HI, I am using the below code to select the radioButton but i am getting the error( given below in red). It seems that radio button don't support selectionItemPattern. I am using m ...Show All

• Visual C# How to build a global connection with ODBC?

  I could not create a global connection with ODBC. It needs to identify in a method, not in a class out of a method. In this case while program running, it builds and destroys million connection.
