• Visual Studio How to wrap a DSL diagram inside a Windows Form

  I want to embed my DSL Diagram inside some standard Windows buttons and menus etc - though with all of that still inside a VS window. This turns out to be pretty easy. Here's how: Make a User Control inside your DslPackage project. (In Solution Explorer, right click on DslPackage > Add > User Control.) If you want to put it inside a Custom folder inside the DslPackage project, make sure the namespace doesn't get ".Custom" at the end of it. I cheated and created the file in the main package then moved it into the folder. If you create it directly in the Custom folder, you have to open both of the generated code files to fix the namespaces. Using the usual WinForms editor, add your buttons and menus and ...Show All

• Visual Studio Express Editions Loop

  How do i loop, so that it does not return only 1 email address, and display it in EmailTxt (eg. email@email.com , email2@email.com ") For Each row As GridViewRow In GridView.Rows Dim cb As CheckBox = DirectCast (row.FindControl( "EmailChk" ), CheckBox) 'We are interested in if CheckBox is checked If cb.Checked Then Dim email As String = row.Cells(7).Text EmailTxt.Text = email + "," End If Next End Sub the code: "EmailTxt.Text= " is incorrect. you are pretty much over writing what you already have in that textbox. it should be: EmailTxt.Text = EmailTxt.Text & email & "," ...Show All

• Visual Studio 2008 (Pre-release) Partially Trusted callers

  I'm developing a WCF service that will be accessed from Outlook using the VSTO Second Edition. When I'm calling the generated proxy, the following exception is thrown. "The assembly does not allow partially trusted callers" I read in the documentation that the ServiceModel does not allow partially trusted callers. But how can I make the call if Outlook is not fully trusted Is there a workaround Thanks in advance Janni Kajbrink Hi Janni Yes, you cannot call into System.ServiceModel from partial trust (PT) as it doesn;t have the AllowPartiallyTrustedCallers (APTC) attribute on it. You will have to create a shim that you put in the GAC that has APTC and that asserts full trust (FT) and forwards your call on to Sys ...Show All

• Software Development for Windows Vista error LNK2001: unresolved external symbol "class CFactoryTemplate * g_Templates"

  Hi out there Directshow forum! I'm new on this forum as you can see! I'm developing a directshow pull filter that inherits from CBaseFilter that has the ability of reading a lot of formats from many data sources. I've declared an atl-based interface that defines the generic reading/writing functions and a few clases that implement that interface for exposing the ability of reading from many data sources. That was compiled so good in release and debug mode. My filter has a load function that allows the user to pass that "data source interface" to the filter, to allow the filter to read from the remote data sources. i've declared all the filter dll's stuff, the factory templates and it compiles so fine in release and debug mode! I' ...Show All

• SQL Server Parameterized MDX Query Performance Issue in SSRS

  Hi, I'm having issues with a reasonably complex MDX query used in a Reporting Services report. I have executed the query and traced activity on the SSAS box and have discovered that there is a major difference in performance between the parameterized query and the exact same one but with 'hard coded' values. The difference we are talking about is from a couple of seconds (hard coded) to minutes when parameterized!! The key difference is that the parameterized query is causing litterally hundreds of thousands of Query Dimension events (EventSubClass : 1 - Cache Data) to occur against one of the dimensions (the Date dimension to be exact). This dimension is not even large with only a few hundred leaf level members and about five levels ...Show All

• SQL Server Role design issue

  I have a strange roles problem. Is there a way we can accomplish this: Say, the fact table has 100 records. each record having a new account number (100 accounts in 100 records). The problem is we have users who have to see only some accounts. For example, user 1 has to see only accounts 1-10, user 2 has to see only accounts 11-20, user 3 has to see only accounts 21-30. and so on... I know we can create different roles and create perspectives for these roles, but the problem is the list that defines what they can see is a table of 1000 user entries, each row has its own conditions for each user type. (Actually, each condition is a combination of different dimensions. For example, user 1 has to see account 1-10 and products A-D) ...Show All

• Windows Forms Treeview node cropping

  Does anyone know how to prevent a Windows.Forms.Treeview node's text being cropped if the node's font size is increased or changed to bold The text seems to be cut off roughly where the text would have displayed to if it were in the treeview's font - the final letter is often chopped off part-way through, even though there is plenty of space following. The only work-around I have found is to set the Treeview's font to bold (or larger) and then set the font of all the other nodes (the ones I don't want emphasized) to the regular/smaller font. The problem with this is that the nodes' tooltips display in the treeview's font (ie bold/larger). Reassigning text property won't fix the cropping problem I did the text reassigning when cre ...Show All

• SQL Server OLAP VS Reporting DB.

• Visual Studio Express Editions Can't set breakpoints.

  I opened VBE and loaded a program I had been working on. I set a breakpoint and ran the program. It never stopped at the breakpoint. The breakpoint changed to an unfilled circle with a warning logo. Placing the mouse over the breakpoint symbol I get a pop-up with the following information: The breakpoint will not currently be hit. The source code is different from the original version. To allow the breakpoint to be hit when the source code is different, right-click on the breakpoint choose "'Location...", and turn on 'Allow the source code to be different from the original version.' To allow this for all breakpoints, disable the option 'Require source files to exactly match the original version' under Tools, Options ...Show All
