• Visual Basic prevent tabpage from changing while input is validated

  Greetings: I've got a tabControl with several pages, and the first page presents a summary of the stuff on the other pages. It is set up so that the user input on the back pages is validated on the textbox leave event. A problem occurs when the user goes from entering some invalid text in one of the back page text boxes directly to selecting another tabpage. The validation error messages get shown along with the summary page error messages, and it is not a pretty sight. I tried using a boolean flag in the tabcontrol.selectionChanged event to try to stop the selection change, but that doesn't work. I'm guessing that the selection change event gets fired before the textbox leave event. I've also tried using boolean flags to stop the ...Show All

• SQL Server Cubes and dimensions disappear random

  Hi, Since today cubes and dimensions disappear random at our customers site. Without any pointable reason the cubes and dimensions will be deleted from the cubes and dimensions folder within the analysis services database. We have double checked no one removes the cubes or dimensions. After restoring the backup file the database will run for several minutes/hours and then for some reason the cubes and dimensions disappear. We are running sql 2005 standard with SP 1. Anyone knows how we can trace the events or track what happened We have restored the as database multiple times (untill now 5 times) and the problem still keeps returning. No settings have changed and we are running the AS database for about one week from now. I have checked ...Show All

• Visual Studio Team System Unable to cast to type 'Microsfot.VisualStudio....'

Do you get a exception dialig where you can choose Debug If so it would be a big help if you can get us the callstack dump in the exception. If that is not the case; it helps to know if you can repro this at will If so can you give us ...Show All

• Visual Studio 2008 (Pre-release) Overlapping elements over a FlowDocument

  Hi, I have a FlowDocument with sections, paragraphs, lines, etc. My target is (for example) to draw two lines in order to create a cross over the page (from angle to angle) so that the lines overlaps the entire page content. Another example is to overlap a big text like "Confidential" over (or behind) the content page. I tired using floaters but they need to be inside an inline, so they take space and modify the flow of the page. I want to overlap those elements without changing the normal flow instead. Thanks, Raffaele Thanks Lester for your answer. This solution could be a workaround when I need to put an image below the paragraphs. The problem that remains are: - putting something in front of the paragraph ...Show All

• Visual Studio page count in ReportViewer-Bar -> 1 number too little

  hello there. i render my reports in local mode in a WinApp. when the report got rendered in the reportviewer the report has three pages. in the status bar of the reportviewer i only see "1 of 2" pages. after scrolling or pressing the "next-page-button" the pagecount corrects to three. i suppose that the reportviewer adds repeated (repeat on each page) objects only one time, not three times like in this sample. is this possible is there an update for that Did they fix this in ReportViewer 2008 I have the same problem, but I see the same in 2008 too. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Render to Texture and Shaders

  Hi! I created a volume fog shader, i have 2 passes where i need to render depth of object to textures. How i can pass render targets from DX to shader simple: effect.BeginPass(1); effect.SetValue("back_Tex", backTex); effect.SetValue("ViewProjection", device.Transform.World * device.Transform.View * device.Transform.Projection); mainMesh.DrawSubset(0); effect.EndPass(); dont work :( Ok, you have to do some steps: 1) Ensure that you texture are render targets: LPDIRECT3DTEXTURE9 myRenderTexture; D3DXCreateTexture(m_pd3dDevice, xres, yres, 1, D3DUSAGE_RENDERTARGET, D3DFMT_X8R8G8B8, D3DPOOL_DEFAULT, &myRenderTexture); Verify that your video card can use the format X8R8 ...Show All

• Visual C++ C++/CLI finalizer chaining in a class hierarchy

  Is the finalizer ( ! ) in a C++/CLI derived ref class automatically chained to call the finalizer of its base class or do I have to manually implement this in my derived ref class The documentation in the "Destructors and Finalizers in Visual C++" topic is confusing about this. Also if the finalizer is protected rather than public will it still be called originally by the GC ref class Base { public: !Base() { /* Release unmanaged resources */ } }; ref class Derived : public Base { public: !Derived() { /* Release unmanaged resources */ // Does !Base(); have to be manually called } }; Peter Ritchie wrote: From Destructors and Finalizers in C++ : Unlike Visual C++ ...Show All

• Windows Search Technologies Improving the users' experience of window desktop search

  I am into design of interface to improve "users' experience" in using a software. I was studying the 2 Desktop search from both side, Microsoft & Google. While the great engineers of both company create a great product, I see that both are now offering a common function. As we know, Desktop search primary objective is to capture users for the search engine and the functionality of easy-search in our desktop is just additional functionality to ensure web search is readily available in our computer. What else the great engineers from Microsoft can add to Windows desktop to ensure it is selected over the other competing desktop search My suggestion is to add dictionary that will be available even the users are offline.

• SQL Server Could not Authenticate with SQL Server

  Here's my situation and I've spent enough time to troubleshoot. Any help would be appreciated. 1) I have a VB.NET Windows Form Application that uses SQL Server Express 2005 database. 2) The "mdf" file is a part of the application itself. 3) When the application distributed to my clients using Windows XP SP2, the "Click Once" installer automatically installs SQL Server 2005 Express [which is a pre-requisite] and copies this mdf file into the application folder. 4) The authentication mode is "Windows Integrated" The problem is, when the application is launched [while logged in as the local system administrator in a given computer], it is unable to connect to the SQL Server.

• Visual Studio Team System How do I add a new report to the Project Portal?

  Hello, I've just created a new report and would like to add it to the team project portal. I'd like it to show up just as the "Remaining work" report does. How can I do this Cheers, Chris Most of the time we recommend reports be kept on the reports server (in the Reports node). Out of curiosity, why would you want to store the report in sharepoint instead of the reports server You could try and publish the reports to sharepoint (like any other file), but I'm not sure how useful that would be. ...Show All
