• Windows Forms Dynamic Filling of TextBox AutoComplete not working

  Hi guys,   i would like to fill the textbox autocomplete stringcollection "on the fly" while typing. i don't want to fill the collection while initializing, 'cause it's too much data: the sql server-table has about 100.000+ rows. the filling takes too much time and the "autocomplete-popup-find-something-box" itself is getting too slow, too. my configuration: .NET-Framework: 2.0.50727, System.Windows.Forms.TextBox TextBox-Properties: AutoCompleteSource: CustomSource; AutoCompleteMode: Suggest i tried several different things... 1. i did put this code in the “TextChanged”-event, but i think it's 'too late' there: private void textTiteUltTest_TextChanged( object sender, EventArgs e) {     ...Show All

• SQL Server ReportItemCollection

  I've asked this question in a few different forums and so far I've had not response, I hope I have some better luck here. I'm writing a custom rendering control to render very basic reports in WML. I'm stumbling at the first hurdle, though. I've added references to "Microsoft.ReportingServices.Interfaces" in my project and "Microsoft.ReportingServices.ProcessingCore" and I've added 'using' directives for "Microsoft.ReportingServices.Interfaces" and "Microsoft.ReportingServices.ReportRendering" in the code page. Now, according to the MSDN library, the Report object has a property called Body which returns the body of the report as a Rectangle object. A Rectangle object has a property called Repo ...Show All

• SQL Server Red X of death

  I receive the Red X of death when I'm working with SQL Server 2005 community edition. Microsoft Money is causing this to happen. Whenever I move my mouse over an entry in Microsoft Money, I get an OutOfMemoryException and then all the windows in SQL Server 2005 community edition get a big red X. SQL Server 2005 community edition at that point is either not usable or it bombs on it's own. I wrote a budgeting application for my family's use and I was using Access with no problems, but then I upgraded. It's important for me to run queries while using Microsoft Money. Anyway, I'm looking for suggestions to keep this from happening. Here are the details. OS: Windows XP with Service Pack II (all patches installed) Microsoft Money 2 ...Show All

• SQL Server Display a KPI need the same Dimension on its Value and Target?

  I mean, I have a KPI, it's value is set to a measure of a measuregroup based on a facttable A. and it's Target is set to a measure of another measuregroup based on another facttable B. Now I want to display the KPI, with a given dimension's slice. My question is, is it needed that the dimension I chose must be shared by both the measures of KPI's Value and Target For an example, If I dispaly the KPI with the Promotion Dimention, and the Promotion Dimention has a relation to the KPI's Value's related measure(There's a PromotionKey column in facttable A; ), but it has no relation to the KPI's Target's related measure(There's NOT a PromotionKey column in facttable B). Could I do so Thanks! that's what i am looking for! Th ...Show All

• SQL Server Need to prevent database assembly creation

  On certain servers, I don't want developers to be able to create assemblies. Unfortunately, the command sp_configure 'clr enabled', 0 only prevents the CLR-type from being executed, not its creation . I am unable to rename nor put triggers on sys.assemblies, sys.assembly_modules, sys.assembly_files, and sys.assembly_references . I would prefer the user know the boundaries well before implementation. Has anyone succeeded at this Thanks, that helped quite a bit!

• Smart Device Development Initiate synchronization from device

  I have written a C# application for Windows CE, VS2005. What I want to do is to transfer files from the Device to the Desktop PC. It has to be done exactly when I want it to, and I need to know that the sync went alright before my app continue to run. I have looked at "repllog.exe /remote" but it is dependant on the customer clicking the sync button on that dialog window, and not everywhere else (like disconnect). Also, it is one extra step to do for the customer, which should have been done automatically. I also tried importing the rapi.dll from the application on the device like this: [ DllImport ( "rapi.dll" )] public static extern void CeRapiInit(); When I call the function CeRapiInit at ...Show All
