• Windows Forms Combobox Usage VS2003 -> VS2005

  I need to populate a C# Combobox with potentially several thousand items. I know this is not recommended but this is after horiz data splitting so it's the best I can do. In VS2003, I tried binding to a dataset but this was way too slow so I started loading the Itemlist from a datareader and it worked great. No more than 2 seconds to load several thousand items and memory usage stayed well within reasonable limits. I tried the same code compiled under VS2005 hoping to use Autocomplete and it worked well for very small lists but was many times slower for the normal lists I use. Several minutes compared to a couple of seconds. Additionally, th ...Show All

• Smart Device Development using in evc4?

  Hi can i use evc4 for debuging and running applications on device emulator as i cannot connect through it... regards The device emulator can act as a "real" device by connecting it through ActiveSync. I n ActiveSync, make sure that "DMA" is selected in the "Connection Settings".  Then, using the Device Emulator Manager, connect to and cradle a device emulator.  You can find the Device Emulator Manager in \program files\microsoft device emulator\1.0\dvcemumanager.exe.  This will create an ActiveSync connection with the emulator.  If the connection is not created, you can use the "Get ...Show All

• .NET Development how to prevent modification(deletion, rename) to an assembly?

  hi , suppose i have an application which uses a assembly "***.dll" and it loads the assembly using reflection and creates a object of it that too using refelection. now i want that if the assembly is loaded nobody should be able to delete it or rename it.how can that be done.more specifically how to lock that particular assembly dll. thanks and regards ramneek .NET does not provide that type of security.

• Visual C# How do I access the application Form Name?

  Please excuse this question.  I'm currently learning C# "on my own".  My application is an MDI with several child forms and I want to enable/disable the buttons on the active form by calling a method that will accomplish this for each form that calls it.  I created a test app and thought I had the solution; however, I am at a stopping point and can not figure out how to solve this.  Can someone please show me what I am not doing  or doing wrong   I've included the code from the Class and from one of the calling methods below (the code is C# 2005): Code in ClassMain.cs:     public vo ...Show All

• Visual Basic strange bracket problem

  Hi, I've been finding that randomly, after building my project, the editor will start inserting brackets as I type. For example: I type "a" - it changes to "a()" I type "try" - it changes to "t(r)y" I type "ng.Save" - "n(g).s(a)ve" I've disabled Edit and Continue, but still have the problem. The only way to get round it is to restart visual studio. I've had the problem on two computers, and another programmer here has the same thing happen too. I can't find any information about this on the web, and I'm not really sure what to search for in any case. Hi, thanks for your answer ...Show All

• Visual Studio launch a popup window during a POST BACK?

  Hello All, I have a SSRS 2005 web application that utilizes the ReportViewer control for ASP.NET.  I have my Report Display page as a separate page in my application.  Whenever a user wants to view a report, this page is to be launched in a new browser window and displayed to the user.

  Hi, I need to verify that when the page is displayed there's a certain image present on it. It sounds like this should be easy, but I am having problems with it.

• SQL Server Import data from Excel?

  Hello, I have an Excel spreadsheet that I am loading data from and I want to prevent SSIS from making assumptions about the data contained within the spreadsheed and to just treat every column as a string (i.e. Unicode string [DT_WSTR]). How is this done I know I could do a conversion once the data is loaded, but I am wondering if there is a way to specify this in the Excel Source settings without having to add a Data Conversion task to the Data Flow. TIA... As far as I know, this cannot be done. You are allowed to set data types in Flat File Sources and delimit them by a comma, though. Maybe you could export the excel file ...Show All
