  I received a public key in plain text from someone. I would like to encrypt a text with the following code, but I receive an error "Invalid syntax on line 1" at rsa.FromXmlString.

• SQL Server Writing Query To Dynamically Select a Database Table

  Is there a way I can write a query to dynamically select a database table. That is, instead of having a variable for a certain column like customerId which would be “customerID = @customerID” I want to use the variable to select the table. I assume I may have to use a stored procedure but I am unclear as to how this would be coded. Thanks hi kevin here's some code to start with use northwind go alter proc dynamicselect ( @Mytablename nvarchar(30) ) as declare @cmd nvarchar (2000) select @cmd = 'SELECT * from '+ @Mytablename exec (@cmd) go exec dynamicselect employees exec dynamicselect customers however i suggest you consult this link http://forums.microsoft.com/MSDN/ShowPos ...Show All

• .NET Development DLL loaded twice

  Hi, I was looking at DLLS used by a process using ProcessSpy and found that the process has loaded two DLLs for few of the system dlls like Systsem.Drawing.Dll, System.Windows.Forms.Dll etc. For one of these DLLs the version is 0.0.0.0 and the other one has a valid version. Unfortunately, I can't add a snapshot of the window here. What I am wondering is, whether its pretty common to have this behavior or something is wrong in the taks, the way it is loading DLL. Thanks, -Brajesh Your guess might be right, as I see that the version 0.0.0.0 is being loaded from C:\windows\assembly\nativeimages1_v1.1.4322\system.windows.forms\1.0.5000.0__b77a5c561934e089_fa580ca7 and the other version is b ...Show All

• Visual Basic Dynamic Memory Allocation in Visual Basic

  I am new to Visual Basic, but have had some training in C++. I was working on a program in Visual Basic 2005 where I need to allocate memory to an array dynamically. The array is to be of type ButtonRow, (which is a class I've created for this program). I want the size of this array to equal the total number of rows in a given table. I can figure out how many rows are in the given table, and store that value in a variable (MaxRows). I need to dynamically allocate the ButtonRow array with the size of MaxRows. How do I do that in visual basic Is there a Visual Basic equivalent of the calloc and malloc commands Also, just to give you guys a complete picture, the ButtonRow array is to be a universal array available to all subs within the gi ...Show All

• SQL Server problems at beginning of set up

  Before I get into the project that I actually need working I'm trying to get through an example or two provided by microsoft. I'm using the Flights sample from http://msdn2.microsoft.com/en-us/library/ms160889.aspx I've downloaded the files and follow the instructions but quickly ran into trouble. I select the configuration file, enter the needed information, check the 'enable instance after it is created' box, and click okay. This takes a couple minutes but finishes without errors. I then try the register step. I enter my login information for the computer I'm using and use windows authentication. After click okay here's the error I get: Registering Instance - FlightInstance - Updating registry entries (Success) ...Show All

• Visual Basic AllowLaterVersions and forward compatibility

  I am setting up my first deployment project on VB.NET 2005, and I'm getting a warning that concerns me. I saw the AllowLaterVersions property of the Framework. This seemed obvious to me that it should be turned on, since I do want this application to still run in the future, as new Framework versions are released, and the user installs them. And, I am assuming MS will make them forward compatible. I also get an error on build about this, noting that the project contains a managed custom action. Am I interpreting this property correctly By default, the Setup program will not run if the .NET Framework 2.0 is not installed, even if a later or earlier version of the ...Show All

• Visual Studio Team System Long file names?

  Hmm, getting a lot of errors on schema import like this: Path for file C:\Documents and Settings\Highway\My Documents\Visual Studio 2005\Projects\Highway\Highway\Highway\Schema Objects\Tables\tblwFinancialTransactionActionReasonLookup.FK_tblwFinancialTransactionActionReasonLookup_FinancialApplicationId_tblwFinancialApplication_FinancialApplicationId.fkey.sql is too long. Yup, sounds quite long. Does this mean it didn't import it, or has it secretly shrunk the filename and imported it Sadly, it looks like your running into a limitation of MAX_PATH. That full string is 289 characters long. You'll need to move your project out of Documents and Settings. Cheers, Brian Randell MCW Technologies ...Show All
