• .NET Development Why develop in 64Bit

• Visual C++ Win32 under DLLs?

  I'm fairly new to DLL building and have what I'm sure is a dumb question, but I can't seem to find a solution anywhere: I've dynamically linked to the DLL, the test calling program has no complaints and both tester and DLL compile cleanly. However, as soon as I hit a Win32 call in the DLL the program GPFs. It doesn't seem to matter which Win32 function I call - the call itself is resolving to an access violation. I've looked at the addresses called, and they point into empty heap. Somehow all my Win32 functions are being lost. Does anyone know how this could happen Entomophobic wrote: I'm fa ...Show All

• Visual C# What benefits do XML documentation comments offer?

  I am developing a couple of small apps for a client, and I am considering ways to document the code. If I use XML comments, I understand that a 3rd party utility is necessary to view the raw XML in a pleasing style. Unfortunately, I'm not using such a utility while developing these apps. It may be that I'm getting crotchety as I age (oh, I hope not), but I find raw XML comments harder to read than the well-formatted C++ comments to which I am accustomed. Without a 3rd party utility, are there still benefits to using XML comments vs. non-XML comments Thank you for your suggestions. To clarify: If I we ...Show All

• .NET Development Importing Encrypted Web Data to Local Database

  This is completely outside anything I've ever worked with, so please excuse me if this isn't the right forum for this question: Our company uses an encrypt/decrypt component on its website that functions perfectly provided you only use it AT the website. I've been asked to link an Access 2000 backend to the web data, so I need to be able to decrypt the encrypted strings in-house and haven't the first idea of how to accomplish it. The component is called DyncuEncrypt ( www.dynu.com ) and they offer this code on their site: Set oEncryptor = Createobject("Dynu.Encrypt") Dim sEncrypted, sDecrypted As String REM Encrypt t ...Show All

• Visual Basic How does VB compare to C# part 2

  I am sorry but my question was NOT answered at least not technically. But, what is clear is that there is a lot of strong feeling against VB's syntax that does not exist against C#. Several post indicated that they would not hire a VB programmer unless they programmed in C# syntax. I really find that disappointing. I thought the purpose of the framework having several syntaxes was to promote choice for the developer and make that choice seamless to the end user. But I am not certain MS is committed to that point. Several conferences that I have been too, the audiences has shouted down examples in VB and insisted they be presented in C ...Show All

• Visual Studio Error: "data\rights.dat is already open"

  Hi, I've just installed Visual SourceSafe 2005 on a Windows XP Professional SP2 machine. I'm not sure right off the bat if that's the problem because scouring the web, I've not found any location that lists the system requirements for this software. In fact I can't even find the official Microsoft Page for this program! Is MS downplaying its existence to get people to migrate to TFS Anyway, after creating the SS database, I tried to add a project to the source control on my laptop through the LAN (also running xp pro SP2), but when I try to connect, I get the error "File C:\Documents and Settings\<username>\My Documents\Vis ...Show All

• Visual Studio How to determine the type of build being executed in the BuildEvents_OnBuildProjConfigBegin handler.

  I am writing a macro that I want to execute when the user choses any Build command, except for any of the Build.Clean... commands. My question is how to determine what Build command the user has chosen within the BuildEvents_OnBuildProjConfigBegin handler I am using Visual Studio 2005. Thanks in advance, Jim PS> I tried catching the CommandEvents_BeforeExecute event. But, for whatever reason, the event is not being called.      Connecting to command events is the best method, and it should work.

• Visual Basic Combo boxes in datagrid view give errors when closing form (VB 2005/.net2/sql 2005)

  Hi, Althiough an experienced programmer (20+ years) this is the first time in 10 years that I've had to use VB so apologies if obvious answer. I'm using a combo box inside a datagridview. The combo works correctly pulling data from lookup table and placing it in the grid table. I can save the data okay. I can exit the application fine, but if I try and close the form either programatically or using the close button on the form I get an error that the values in the combo box are invalid. This occurs after the FormClosing event is fired. Anyone else seeing this or know of a workaround. It didn't occur in the VS 2005 CTP but does in the ...Show All
