Visual C++ Cannot see the version information in the properties of an EXE.
I am building a C++ project that creates an executable. When I right click and see the properties of that executable, there is no version tab that will give me the version information of that exe. Can you please tell me what I can do so that I can see the version information of my exe. I would like to put the company information, copyright and file versions in that exe. I know you would do that in C# with AssemblyInfo.cs but I am sure about C++. Please help me out. thanks You need to insert a VERSIONINFO resource into the RC file that is part of your EXE. with the resource editor you can easily do this (right click on the RC file in the resource editor and choose "add resource" then choose "version".

SQL Server Encryption Varbinary Length
Using the new encryption included in SQL Server 2005, what is a good way to determine what length I should use for the column For example, I am encrypting a column, its maxlength is about 30 characters, but when encrypted, the encrypted value extends from between 50 and no more than 68 characters- So if I had a column with a max of 500 or so characters, how could I know what varbinary length I should set it to if I were to encrypt it, without actually finding the highest value I could possibly fit into the field Is it good practice to just make it a varbinary(max) field -rob Hey Bob, A lot of factors will impact the performance. Given the dramatic difference in times, I'm wondering i ...Show All
Visual C# Drawing ellipses question
I am drawing a yellow circle but realized I have a problem with it. Graphics g = e.Graphics; Pen yellow = new Pen(Color.Yellow, 3); g.DrawEllipse(yellow, 100, 50, 100, 60); I thought that this was centering the circle in the form at (100,50) while making it's horizontal diameter 100 and it's vertical diamater 60, but I am not sure if this is correct. It appears from what I have read is that the int x, int y positions are for the beginning of the rectangle that forms the bounds of this ellipse. Does this mean that this is the center of my circle or just like drawing a rectangle, it is the beginning from the top left location I want my ellipse centered at 100,50. Is this right What should it look like if it's not ...Show All
Visual Studio 2008 (Pre-release) Identity check failure when using kerberos message security
Hello. I’m getting an identity check failure exception when using kerberos message security to communicate with a self-hosted service. I’m using the WSHttpBinding binding with the following parameters: client credentials set to Windows negotiate service credential set to false establish security context set to false The client credentials have the "AllowNtlm" property set to false. The channel to the service is created with a EndpointAddress containing a UpnEndpointIdentity constructed with “<user>@<domain>” Apparently the security token (a kerberos service ticket in this case) is created, however its claims are not compatible with the identity of the service EndpointAddres and I cannot figure ...Show All
.NET Development AppDomain Unload does corrupt Thread Pool
Hi, I was just trying to run a simple scenario: 1. Create AppDomain 2. Use up all Worker threads from Thread Pool 3. Unload AppDomain before the worker threads have finished. 4. Try to queue another WorkItem in your default or some other AppDomain Result: The .NET thread pool is dead because there are no threads left for the other AppDomain. ThreadPool Threads are not given back to the thread pool when an AppDomain.Unload is performed. I think it is ok to not kill the threads (reliability) but what is not ok is that there are no threads left for other AppDomains. An AppDomain unload should increase the number of worker/io completion port threads which are currently running inside the to be unloaded AppDomain to ensure that you do not run o ...Show All

SQL Server How to specify datatypes for Excel columns?
So I have Excel Source in my dataflow - so I do a simple transform and try to save it to db and guess what - a freaking error message: Columns blahblah and BlahBlah cannot convert between unicode and non-unicode datatype. I cant figure this MS stuff out - why the heck is this data from excel unicode to begin with & I just dont feel it is right to always use the derived columns to convert datatypes when dealing with Excel data.
