• fuongptit-kodomo Difference in allocating memory when static or local

  I have a static array of struct that I use in a lot of code. Recently I have found need to try and create this variable with an array size over 27M. I am able to do this, as a test, if I create a local variable, but my code requires that it is static and when I try to create it - I get an OutOfMemory Exception. My machine has 4G ram and can easily hold the array. How might I get around this problem Moon Hi what is the value of recsize it could just be that you are running out of memory, so could you not write the values to disk reclaiming them in memory (and disposing of them) as needed That's 10GB of 40 byte records = 400GB. Clearly, that's not going to work. ...Show All

• TalhaAziz How do I force VS2005 to use NET 1.1

  I am working on a bunch of code that was written for NET 1.1 and will not work with NET 2.0 due to changes. It is looking like trying to fix the code to work under 2.0 is going to require more time then I have for this project. So the question is how I can force this code to use the 1.1 libraries instead Thx Joshua Baker Now there is no way to do this. YOu can program for .Net 2.0 and/or .Net 3.0 with some extensions insalled but not for .Net framework 1.1. I would recomd you to upgrade your application to .Net 2.0 or use Visual Studio 2003.

• DotFrammie best practices to secure c# applications

  Hi, I'm starting this thread to hear your experience on the best practices of securing c# applications and code from being reverse engineered and generally jimmied with. Thanks for your input. I think before one can really discuss this topic, you need to clarify what you mean by securing an application. If all you mean is that you don't want someone to reverse engineer the application and reuse your code for their own purposes, thats one thing. If you mean to "secure" it in order to protect the private information that is handled or made available to authorized users through your application, then this becomes an entirely different discussion. I bring this up because, contrary to what man ...Show All

• Peter Kahn Returning Type[] of inherited types

  Does anyone know of a quick and painless way of returning an array of all the inherited Types of a given base class For instance, I have the following: Type myType = typeof(Motors.Motor); Type[] t = myType.GetNestedTypes(); Motor contains many different types of Motors. I understand that GetNestedTypes only returns the classes nested inside of Motor. All I need is a basic method that returns an array of the types which inherit from Motor. I can write this method myself with very little coding, but I figured there had to be something out there that already did this. Thank you many times over for the great explanation, it helped a lot! Even though I'm not very happy about it, at least I understand why I ca ...Show All

• Kesava Assign a bmp resource to a bitmap variable

  I create a resource bitmap as bmp. I can not assign this resource bmp to a Bitmap variable. What I would like to do is change or swap between two bmps every second in a picturebox image. thanks in advance for your help and time, Edward ok the problem was that the image was not embedded as a resource. After changing it to be embedded as a resource, everything worked fine. Once embedded, the resource name will be in the format of, generally, : applicationName.filename.ext if its in a folder (1 folder deep): applicationName.folderName.fileName.ext remember, the folder name and filenames are case sensitive if its under a folder called resource, then im not sure if it will still need to ...Show All

• Speedbird186 Strings

  Hi there I am trying to connect to a SQL database, the default installation of SQL Express installed by Visual Studio Professional. Let me first say I'm coming from a VB6 background, so I know diddly squat about C#. You can consider me a classic case of VDU (Very Dumb User). My main problem is that I am trying to connect to the sql server by using a connectionstring. I am setting the value of the connection string as follows ConnecString = @"Data Source=[GD-MOBILE\SQLEXPRESS];Initial Catalog=PRISM_Test;Integrated Security=true" My problem is that the single backslash is converted to 2 backslashes, and I think this is causing the problem. How do I get just one backslash in there Thanks Carlos I ...Show All

• YoungEngineer Trigenometry Woes

  Greetings fellow coders, I am having a bit of difficulty with coding some trigonometric functions. The primary goal I have at the moment is to find the two unknown angles in a right-angle triangle of which I know all 3 dimensions. While I know how to do this in theory, finding the code to accomplish this is proving difficult. For example: I have a triangle with a base of 6cms, a height of 5cms and thus a hypotenuse of ~7.81. It is a right-angle triangle and thus one of the three angles is 90 degrees. How can I find the other two angles I can't seem to find a Sin-1 function in C#!!! Please note I am using C#.NET 2003, not 2005. Thank you in advance for any help you can give me. However, this only returns in radian ...Show All
