• SolveIt A problem in transffering data on a cross platform

  Hi, I am calling a 2.0 functions from 1.1 through a bridge (using com+ server ). My object implements 2 different interfaces .Each of the interfaces has one function that works with the same global parameter. My client calls the first function by casting to the first interface that contains it. This function inits the global param. Then, I cast my object to the second interface in order to call to its function. This function uses the global parameter but from some reason it is null. as if it was recreated or override. The code looks like : private Type mBridgeType = Type.GetTypeFromProgID ( "SPL.ProjectWrapper.CrossFrameworksBridge" ); private ISourceController mBridgeObject; private ISourceControlEr ...Show All

• RobinSpicer "Plus equals" pattern in IL gives incorrect results

  When people claim to have found a bug in the CLR, I am normally the first person to tell them to go back and find the bug in their own code, since that is far more likely than the problem being in the CLR itself, given how stable the runtime has been since its release. However, I believe I have isolated a case where the runtime, or something operating at or below the IL level, is behaving incorrectly. (Note: the problem I describe here only occurs in version 1.1 of the CLR; version 2.0 does not appear to be affected) This case evolved from a bug I was having in a VB.NET app, but after disassembling the app and playing with the IL code, I am confident that the problem has something to do with the IL itself. Basically I am performing a "p ...Show All

• geertdeprez Get Hardware Detail from Drive Letter

  Hi all, May i know how we can get hardware detail from a Drive Letter by using VC++ .Net Hardware Detail are like GUID, Hardware ID, Friendly Name and etc. Regards in .NET 2.0 you can use the DriveInfo class to get a list of all drives installed or mapped on the system. Example: DriveInfo[] theDrives = DriveInfo.GetDrives(); foreach(DriveInfo curDrive in theDrives) { MessageBox.Show(curDrive.Name); } away from this....and into WMI. I see DiskDrive class has the DeviceID and the LogicalDisk has the Name. So somehow you need to perform some similar SQL Join statement or something. Ill see what I can try look in the Win32_DiskDrive class :-) http://www.microsoft.com/downloads/de ...Show All

• Vjy String concatenation performance comparison

  Hi ppl, a simple question here, consider the two options = String.Concat("string1", "string2", "string3"); and = "string1" + "string2" + "string3"; which one will yield a better performance As I know, string is immutable, so, we cannot change the value inside it without the CLR creating a new string. So in this case, would the second case create a new string for "string1" + "string2", before using this new composite string to concatenate with the "string3" How about the first option, would the CLR actually create just a single new string as the system already know the total number of strings to concatenate Pardon me if I got my syntax w ...Show All

• StephenWalker Performance in DotNet remoting

  Hi, Application: We have developed a DotNet Remoting application which acts as a server to Calculate analytics. This server takes inputs from different client applications and respond with the analytics. This server is run on a "Single-call" mode so that each request is created independently for scalability. In some scenarios the requests from the client are sent parallely using different threads to speed up the process. Also, this remoting server uses some third party libraries for calculations which takes a longer time to compute the analytics and these libraries do not support multi-threading. Problem Statement: - Keeping number of users and different requests, Request / Response volume is very high. There are case ...Show All

  Hi, My program has to sumbit some data to a website and read the result form it. This process is to be repeated continuously using different sets of data. My problem is that when data is submitted using the following code, it produces an UnauthorizedAccessException at line 70 ( htmForm.submit(); ) when the for loop is in 3rd or 4th iteration, and it never recovers.

• bzoli Creating XmlTextWriter with Formatting.Indented, and Settings.OmitXmlDeclaration=true

  Hi! I want to create a XmlTextWriter object which I can pass to the XmlDocument.Save() method. In the XmlTextWriter class, I want Formatting = Formatting.Indented, and Settings.OmitXmlDeclaration = true. i'm not able to find a way to do both. If i do: XmlTextWriter x = new XmlTextWriter(), then I see that x.Settings == null, and plus its readonly. if i do: x = XmlTextWriter.Create(stream,settings), then "x" is not a XmlTextWriter, but some other class which does not have the Formatting property I'm hoping someone here can help me ..

• RhysDavies Problem with StreamReader

  I'm have a problem with the StreamReader that I can not figure out. As I have it set up right now, it will read through a text document. The text documents are created through our network backup utility. The problem that I am having is that when I run the program I am getting "Object Reference not set to an instance of an object". But if I open the text document manually and hit save without modifying the document at all, then the program run perfectly.

• JustinA1 Out of memory exception (c#, .net 2003, large images)

  Hi, I am developing an application (c#, .Net 2003, Framework 1.1) that deals with large images. The application captures multiple image frames and stitch them up into a large hige-res image. We are looking at 50+ frames and sometimes more than 100 frames of 1024x768 color images. I am also using double buffers for edit purposes. To get an idea of what this application does: beyond the image acquisition and stitching, it is very similar to Paint.Net ( http://www.getpaint.net/index2.html ) in providing tools to draw on top of the image. The program is hitting out of memory exceptions -- sometimes even with smaller images. Documentation on LOH seems to explain this observation well, especially with memory fragmentation a likely cause of ...Show All
