• Visual C++ Visual C++ 6.0 and Visual Studio .NET

  I have an old program (I programmed quite a long time ago with Visual Studio 6.0) that i want to transfer to Visual C++ .NET however, i have since lost the source code to it. Do you know of a de-compiler that i can use on the .EXE file that will give me that source code Thanks in advanced. D. Rux Dan Rux hi, I am afraid that there is not a way to get your source code from the .EXE file. The only thing that you can obdain from any .EXE file is only assembly language code (useless i think) and i am not sure if this can be done by Visual Studio. ...Show All

• .NET Development Why does System.Drawing.Rectangle become ValueType?

  Hi all, I have a managed C++ class library I use from a C# program. All of the functions that take or return Rectangle, RectangleF, or other structs now take or return ValueType. Why is this and how can I fix it The Rectangle and RectangleF types are simple struct declarations. In the .NET CLR, structs are value types. They get allocated on the stack instead of the managed heap, giving Java a nice kick in the pants. Conversion to a reference type (or Object) is automatic through a process called 'boxing'. That has a few nasty side-effects that every .NET programmer should know about. Getting to the point: what is your problem ...Show All

• Visual Studio Tools for Office Excel automation question

  I am trying to programatically delete all rows that have been filtered out with an autofilter in an excel spreadsheet. I can find a lot of examples of how to delete rows that have not been filtered out, but I want all "hidden" rows deleted. Any ideas Hi Mike The best place to get help with a basic automation question is the excel.programming newsgroup. The folks there are VBA-centric, but they really know Excel inside-out. This forum is really dedicated to the VSTO technology, although object model questions do get answered, on occasion. But your request is so specialized, you should go right to the experts :-) If you're programming in C# and get some VBA code you can't get to work, feel ...Show All

• Smart Device Development Does CF2.0 have a Diffie-Hellman key exchange protocol implementation?

  can anyone post some related materials or links about it many thanks! Hi AFIK the .NET CF 2.0 does not support this out of the box. But the underlaying Windows Mobile OS (part of the CryptoAPI) does support two Diffie-Hellmann protocols.

• .NET Development MSHTML problems.

  I wrote a program that crawls a particular webpage using mshtml.dll and interop.shdocvw.dll. It creates a web browser object and then navigates through a couple pages. It works on my computer and most other newer computers that I try it on, but on some computers it crashes near where it uses the web browser object. It crashes on a computer that is running XP, .NET 2.0, and IE 6.029. All of those specs are the same as on my dev computer (which it works on). I also include the shdocvw.dll with the program when I give it to people to try. Does anyone have any idea what is missing which is causing it to crash This forum is dedicated to questions about the System.Net namespace. Please see http://www.microsoft.c ...Show All

• Internet Explorer Development using a scanner with Ie.

  I have a rather complex little problem facing me.  The company I work for implements a CRM application that is purely a web application.  We have clients that use a Card Scanning Solutions license scanner to gather information about the customer.   I need to make the following happen. User logs into an ASP or ASP.NET 2.0 site.(we have two versions of our application) User clicks a button on an IE toolbar and a dialog is displayed that prompts them to insert the license into a scanner. Clicking through this dialog makes a call to the Card Scanning Solutions license scanning SDK which is registered as a COM object on the user's system. The scanner returns information read from the license to IE and IE closes t ...Show All

• Visual Basic save file on another have the same name :"overwrite"

  hi : how can i save file overwrite on the another have the same name When you are directly pointing the panel's backgroundimage to a file, then you are creating a connection between the two so when you then try to overwrite that file, you get an error because the panel is still using the file as backgroundimage. So you need to make sure that no link can occur - in the example, I use a copy of the bitmap-from-file and make sure that the bitmap-from-file is disposed (=destroyed in memory) before using the copy as the backgroundimage. I'm assuming you want to paint something onto the panel(and its background) and then use the BitBlt operation to copy the result to file, but you can do that with managed co ...Show All

• Software Development for Windows Vista transactions and ExternalDataExchangeService

  I have a state machine workflow that represents my process. At a pre defined time, a bunch of instances get kicked off. Then individual users interact with specific instances to move them through their states. Finally, at another pre defined time, I need to complete all the instances, followed by running a stored proc. To complete the instances I can just iterate through all the active ones and raise my ThingyCompleted event in my ExternalDataExchangeService. The trick is that I want all the event raising and the execution of a single stored proc to all happen in the same transaction. Since the stored proc is basically a rollup and needs to happen after all my workflow instances complete, it has to be run from the host (as opposed to ...Show All
