• Visual Basic PropertyGrid problems

  Hi, I am currently using the propertygrid control to browse an object containing many properties of different types, some being structures which contain properties of their own. The first problem is that when I create a class inheriting from ExpandableTypeConverter, and use this class as the type converter for a property in my base class, I cannot find a way to unbold the display text using the DefaultValue attribute... The second (more important) one is when I have one of these property (of the type of a user-defined structure) and I try to edit a property of the base property it does not change...The base property get m ...Show All

• Visual Studio Express Editions Decompile Prevention.

  Do you know if any ways to prevent my executables from being decompiled My 5 year old does this. She asks me a question, then says 'how do you know' There is a tool that will compile your .NET app to machine code ( not MSIL ) and therefore is as safe as C++ code. Given that you're posting in the Express Edition forum, I assume you didn't pay for a compiler, and this tool is probably outside your price range ( it costs a LOT more than visual studio does ). It's also a bad idea, IMO. If you want safe code, you need to use C++, simple as that. There are things you can do to try and help the situation, but you can't stop people from de ...Show All

• .NET Development Rendering Text from a SVG file

  I have problems rendering text from a SVG file in C# at the correct position. What is the correlation between the x, and y position attributes in the SVG file and the "origin" parameter in the GDI+ method GraphicsPath.AddString(...) Simply putting in the values from the SVG file shifts the rendered text. I don't see any other simple relationship either, like the origin beeing defined in the bottom left corner and the GDI+ window having it in the top left or something like that. I just noticed now that it might have something to do with the StringFormat tag in the AddString method. If I use StringFor ...Show All

• Visual C# FileInfo.LastWriteTime issue: does not correctly evaluate

  Hello All, I'm currently having an issue when evaluating FileInfo.LastWriteTime between two files.  Basically, the two files in question have the IDENTICAL LastWriteTime values, however the following code evaluates to false: FileInfo f1 = new FileInfo ( "C:\\FileTest2\\IUS_GEN.MNV" ); FileInfo f2 = new FileInfo ( "C:\\FileTest2\\SubFolder\\IUS_GEN.MNV" ); f1.LastWriteTime == f2.LastWriteTime //this evaluates to false Strange thing is, if I convert LastWriteTime to string, it evaluates correctly, as in: f1.LastWriteTime.ToString() == f2.LastWriteTime.ToString() //this evaluates to true! Both files have the ...Show All

• Visual Studio 2008 (Pre-release) "late binding" communication and more questions

  I have several more basic questions concerning indigo: 1. Does the WCF provide a way to communicate to a slick way to communicate to a web service which is discovered during runtime. As an example: somebody provides a WSDL and an operation he wants to call from this service as well as a XML message he sends to the service and a XSL that he wants to apply to the response message. Currently I do something like that with a manual HttpWebRequest. Is something like that possible with WCF in a better way or is the contract/a known interface a requirement for WCF communications 2. Is WCF supported on the Compact Framework or will it be 3. ...Show All

• .NET Development IPermission.Demand not called

  I've implemented an IPermission derivative and a corresponding CodeAccessSecurityAttribute class. I register my class with caspol and gac it. My test driver has a method I attribute with my CodeAccessSecurityAttribute and request SecurityAction.Demand. Just prior to making the method call, I see the constructor for my permission class is called, then FromXml() and IsSubsetOf. Demand() is never called. Why Curiouser and curiouser...  I see the Demand call even with that attribute.*  Given that the problem doesn't seem to lie in the code, I guess we'll have to fall back on possible registration issues.  Try adjusting the ...Show All
