• .NET Development appsettings and adding keys programatically

  I'm trying to add keys from one Web.Config to another without success. keeps popping out with a ConfigurationErrorsException. I'm traversing throgh the AppSettings section of one web.config and adding the key and value found for each element into the AppSettings of another WebConfigurationManager (I was hoping that this could be done in memory instead of writing to the web.config and saving). Why can I not add to the AppSettings [CODE] try { // Get the application configuration file. Configuration ourConfig = WebConfigurationManager.OpenWebConfiguration("/mdserver"); Configuration serverConfig = WebConfigura ...Show All

• Visual C# windows form - zoom

  Ok, i'm trying to find a way to be able to zoom in and zoom out on my picturebox object. I have a windows form with a panel in it and have my picturebox object inside my panel. I have found a solution here: http://www.codeproject.com/cs/miscctrl/zoompancontrol.asp which works pretty well with only the picturebox. My problem is I need a zoom that will not only zoom in/zoom out my picture but will zoom in and zoom out all of my drawing in the picture. When i'm talking about drawing I mean being able to add some square, circle etc on the picture (similiar to mspaint). At the moment, only my picture get zoomed and not my drawing. IE: ...Show All

• Visual Basic Split a read-in string into more variables or read individual characters

  I am extremely new to VBA, so I'll need some detailed answers. Any help is more than appreciated. I have an input box that reads in a set of 3 characters separated by a space like this:  A1B 2CD EF3    called Values I then read a 3 character value from an Excel spreadsheet (lets call it Initials) and want to compare this with the read in values.  Easiest way, I assume, would be to compare Initials to characters 123 of Values and then compare Initials to characters 567 (since 4 would be a space) etc. Can I do this and if so how If not, how do I split Values into 3 separate variables so ...Show All

• .NET Development Remoting-v-webservices - the prescriptive guidance is nuts ?

  Web-services excel for cross-platform/cross-language communication. However, what about communication for the internal tiers of an app, where it is .NET on both sides It's the endless debate of remoting-v-webservices. Remoting - faster performance and richer type system, versus the lower-performance, lowest common denominator of web-services. The message that I perceive from MS is "use web-services for everything - remoting is only for in-process, cross-app domain communication", but as Rocky Lhotka suggest "the prescriptive guidance is nuts." http://tinyurl.com/5wnul So, is the "politically correct" choice of web-services really that ...Show All

• .NET Development Problem with 'Oracle client' and 'ODPnetOnly'

  Hi all ! I have both Oracle Client and ODPnetonly on my system. They have their different homes. If the path of Oracle Client (D:\oracle\ora90\BIN) is before the path of ODPnetonly (D:\odpnetonly\bin), then I have a problem. In this case, my web applications (in C#.net) don’t work but my console applications (in C#.net) do. And if I change the path of ODPnetonly before the path of Oracle, then my web-applications work but my console applications don't. So please tell me what is wrong with my system. Is there any problem regarding installation of 'Oracle Client' or ODPnetonly (I installed 'Oracle Client' before the OD ...Show All

• Visual C++ optimization issue with VC++ 6 SP6 compiler

  Can anyone explain the following behaviour I am using VC6 with SP6. The following code is producing different printf output if I use different optimization options in release program. It seems that the difference is caused by initialization of the member variable called 'packlength'. If I replace it in function max_length() with constant then program produces correct output. Correct output is also generated when I build this program with Microsoft Visual C++ .NET 2003. typedef unsigned int uint; typedef unsigned long ulong; typedef unsigned __int64 ulonglong; #define BLOB_PACKET_MAX_LENGH(arg) ((ulong) (((ulonglong) 1 << mi ...Show All

• Windows Forms Weird behavior when customizing property grid.

  Hello guys, I'm studying the architecture behind custom controls and the property grid in 2.0 for a while now, but I still not seem to get it completely. I've tried a couple of strategies, which all resulted in some undesired behavior that I cannot explain. I hope someone can help me out and provide me with the missing details. Strategy 1: ICustomTypeDescriptor I linked an extension of CustomTypeDescriptor to my custom textbox through a TypeDescriptionProvider. In this extension I have overridden the GetProperties method and I return only the properties I want the grid to show (say Name, Location and Size). Having done this I enc ...Show All

• Visual Studio Team System Possible to detect use of enum.ToString()?

  Does anyone know if it is possible to detect the use of an enum's "ToString()" method The reason I ask is because we have started obfuscating our code using Dotfuscator, and of course because that renames the enums, it plays merry hell with any use of enum.ToString()! It'd be great if FXCopy could detect such usage. Also, I guess we'd need to detect enum.Parse() and other reflection-style access. Any help would be much appreciated! Just to follow this up: I used Michael's source code to solve the problem - thanks Michael! I also had to add a rule to detect the boxing of enums, because you can pass an e ...Show All
