    - by frungash
    I have a dlg box as the main window. After a few searches on the we I tried downloading and running the sample the source here: http://msdn.microsoft.com/en-us/magazine/cc164067.aspx I get a compile error: error C2440: 'static_cast' : cannot convert from 'UINT (__thiscall CStaticLink::* )(CPoint)' to 'LRESULT (__thiscall CWnd::* )(CPoint)' 1 Cast from base to derived requires dynamic_cast or static_cast (VS 2008) The tooltips functionality seems to be a bit of a challenge. Any suggestions on how to get this working are much appreciated.

    - by Roma
    We need to develop guidelines for writing comments when we register code in version control system (such as TFS). E.g., when we submit a bugfix, we create a comment "Fixed bug #..." We tried to brainstorm on this topic, but most of the ideas bring too little added value. I would appreciate any suggestions for this.

  • MVC2 - Dynamic Field Layout

    - by Rob
    I'm new to MVC and ADO.net Entity Framework. Instead of having to create an edit/display for each entity, I'd like to have the controller base class generate the view and validation code based off metadata stored in a table - something along those lines. I would imagine something like this has already been done, or there are good reasons for not doing it. Any insight or suggestions are appreciated.

  • Security issue using Nant

    - by Diego C.
    I need to store authentication information and I rather not have the password in plain text: <property name="user" value="theUser"/> <property name="password" value="secret"/> Has anyone figured out a way to encrypt property values in Nant? I've looked in Nant and Nantcontrib docs but no mention of encryption. I am considering going the route of creating my own Nant Task. Any suggestions?

    - by egiakoum1984
    Need to find a asynchronous DNS resolver implemented in C (except Sofia Resolver) which supports DNS queries for NAPTR, SRV and A records. It would be desired to support internal caching. Any suggestions/recommendations? Currently looking at ldns which supports NAPTR, SVC and A queries. But, If I have understood correctly, it is not asynch DNS resolver.

    - by user252160
    How can I get all custom fields that belong to a certain box only. For example, I am using the "more fields" plugin which allows me to create boxes of custom fields for instance a box called "hotel features" with different custom fields as the particular features. Teh point is that when I extract meta data in the template, there is no way, known to me, how to get only the fields that belong to the "hotel features box", say. Please, help with suggestions

Anyway, I'm in need of a KeyDown handler for the Label Control and would appreciate any pointers/suggestions to get me started. I've searched around but haven't found any info on creating my own Event Handlers for the Label Control. Can this be done is C#? Thanks

  • Parsing language for both binary and character files

    - by Thorsten S.
    The problem: You have some data and your program needs specified input. For example strings which are numbers. You are searching for a way to transform the original data in a format you need. And the problem is: The source can be anything. It can be XML, property lists, binary which contains the needed data deeply embedded in binary junk. And your output format may vary also: It can be number strings, float, doubles.... You don't want to program. You want routines which gives you commands capable to transform the data in a form you wish. Surely it contains regular expressions, but it is very good designed and it offers capabilities which are sometimes much more easier and more powerful. Something like a super-grep which you can access (!) as program routines, not only as tool. It allows: joining/grouping/merging of results inserting/deleting/finding/replacing write macros which allows to execute a command chain repeatedly meta-grouping (lists-tables-hypertables) Example (No, I am not looking for a solution to this, it is just an example): You want to read xml strings embedded in a binary file with variable length records. Your tool reads the record length and deletes the junk surrounding your text. Now it splits open the xml and extracts the strings. Being Indian number glyphs and containing decimal commas instead of decimal points, your tool transforms it into ASCII and replaces commas with points. Now the results must be stored into matrices of variable length....etc. etc. I am searching for a good language / language-design and if possible, an implementation. Which design do you like or even, if it does not fulfill the conditions, wouldn't you want to miss ? EDIT: The question is if a solution for the problem exists and if yes, which implementations are available. You DO NOT implement your own sorting algorithm if Quicksort, Mergesort and Heapsort is available. You DO NOT invent your own text parsing method if you have regular expressions. You DO NOT invent your own 3D language for graphics if OpenGL/Direct3D is available. There are existing solutions or at least papers describing the problem and giving suggestions. And there are people who may have worked and experienced such problems and who can give ideas and suggestions. The idea that this problem is totally new and I should work out and implement it myself without background knowledge seems for me, I must admit, totally off the mark.
