• Visual Studio 2008 (Pre-release) Absolute path in XAML... how to avoid them?

  In an application I create a Xaml file and some referenced local _files_ (images, etc.) in the same folder of the xaml file. The xaml and the other files are dynamically created/read/ written , so they can't be in the program files folder and must be somewhere under the user Documents folder. The problem is that the user could move those files into another PC/folder and the referenced path inside the xaml would be wrong. Hypothesis and problems I found: 1. specifying relative path in the XAML tags (i.e. Image). As far as I can see, relative names are used to look into the resources and not in the file system. Furthermore, once xaml is loaded, there is noway to keep memory about the folder from which it was loaded (and that's corre ...Show All

• .NET Development What is the List<OdbcParameter>.Enumerator?

  I'm having diffuculty with a memory leak that appears to be related to the System.Data.Odbc class. When the OdbcCommand class is disposed the List<OdbcParameter>.Enumerator classes are not being disposed. Using a memory profiler I can see undisposed instances of them continuing to increase through all the garbage collection cycles. Does anyone know how to get these to release with the other OdbcCommand resources What is the List<OdbcParameter>.Enumerator I'm using .NET 2.0 to connect to a MaxDB database and call a stored procedure via the ODBC data provider (System.Data.Odbc). Here is a piece of example code: OdbcConnection dbConn = new OdbcConnection(connStr); dbConn.Open(); for(int i=1001; i<2001; i++) { ...Show All

• Smart Device Development Libraries for Win Mobile

  Hi there. I've had some trouble with an application I'm working on. Hope you can help. See I'm using a library that uses sys/types.h library among others.

• Visual Studio Express Editions Look-up table :-

  I need to do manipulation with my incoming data fr serial port n need to have a look-up table for this purpose, starting from 0.0dB and 30H data. For every increment of hex value, the level increases by 0.5dB. My data in hex format, i need to convert it to dB value based on the look-up table. How can this be done Disclaimer: I am no good at math and can't handle 'log' functions in math. Anyway the math in the following may be all wrong but maybe it will give you something to work with.

• Visual Studio Team System FXCop looks for references.. Why..???

  Hi, We are trying to run fxcop on our application, but then it asks for all the references used by that dll throwing the CA0058 error. Why is this so. Aren't we supposed to be doing static analysis of the code that we wrote Then why the need to check all the references. I understand I can fix this issue by pointing to all references, but I still would like to know y its needed Thanks for your assistance, Regards, Ramya You are right, we only analyze the code that you wrote, however, we still need to know about base classes, attributes, parameters, return types, etc that live in other assemblies. Without this information, we couldn't make security judgements (as base class' could be applied ...Show All

• SQL Server ALTER DATABASE MODIFY NAME but

  Leave the file location/directory the heck alone! How do I do this Just issuing: ALTER DATABASE Old_Name MODIFY NAME = New_Name moves the mdf and ldf files to a new, unwanted location (apparently the SQL Server default as it's under program files) with the new name. Is this possible or do I have to issue the additional ALTER DATABASE MODIFY FILE statements for this modify name does not move the file(s). create database [test] on(name=test,filename='c:\test.mdf') log on(name=test_log,filename='c:\test.ldf') go alter database [test] modify name=newtest go select * from [newtest]..sysfiles go drop database [newtest] go ==result== 1 test c:\test.mdf 2 test_log c:\test.ldf ...Show All

• Software Development for Windows Vista Interacting with different users based on roles

  Hello, I've designed a document validation workflow but still with no roles on it, so anyone can introduce a document and anyone can validate it. I've been searching info about roles and what I've seen is that you can say which roles can or cannot do an activity. But my application is a bit different: There are 4 different roles (ranks of the employees). Role 5 (the less "important") can post a document, that same user can modify it as many times as he wants and then send it to validate, and it has to be shown in the list of pending documents of role 4. But role 4 can as well post a document that has to be validated by role 3, and role 3 need validation from role 2 etc. I suppose there has to be a way of designing a sing ...Show All

• Visual Studio Using ReportViewer Control into a WSS Web Part

  Hi all, I already posted this thread in the WSS.Dev newsgroup but I got no answer. So I'm trying here. I would like to have the ControlViewer control loaded in a web part but I keep having an error when the Web Part is loading. I tried with other 2.0 controls and it worked properly I just can't make it work with the ControlViewer. I have removed all custom code in the web part. The Web Part only contains the ReportViewer Control and that doesn't work. The error iccurs on the PreRender event but I couldn't find why.

• Smart Device Development Register and unregister DLL

  My C++ smartphone app automatically registers (ala regsvr on your desktop) at deployment because in the project's properties configuration page for deployment I have "Register Output" set to yes. What executible is this calling to register the dll I cannot find regsvr.exe or regsvrce.exe or wm5_regsvr.exe or any other variant on my phone. The reason I want to find it is I want to unregister the dll to clean things up (kind of like a clean deploy). I am using a Motorola Q, if it matters. Thanks, Ed I looked around the WM5 SP SDK and did not find such a tool, so you may have to write a reg/unreg tool. I routinely use the code snippets on that article to register / unregister DLLs from within an application which ...Show All
