• Visual Studio Custom Data Visualizers

  I have seen the Custom Data Visualizers and I attempted to create one but I found the sample to be extremely lacking (or perhaps I am thinking lightyears ahead of the plans of the VS.NEt team again) A sample of what I wanted to do was I wanted to be able to build into vs.net such that the data visualizer for something like a hashtable. would have an extra row. And when this row was expanded it would display 2 columns. Column 1 would show all of the keys and column 2 would show each object associated with the key. A more advanced sample would allow one to expand the object used as a key or the object used as the value. (I somehow get the fee ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. The COM-based CORE engine (a lot of questions)

  I'd like to discuss a creation of the core engine for our future projects. I chose this forum not accidentally, I hope that professionals (especially from Microsoft) will help me in my questions. First, I'll say a few words about the core engine. It provides system, input, video and audio core techniques. Also, it has a pluggable system. The main COMponent 'MWCore' (from 'MWCore.dll' server) is only the bridge which connects the parts listed above together with the game. So, it's something like an abstraction layer between the operating system and the game engine. There are following main interfaces: IMWSystem - window handling, ...Show All

• Visual Studio error MSB3323: Unable to find manifest signing certificate in the certificate store.

• SQL Server Using a parameter for the "IN" clause

  All, Having some trouble with getting the "IN" statement to return results from a stored procedure. I want to pass in a string of values, such as ('999999', '111111'), to my stored procedure and use it in a select statement.

• SQL Server Running SQL server 2000 & 2005 side by side

  Hai My system is already installed with SQL server 2000 . Is it possible for me to install SQL server 2005 BETA CTP in the same machine and run both side by side. Regards   I am not sure which CTP you have, since we have RTMed SQL 2005, it would be better if you want to evalute SQL Server to install the full SQL Server 2005 Eval version.  Depening on which Beta you have, side-by-side installations may or may not work for you.     ...Show All

• Smart Device Development phone.dll: MakeCall fails on new qtek (v5 3g wlan keyboard phone) !! LEVERAGE !!

  Hello. I have a problem on a new device. It is a new QTEK with keyboard. phone.dll - MakeCall("don't ask before calling") places the calling dialog so that the center of it is at a vertical position 2x what it should be, before the dialog hangs. My app is orientation and resolution aware, and the problem is the same no matter what orientation I use. This is a breaking change from emulators and (multiple) earlier phone and pocket pc versions, including Qtek 2020, which I know others have had problems with MakeCall() on . Please help! I discovered this problem too with the iMate JasJar device, I've reported it ...Show All

• Visual Studio Team System Undoing a changeset?

  How do you back out of a changeset   I was experimenting with branches and merging and I made on a change on a branch when I intended the change for the trunk version.  BTW, I can see this being a problem because the VS editor MDI tabs only give a filename (not directory) and so does the solution explorer.  It would be nice if there were some visual cue to indicate that a solution you have loaded is not the "primary" version you work with but a branch instead. Keith, To add to my comments in repsonse to Carl's feedback, rolling back a changeset (revert as we called it) will certainly be conside ...Show All

  Hello, I am working with OleDb to perform a bulk insert from a temporary table to permanent database table, both of which belong to the same database. I am wanting to use "INSERT INTO <permanent_table> SELECT * FROM <temp_table>". The query I run in MS Access to perform this bulk load does process correctly, but not in code using OleDb. After properly setting up my OleDbConnection object, opening it, and properly creating my OleDbCommand object, my question is this: when I call "ExecuteNonQuery()" no rows are returned and no data shows up in the permanent table. My connection opens perfectly and the ...Show All
