• Smart Device Development Serial Port

  Hi all, I'm trying to write an application for my Pocket PC. The only thing I need to do, for the time being, is to read data from a Bluetooth GPS connected on COM7 of my Pocket PC (Dell Axim X50V). I've got some experience in C# programming (mostly for Microcontrollers) but I know very little about Visual C#. Looking at some samples in this forum I've managed to create an application that reads data from the Serial Port every time I press a button. It can also send data. What I haven't been able to do is to figure out how to use the DataReceived event. I just cannot make the event to trigger. I would like to use it so I only read data when it is actually received. Bellow you can find the code I'm using. Could anyone tell me wh ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. vector2 and tecture2d arrays

  I've been trying to make arrays with vector2 and tecture2d but i just cant figure it out can someone please help me out and show me how its done. I'm assuming that you want two seperate arrays, one for vector2 values and one for texture2d values. This can most easily be accomplished with the following: Vector2[] myVector2Array = new Vector2[myMaxArraySize]; Texture2D[] myTexture2DArray = new Texture2D[myMaxArraySizeTwo]; myVector2Array and myTexture2DArray are the identifiers while myMaxArraySize and myMaxArraySizeTwo are the number of values that the arrays can hold. These are zero-based (0 is the first array index while myMaxArraySize-1 is the last array index). You would assign myTexture2D ...Show All

• Smart Device Development VS2003 to VS2005 conversion

  I'm attempting to upgrade an application developed using VS 2003 for a device to VS 2005. When I open the application in VS2005 the conversion wizard runs and informs me that the conversion was OK. However on opening the forms the desigh and layout has been lost, the forms also have many additional properties, those of standard windows forms. Also in the project menu there's no indication that its a mobile device application. I tried starting a new project in VS2005 and importing the forms. This did n't work either. Its been suggested that deleting the .resx file associated with the form is the solution but I have found this to be only a partial solution as any data stored in the .resx file such as embedded images is lost.

  Hi, I am new to this forum so please condone any errors or poor protocol on my part. I am appraising visual studio 2005 Team Suite to see how we can use it to configure various roles.

Of course the alternative is to have VS2005 Team suite installed on the developers host workstations. T ...Show All

• Visual C# from dataTable to database

  hi! is it possible to do a select command on a dataTable after selecting can i insert it into a database if it is, how could this be done The best way I've found to do this so far is with a loop, a compound key in the database, and two stored procs. In my application I have to store a list of loan accounts for each of our clients, who are applying for loans through us. I have a stored proc I use to send the data in. I have to call this proc once for each row in my DataGrid. Here's the stored proc: create proc dbo.store_cust_equity @row_id int = null, @loan_num int = null, @holder_name varchar(100) = null, @amount money = null as if (@row_id = 0) begin --all rows are sent in by the ap ...Show All

• Visual Studio Team System Code Analysis has dissapear from automatic build in release mode

  When I have changed the compilation mode from debug to release, Code analysis don't apply to automatic build process. it's correct or musn't  happen this. Thank you. Regards. Separate project settings control whether FxCop rules run or not in the various configurations, so ... Set you Configuration Manager into 'Release' mode ... On the Code Analysis tab of the project check that code analysis is enabled and that the rules you want to run are selected. There is also a project setting which controls whether the pdb file is generated or not. (As I understand it FxCop relies on the pdb file in order to 'look' at your code.) When you switch to 'Release' mode the pdb file may n ...Show All
