• Smart Device Development Serial Ports and PPC

  Hi, I am currently porting a simple piece of win32 code to PPC 2003 using VS2005. I have trouble openening up a serial comport. In the code I am using on PC, I am using CreateFile for opening COM ports. Is it not possible to use that on a PPC device . I keep getting an invalid handle back.

Being a newbie that is abit much to start looking into just to get a simple comport to work... Could anyone please give me some hints on this one Many thanks in advance, ...Show All

  Hi all, in my application, I have a CSliderCtrl and also one timer. at the timer event, I read the values from an instrument, and refresh the interface, also the CSliderCtrl.

• Game Technologies: DirectX, XNA, XACT, etc. Scene data

  Hi, Does anyone have any tips on how to run through scene-data. I've noticed that the data has to be 'tree-like' because you have objects, groups of objects and groups within groups. For example, if I have the text - 'This' in my 3d scene, all the letter objects are in a group (with a common origin), and the 2 parts that make the 'i' are in a group that is within the group. I had a good idea of writing a function which runs through the data, and when it comes across a group of objects - it calls itself . This works well with tree-like data. However, I'm not sure if the processing that goes on when a dynamic function ...Show All

• SQL Server Optimizing LIKE OR Selects

  I'm having problems optimizing a sql select statement that uses a LIKE statement coupled with an OR clause. For simplicity sake, I'll demonstrate this with a scaled down example: table Company, fields CompanyID, CompanyName table Address, fields AddressID, AddressName table CompanyAddressAssoc, fields AssocID, CompanyID, AddressID CompanyAddressAssoc is the many-to-many associative table for Company and Address. A search query is required that, given a search string ( i.e. 'TEST' ), return all Company -> Address records where either the CompanyName or AddressName starts with the parameter: Select c.CompanyID, c.Comp ...Show All

What do I do if I want to mask a key or several keys for an entire program Would I have to put a mask everywhere or is there an easier way to do this. If you must know what this is for, then here is the skinny. My friend and I are what you would call pranksters.
