• Visual C# Running C# Commands from a parsed text file?

  Is it possible, say you have your main program, and when it initializes, it will scan this text file, looking and trying to execute all commands that are listed, like running a method inside the program, or if you put MessageBox.Show("",""); In the text file, or is there another way of doing this, I'm not going to make the program only understand commands that I put in it, through a switch statement, or if statements, I want it to directly interpret it. Checking out the built in C# Compiler, it looks like it would want me to have a seperate executable though, doesn't it Also, is this implicitly supported by the .net framework or is it with VS With a seperate Executable, I don't think ...Show All

• Visual C++ Floating point stack overflow

  My application works fine in VS2003, but in VS2005, it is producing an overflow of the floating point stack.  This seems like it must be a code generation error in the new compiler.  Has anyone else experienced this problem In the particular case I am looking at, I step through the instruction FLDZ in the disassembly window.  Instead of getting a zero in ST(0), I get 1#IND, and the SF and C1 bits are set in the x87 FPU Status Word.  The first time through this code it works OK, but this second time through, the FPU tags register shows that the stack is full before the FLDZ instruction. That document on the floating point model is excellent.  Thanks.  It turns out my problem is a code generation bug ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Realtime Drawing

  Hi there, I am new in graphics programing and I want to develop a simple applciation (like a simulator) that draws waves based on values comming (like what happen in heart beat graphs, certain values coming from ECG sensors continously make the waves on the display screen). Regards This can be done but as you are just starting out you might want to look at using GDI+. Here is a link to a good faq site on the subject. You could also use DirectX but it would take a bit of education to get you started, the best place to look at the moment is www.thezbuffer.com as the zman has a good list of tutorials that you can follow (Note www.thezbuffer.com is mainly for managed languages which include c# and vb.net, if you want to use ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Could C# be the future of gaming?

  Since XNA is using C#, and is is a more intuitive language than C++, is it possible that in the future that C# will dominate, espessially in AAA titles. Could XNA be ushering a new way of programming in the main stream For now, at least, no; C# as well as Managed DirectX still have a hurdles to get over (IMO). The language is still relatively new, developers are still learning the ins and outs and how to push applications developed in C# to the limit. In my opinion, although I love C# and swear by it, the professional community is and will be very reluctant to drop C++ for a newcomer such as C#, especially considering its lack of cross platform abilities. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Garbage Collection

  Hi. I'm not a game programmer yet but I'm a programmer. I have been learning computer graphics (opengl) at school and while I was talking to one of the professor was referring to Java as the main problem is that the garbage collection does not permit it to be real time. I know that the .net framework which I use quite often has garbage collection as well. The problem with garbage collection is that you (the programmer) does not know when it will happen. My question are 1) Is Xna going to have garbage collection and 2) if it will have garbage collection, wouldn't this make a video game slow thanks Francisco Shawn Hargreaves wrote: ]A lot of the code for Unreal Engine games is written in a scripting la ...Show All

• Visual Basic Error codes

  When I use an add command to add data to an Access dB, supposing that db doesn't exist or a connection is lost to the dB or anything atall, and my VB program returns an error to my program, rather than allowing it to crash is there an error code that gets returned that I can use to handle the program execution appropriately thanks tattoo no worries at all. Usually when you type code in Visual Studio and you access a method, a tooltip appears with info about that method, sometimes it gives you the list of exceptions that will be thrown by executing that method, so you know you need to implement the exceptions around it. Now, when an exception is thrown, it goes into the catch block. So in ...Show All

• .NET Development Reading the first half of a split record with C#

  Hi, I have a record that has a fixed length of 253 characters. The record is split into multiple sub- records each of a different length. The first sub-record has a minimum length of 125 and I need to process only this. Doing something like this : if(record. length > 124){ //process record } will work for records that have a minimum first sub-record length of 129 as subsequent sub-records will be <= 124 (253-129 = 124) and will be skipped. But in a case, where the the record is split into 126 and 127, the above code will not work as it will read both the sub-records ( and I need only the one that is 126). Can somebody tell me how I can solve this problem and read only the first sub-record . Thanks much!! ...Show All
