• Visual C++ Negtive zero valid?

  Hello, I hope I am in correct forum. I am testing Visual Studio 8 RC1, and found a negative zero. Here is a C example: {    double val = 0.0;    val = -val;    printf("%g\n", val); } Output is: -0 The result is "0" with .net 2003 version. Is this a expected behavior If this is expected, could somebody point me to the documents describing new double behaviors.

• Visual FoxPro Sequential Transaction Number

  I'm working on a form that needs to have a sequential transaction number. I have a Database/Table (named Trans) in place that has a single record that holds the next transaction number. I'm not sure what the best way is to have the next transaction number appear in a field on my form. Right now I have a field named T_TRANSNUM that has it's data property set to w_trans.t_transnum. t_transnum is the name of the database field where I want the transaction number stored when the form is saved. In the INIT method of T_TRANSNUM I have the following: STORE 0 TO T_VALUE SELECT TRANS GOTO 1 STORE trans.trans_num to T_VALUE REPLACE trans.trans_num with T_VALUE + 1 this.value = T_value What is happening is that the value is displayed in the form, but ...Show All

• .NET Development C# - reading and writing memory for game trainer

  I'm interested in creating a small trainer for a single player game I made and want to know how to read/write memory with C# given a specific memory address. I found the memory addresses which hold the score (int '004F19EC') and player x position (float '01150630') and want to use them to produce variables in C# to track them and manipulate them. I couldn't find much info on how to do this. It seems I use the Marshal class but I'm having trouble figuring it out. If someone could show a sample of how this is done, I'd appreciate it. You need to get an IntPtr (pointer) to that unmanaged memory structure and use the static methods on the System.Runtime.InteropServices.Marshal class (eg. Marshal.R ...Show All

• Visual Studio Generating docs using Sandcastle (CTP) from un-managed C++

  Hi all. This has probably been asked before but...... Is Sandcastle able to or will be able to produce docs from un-managed code I've generated an XML comments file from my C++ source, but MrefBuilder can't do anything with it because my code doesn't use any managed assemblies. Running MrefBuilder on this comments file yields a "0 assemblies loaded...etc" message. This results in an empty reflection file and a wasted chm . Would creating my own .org file, based on the contents of the C++ comments file then enable Sandcastle to create the docs Thanks for you help.

• Windows Forms Creating”alert” when new file arrives

  Hello! I hope this is the proper forum for this. Every day a computer sends out new files to a certain folder in my computer. I am to check these files when they arrive, ASAP. However they come within a one hour window. This means that I have to check my folder every five minutes during the waiting time if I want to be able to check the files as they arrive. Therefore I would like to make some form of “alert” that notifies me when new files arrive in my folder, preferably but necessarily using audio. Is this possible If so how can you do it Any help very much appreciated! Thanks a lot in advance! I know I can minimize the window showing the folder and just have it at the corner of my screen but that is not very convenient as I ...Show All
