Thanks a lot for your help! That pretty much did the trick, I made a few slight modifications but it's following your idea. Thanks again!

thank you for the quick reply, unfortunately I have to use the language C. It can not be C++ or any other language.Leave a comment:

How do you create a table with variables from multiple structs?
Hi, I would like to create an array of struct variables inside a table to avoid using many if/else and/or switch/case statements. I have attached a simple example of what I am trying to do, it doesn't work. For the table "sTablePtr" I see different values than what I set, when I dereference it with a "&" it just shows me the addresses of the variables. However at the end, when I do print out the values, by just using the structs... -
Found answer - less optimal
I found the answer if anyone runs into this problem. Instead of 300 if else statements to compare the checkbox names to strings, i found this to be a better method although not as efficient as I would hope.
I saved colums of checkboxes to a checkbox array. Then I would check each checkbox name with the string I read from the file. If there is a match, then check the checkbox and return so...Leave a comment:

Oh I forgot to metion,
I know I can do it with an if condition such as. The only problem with this approach is that I have many checkboxes, so I am trying to avoid this method.
thanks again
...Code:if(lines[i]->CompareTo("checkBox1") == 0) { checkBox1->checked = true; } else if(lines[i]->CompareTo("checkBox2") == 0) {Leave a comment:

Copy String^ to CheckBox^
Hello,
I have written my code in Visual C++ using .NET Framework. I have several checkboxes on my GUI and I would like to give the user the option of saving the current state of the checkboxes. I took care of the save file, now the loading of the file is where I have my problem. The checkbox names are saved in the file, when the user loads this file back into the GUI, I read the checkbox names line by line and I am suppose to check... -
I found out what the problem was, when the timer started, the file was already closed because of the fclose statements at the bottom of findPacketHeade r. So I rearranged the code to something similar to this. Thanks for replying, I appreciate the inputs.
...Code:void findPacketHeaders(char *inputFile, char *outputFile) { pktHeader.packetSyncPattern = 0xEB25; /* Open file */Leave a comment:

Well, I tried printing what fgetc outputs which is -1 all the time or the hex representation is FFFFFFFF. It seems like the fgetc isn't working correctly inside the timer function.Leave a comment:

How to read a file in a timer function in Visual C++ using .NET
How can you read a file in a timer function? I am currently using a do while statement to read a file which works fine. The implementation is in C but I've added the code to a C++ .NET framework GUI app. This is the implementation that works:
...Code:void findPacketHeaders(char *inputFile, char *outputFile) { /* Open file */ fpInput = fopen(inputFile, "rb"); fpOutput = fopen(outputFile, "w"); -
Thanks Banfa for the information, I looked into it. This is the solution I found with help.
This is the final version, I actually needed one specific cell (column index 0) from the row that was being deleted, so hence this code works great.

Thank you very much, worked like a charm. This is the final version, I actually needed one specific cell (column index 0) from the row that was being deleted, so hence this code works great.

Help with DataGrid and MemberwiseClone() Visual C++ using .NET
I am currently using Visual Studio 2008 Pro edition programming a windows form application using Visual C++.
I am using datagrids, the user can populate fields with data. I am not using datasets because the information doesn't have to remain once the app has closed. When the user selects a row and deletes it with the "Delete" key on the keyboard, I want to trigger an event. I got it to this point but now I am having a problem... -

KevinADC you were right, I ran the perl application from the terminal and <STDIN> pauses for the user to input something. So it's the other script that's calling this perl application that's causing <STDIN> not to operate correctly.
Again, thanks for the help guys!Leave a comment:

Yes, I think you're right KevinADC. It somehow doesn't have access to the terminal, its just that since this perl application displays the contents on the terminal, I thought it would also prompt the user. I will call this perl application straight from the terminal to see if <STDIN> is working. Once I find that in this case it does work, then that confirms what you are saying.
Jeff, I understand what you are saying. My reasoning...Leave a comment:

I just tried that and it still doesn't seem to work. It doesn't prompt the user, instead it gives these errors:
use of unitialized value in chomp at line 515.
use of unitialized value in numeric eq (==) at line 519
use of unitialized value in numeric eq (==) at line 519
use of unitialized value in numeric eq (==) at line 519
line 515 contains chomp ($result = <STDIN>);

The program itself is not a GUI. This perl application is called from some other script and the perl application displays the results in the terminal. I just want it to ask the user a question in the terminal and depending on the choice the user selects, it takes the a specific route to find an alternative. This is run on Solaris 8 OS. The script itself with slight modifications works find on a windows xp operating system using the command prompt....Leave a comment:

I'm not sure if you specifically need the split function or not. I usually use the index() and rindex() function to seperate the directory paths from each other. For example: if you want to split c:\program files\software\ specific. And you wanted to split "specific" from the the rest of the directory path. I would do the following:
...Code:#you want to add 1 because you want to skip "\" $index_num

Read from terminal using Perl
I would like to know how to prompt the user for an input on the terminal. I have a print statement which asks for 3 choices and use <STDIN> to prompt the user for an input. This code works perfectly with DOS but I need it to work on the terminal. I don't know how to read from terminal. I looked up some shell scripts and it says read CMD but that command doesn't work in Perl.
...Code:print "Choose a means of transportation:\n\n";

Thanks a lot for the solution, I looked into it when you gave me the recommendation for the regex. This is the solution I came up with. I strip all the leading whitespaces and check if it's a comment or not. That's how I know it's a line of code. There is one flaw if the comment is before the line of code (/* */ code;) But that's a case that I'm not looking for.
...Code:s/^\s+//; #strip leading whitespace if(/^[^\/*]/)
