Okay I have a question
const int MAX = 30;<br />
char fileName[MAX];<br />
char name[MAX];<br />
cout << "enter the file name: " << endl;<br />
cin >> name;<br />
fileName = name + ".txt";
My question is when I try and compile this it give me this error.
invalid operands of types `char[30]' and `const char[5]' to binary `operator+'
What is wrong with this code. I was told it is correct however I can not get it to compile.
led mike thanks for the great help on the last problem.

You can't concatenate char arrays like that in C/C++.
Here's one way you could build fileName:
strcpy(fileName, name);
strcat(fileName, ".txt");

Thanks Mark. I was told wrong. I thank you for clearing this up for me.
Now it works and I understand.
Thank you again.

I cannot run my application .exe on other pc. Error message like this "The application has failed to start because the application configuration is incorrect. Reinstall the application may fix the problem." But I can open the application on my own pc which I built and debugged the application. What may be the problem?

The problem very likely is that you have not fulfilled your responsibility as a developer and read the MSDN Documentation on Deployment for the tools you used in constructing your application. Did I get it right?

I am still a student. Every semester I change to use different software depend on the project. Frankily speaking, this is the first time I use visual studio. I do admit that I have skipped the MSDN Documentation due to the time constraint. I just did the coding, built and debugged it to come out the .exe file then assumed that it can be run on same window platform on other machine. Did my answer statisfy you?

Yes, I was right. Now let's recap. You don't have time to read the deployment documentation but you do have time to read the same information if someone types it into a forum message? I suggest you take a course in Logic while at the University, it tends to come in handy while developing software.

Also you will find that making assumptions doesn't come in very handy while developing software.

Ya, I will have time to read it because that is the solution. Let see a scenario: if you are going to have test 2 days later and still have ten chapters not yet finish study, even worse that you no pay attention during lecture, what will you do? As for me, i will hope that lecturer can give some tips or go through past year paper question to get some hints. That is what I am doing.
When I started this thread, I didn't have any clue about the problem. If solution is too long to write in forum, I would just expected that someone give me a direction, e.g, read the MSDN deployment documents. Now I will read it, thats all. One more thing, in my field of study, assumption is important and a course of logic not exist in my university.

Hi,
Please post the code snippet and state in which line are you getting the compile error.

(Hopefully this is the right forum - This is all done in VC++.NET)
Sprinkled Throughout the various project I have are some where, if the design mode window is part of startup, it takes a rather long time for the project to be loaded. Similarly, if already opened, opening the design-mode window take a rather long time. I believe I know why it's happening, but I don't know how to stop it - and it can be very annoying.
Why I know:
1) Projects with database's attached (::SqlClient) are the worst offender - but not all of them.
2) A digital clock custom control I made, when put into a project, was actually ticking merrily away in the design mode window
I conclude that the horrid delay may be establishing (and timing out) of dBase connections.
Does anyone know how to disable this 'live' state of a project that, in my philosophy at least, should not be running?
For now, it's a catch-22: I can re-arrange the code and the items aren't intialized at this point - but that also means they're not on the designer window and that sort of defeats the whole purpose - which is having an open designer window.
Thanks, in advance,
Balboos

The designer interfaces include the ability to know during initialization if it is a designer instance. You can use that information to avoid doing any processing that you don't want the control to do in designer mode.

Now All I Have To Do Is Hunt This Down this Knowledge - from you comment, I gather it is not a setting.
Thanks for a direction.

If by that you mean read the documentation then yes. If someone has told you can become an accomplished software developer without reading the documentation they told you wrong, don't believe them.

I know the intent of your comment, so I'll take it as well-meaning. My statement was rhetorical.

As for development, I bootstrapped my way through all the coding method - learning assembler before C, for example. All of it from books, the occasional system help file, and copious sweat.
But -
MS loves to jerk around with users - moving things around, changing them, etc. There may well have been a setting to fix the problem somewhere (but certainly not in MS Help - aka "Idiots Guide To Chasing Their Own Tail").
There is another concept - and when used with appropriate discreation - equally valuable to that of looking-it-up: putting ones ego aside, admitting ignorance, and asking.
Learning to say "I don't know".
So - indeed - you're right in discouraging moochers and general brain-sucking by the lazy. But, just the same, we are (or should be) a gestalt community.

Yeah I gave up on that years ago. I always use Google to search MSDN by just putting MSDN as the first key word.
I don't remember the specifics so I couldn't tell you but it's part of the Designer library that contains what I referred to. So like System.Drawing.Design but I seem to remember there might be another namespace also containing Designer classes.
Anyway, I know it's there but I can't give you the specific location.

Thanks for a nudge in the rigth direction.
All those namespaces - it's easy to get distracted. Actually, that some of the fun of it: like looking up a word in a (paper) dictionary and then browsing a bit at the words around it. One of the losses of electronic equivalents (at least for now).
Today's my half-day: I can give the design namespace(s) a good spin. I blew much of yesterday addressing a minor failing in the automatic refactoring (if that's the correct term, snicker) when a class is renamed: to wit, I created a Windows.Forms project (as an executable) and renamed Form1 to a relevant name.* It sadly does not fix the references to the .resources files, manifesting itself as a runtime crash. Finally found the right option for changing the reference. Maybe VS10 will fix this.
If I get this to fix the design-time execution, I'll let you know the specifics. I can't be the only one suffering from this.
* the .exe can be referenced like a dll, but who want to work with namespace::Form1, anothernamespace::Form1, etc. Why do it this way, instead of a form class directly? much more rapid development. I can convert it to a real .dll if/when I have to.

Can anyone tell me how to find which specific processes are running on opened TCP ports??
As far as I sacnned the MSDN documentation, the information is found in GetExtendedTcpTable
and we have to import iphlpapi.dll for this..
Here is the snippet of my code:
class ProcessClass<br />
{<br />
public:<br />
[DllImport("iphlpapi.dll")]<br />
DWORD GetExtendedTcpTable(PVOID tcpTable, PDWORD tcpTableLength, BOOL sort, ULONG ipVersion, TCP_TABLE_CLASS tcpTableType, ULONG reserved);<br />
MIB_TCPROW_OWNER_PID tcpTable[2000];<br />
<br />
void GetProcesses();<br />
};<br />
<br />
void ProcessClass ::GetProcesses()<br />
{<br />
DWORD size = 2000;<br />
GetExtendedTcpTable(&tcpTable, &size, FALSE, AF_INET, TCP_TABLE_OWNER_PID_ALL, 0); <br />
}
But the problem is that I get an empty 'tcpTable'..
How to get the process ID's??

Why are you using DllImport when you are developing in C++?
