I'm going to start getting back "into" some coding again after a hiatus (actually it's a fairly long one, though I did briefly do some stuff for work here). I've always used Visual Studio 6 and C++/MFC. I have a new vista laptop and even after the patches, found that my shiny new VS 2005 that work bought for me doesn't always work properly when writing simple dialog apps with controls. On the whole, that's the kind of thing I would like to do a lot of, though I will try out "proper" MDI applications at some point.
My point is this - I see a lot written now about .NET and C#, am I better off looking at that and learning those from scratch, or should I just refresh and improve my knowledge with C++/MFC in particular. These won't likely be "hardcore" industrial apps, but I would like to write things that are a bit more robust at some point.
I think at work they might well get an old VS installed at some point, maybe even v6, but at home, it seems a shame that I'm a bit suspicious of VS2005 which is newer of course.
Basically, any advice would be welcome, this isn't spam or trying to get controversy or arguments, nor do I really need any cryptic replies like "use what you feel most comfortable with". I'm at a point where I really can think about where to invest a bit of time and self learning and start playing around. If someone can tell me about other IDE's or perhaps quell my fears about VS2005 in Vista (I even read that you need Vista Business - not sure which I have, but I don't have the most expensive version, nor the cheapest) then perhaps I'm Ok just carrying on with simple dialog apps in MFC for now, but am I missing the boat here, is C# and .NET taking over?

Unfortunately, all you're going to get are opinions.
Research the options and decide what's best for you!
I personally would not use VC6 anymore if you have VS 2005.
With VS 2005 and beyond you'll have many more options in one package,
include improved MFC, improved C++ compiler, C++/CLI, C#, ...
But that's just my opinion.

opinions are fine and thanks for yours. I'm sure I did install some kind of 'patch' for Vista but remember that it didn't seem to fix all my issues relating to adding control variables to controls and things like that. I've seen there is a 430 MB VS 2005 SP1 Team Update(what????) and a Vista SP1 Update at 29MB, not sure if they are both part of the same process, I'll see if I can find what it was I installed when i first got the laptop, probably summertime 2007.
cheers!

Oops I forgot about you mentioning VS2005 not working well on Vista...
It should work fine, so something (obviously) is wrong...
I would recommend installing the VS2005 SP1 for sure. Yes, it is huge - pretty much replaces most of VS haha.
Also, if running your apps from the VS debugger, try running VS as an administrator
if not doing so already (this is no longer required in VS 2008).
Cheers,

Yeah that would be wrong anyway. Languages and IDEs are tools. Not every problem is a nail therefore not every solution is a hammer. Hopefully that doesn't sound cryptic to you. While the field of software you work in may not narrow things down to a single answer it might tend to point towards a smaller list. You have not provided us with that information.

Well I thought I had provided you with that information. I'm not writing full scale projects, mainly dialog based apps for my own amusement, but with a view at some point to also writing similar tools and utilities for work. As I've not really been "in" the field for a while, now was a good time to get an update as to whether that kind of thing is better done now in the new technology or not

Well I'm not sure how to respond to that. There is a significant difference in the type of software you need to develop if your "work" is in a company that makes robotics or missile guidance systems as opposed to a company the sells books from a web site. These are types of things that might make a significant difference in language and tool choices.

I understand that, but probably if it was that serious I'd mention it The fact that it is "simple dialog apps" is a bit of a clue though, it's generally data analysis type things base on the MFC dialog app wizard - so, no, nothing fancy, though on occasion it's data that will be used in a clinical situation so accuracy is sometimes very important in terms of calculations and data flow.

Based on the information provided I see nothing there that indicates that using .NET and C# would be detrimental. The combination of the language and IDE make it probably the most Rapid RAD combination today. So since you don't appear to have any special considerations that might cause any barriers I would likely choose C# if I were in your shoes.
Also keep in mind that even if you find you have some calculation performance issues, which is unlikely, you can develop a C++/CLI assembly in mixed mode so you can do large calculations in native C++ or even assembler and provide a .NET class as the interface so it can easily be consumed by your C# project.

The auto conversion does not help.. And i have many errors.
Help...

I recommend that you post a resonable cross section of those errors or any replies you do get will just be speculation and speculation on your capabilities is probably just as likely as speculation on your problem.
Nothing is exactly what it seems but everything with seems can be unpicked.

Pick one error that happens a lot, check MSDN or google to see if it's a new "feature" of VS2008.
if it's a new "feature", you can probably define something to override it.
other than that, pick one error and fix it, go to next error and repeat.

I need help on just re-writing this function I created to something else that also functions the same for a friend of mine to use. Here is the function code:
*These are just input parameters
NoErrors is a Bool: passed by reference
amp is an int: passed by reference
string g[]: an array
string key: just a string
void Check(string g[], int& i, bool& NoErrors, string key)
{
while(g[i].length()!=4) //Checks to see if it is 4 letters
{
g[i]="";
cout << "Please enter 4 colors!" << endl << endl;
cin >> g[i];
}
NoErrors = IsStringLike(g[i], "RGBCMYrgbcmy"); //Checks for right input
// The IsStringLike is a function I also have but that does not need to be changed
// If checks to see if the string is like the characters in "RGBCMYrgbcmy"
while(NoErrors == false && g[i]!="Fred")
{
g[i]="";
cout << "Please enter appropriate colors!" << endl << endl;
cin >> g[i];
NoErrors = IsStringLike(g[i], "RGBCMYrgbcmy");
}
//Fred Cheat - allows user to display the code before the game is over
if (g[i] == "Fred")
{
cout << key << endl << endl;
g[i]="";
cin >> g[i];
while(g[i].length()!=4) //Checks to see if it is 4 letters
{
cout << "Please enter 4 colors!" << endl << endl;
cin >> g[i];
}
NoErrors = IsStringLike(g[i], "RGBCMYrgbcmy"); //Checks for right input
while(NoErrors == false && g[i]!="Fred")
{
cout << "Please enter appropriate colors!" << endl << endl;
cin >> g[i];
NoErrors = IsStringLike(g[i], "RGBCMYrgbcmy");
}
}
} // End of function
This function is an error checking function and it checks for valid input in a game I'm creating. I hope that the comments in the code are suffice for you to understand what that particular part does. I just need to somehow alter this code and make sure it still does its basic function but written different. It's a little hard to alter something and make it work the same as the initial function. Please email me if you have any questions. Thanks for your time! I hope you can help.

Rewrite it by yourself.
Follow these:
use vector instead of array.
<br />
void Check(vector<string> g, int& i,string key)<br />
{<br />
}<br />
btw, I dont understand a point here. If you already know the index, And if you are not making use of it like an offset, like i+n,i+n*2 and simply using [i], why do you send both index and the array to a separate function?
eg:
int nCheckItem = 3;
std::vector<std::string> vec_stCol;
//Assume you have 5 elements inside vec_stCol. You can make the checking function like :
<br />
if(check(vec_stCol[i],"mykey"))<br />
{<br />
. <br />
.<br />
}<br />
<br />
bool check(const string& stToBeCompared,const string& stCompareKey);<br />
<br />
use stToBecompared.Find() to check if the stToBeCompared string contains stComparekey in it.
Rest of the part, it's same, make use of find() algo.

French? RPN? Sans STL? If you wrote it, why can't you rewrite it? Please explain what the problem is.

Geez, it's a friend - just give him the working function as-is!

I used it as a image/bitmap in a memory Graphics object.
When client resizes, it should be resized too.
Now I construct a new one every time, any effecient way by GDI+?

Just use a mapping mode like MM_ISOTROPIC or MM_ANISOTROPIC.
output the bitmap in logical coordinates(window) and the device context will automagically transform it to client coordinates(viewport).
It works pretty nice assuming you set everything up correctly.
