Yes you can do that, but it will result in the 'stupid user' complaining about the execute button not being active. At least the way it's handled here offers the opportunity to explain why this won't work, and what is expected. Granted, it could be expressed ... differently ![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

I just use a message box that says "Too late for sorry, earthling!" It should NEVER be seen by anyone but me, and so far <crossing wings> I have yet to hear about it

Perhaps because such a message screams to the user that you don't want to hear about it if it ever does happen.
At least add a unique guru meditation number or something to the message. That'll turn it into a whimisical way to deliver an obscure error. Might someday keep your management from loosing face to some customer with clout who happens to get that message.
We can program with only 1's, but if all you've got are zeros, you've got nothing.

Yes, I too once coded an error message under a condition that at that point I assumed was a foregone conclusion. It said sth along the lines of. "you should never see this error message. If you do, please contact <my name>"
Of course, that impossible condition did hit eventually, and I got a call from our customer.. Thankfully the software was still under testing at that point so it wasn't some clueless user, but a rather exhilarated tester...

precisely <chuckle> - but people who use software that6 still contains that as an error message know me well enough that calling me is the first thing they would do anyway

Agreed. Keep thinking your user is "stupid" and pretty soon you won't have any.

What's the name of the validator app?
|
|
|
|
|
I called it "Rude XSD validator".
It was something I threw together in a hurry. The software we develop is serviced/administered by another company. We had a situation in which we needed to know if XML files provided by a third party were in accordance to a given XSD. The administrators were unable to figure it out and asked me to provide them with a tool...
So I quickly threw together a WinForms GUI in which one can load one XSD, easily choose one or more files, and validate them all.
In other words, a few people I knew a little and collaborated with would be my users. We have an informal tone, and nobody complained of anything.

There is a great tool for working with images called "ImgBurn", it has more coded insults than any other application I've ever used.
It's more condescending than anything, like, hey, I've noticed you're doing it wrong, would you like me to do it right? (Yes, No)
It's also very good at it's job, and has saved me a TON of wasted disc, I highly recommend it.

I looked those up on Google, and found that those are quotes from movies. They can be turned off in the options dialog. I never noticed them before, and I use ImgBurn quite a bit.

We can strip leading and trailing spaces from a string….
int len = strlen((LPSTR)wName);
while( *((LPSTR)wName + len - 1) == ' ')
{
*((LPSTR)wName + len - 1) = '\0';
len = strlen((LPSTR)wName);
}
firstNonSpace=((LPSTR)wName);
while(*firstNonSpace != '\0' && isspace(*firstNonSpace))
{
++firstNonSpace;
}
len = strlen(firstNonSpace)+1;
strcpy((LPSTR)wName, firstNonSpace);
Or just call…

You should probably add your context, as PathRemoveBlanks is a shell utility function, while most people here use dotnet where String.Trim would suffice.

1. This code was COPIED to 3 different places - they didn't bother to make a function out of all of it. That is probably the worst error, because now if this 'new' code has bugs, you have to modify three places instead of one.
2. It 'excessively' calculates the length of the string. I think I am being kind here when I say that.
3. 'Familiarity' was my joke - there is already a function in Windows to do this.

Or you can create a function with this code and replace the code in the other 3 (and modify just one).

And just as excessively casts wName to LPSTR.

Not sure if you are joking, or looking for a serious answer.
The code you posted makes WAY too many passes through the source string. If you're looking for maximum performance, you can get this down to just a single pass thusly:
LPSTR* nxt = wName;
while(*nxt && isspace(*nxt))
nxt++;
if (!*np) {
wName = '\0';
return wName;
}
LPSTR* start = nxt;
LPSTR* last_no_ws = nxt;
while(*nxt) {
if (!isspace(*nxt))
last_no_ws = nxt;
nxt++;
}
int len = (last_no_ws - start) + 1;
memmove(wName, start, len);
wName[len] = '\0';
return wName;
You could even save the 'memove' at the end by just modifying the wName string in place (add null after last_no_ws), then return the reference to 'start'.

This is great. I was just posting the orginal code because of the three reasons I listed. 1. Should be a function - REGARDLESS. 2 - It's inefficient on multiple levels. 3. MS already has the 'tried and true' function to call anyways.
I like to see that others do not consider what I posted to be optimal in ANY case, so that is comforting

Changes:
1. Clear defined end of first loop cutting trailing spaces
2. No undefined behavior of strcpy with overlapping memory areas
3. No unnecessary strlen calls
4. Unified way to test for whitespaces via isspace
5. No warnings because of signed/unsigned conflicts (int <-> unsigned int strlen(...))
LPSTR myStrTrim(LPSTR pszString)
{
LPSTR pszLastChar = pszString + strlen(pszString) - 1;
while (pszLastChar >= pszString && isspace(*pszLastChar))
*pszLastChar-- = '\0';
LPSTR pszFirstChar = pszString;
while(pszFirstChar < pszLastChar && isspace(*pszFirstChar))
++pszFirstChar;
memmove(pszString, pszFirstChar, pszLastChar-pszFirstChar+1);
return pszString;
}

One of the best languages for string manipulation is PowerBasic. You can use it to write 32 bit DLL's callable from other languages.
To trim leading spaces: LTRIM$(AnyStringVar)
To trim any character from left: LTRIM$(AnyStringVar, SomeCharacter)
To trim any of multiple characters from left: LTRIM$(AnyStringVar, ANY SomeCharacters)
To trim trailing edge spaces: RTRIM$(AnyStringVar)
To trim any trailing character: RTRIM$(AnyStringVar,SomeCharacter)
To trim any of multiple trailing characters: RTRIM$(AnyStringVar, ANY SomeCharacters)
Trim both leading and trailing spaces: TRIM$(AnyStringVar)
Trim any character leading or trailing: TRIM$(AnyStringVar, SomeCharacter)
Trim any of multiple characters leading and trailing: TRIM$(AnyStringvar, ANY SomeCharacters)
PowerBasic supports pointers too !

[Edit]
I know it is not a crime, but I had to fight against inconsistent variable names and bit of spaghetti code.
But the most important thing is: This piece of code has to parse a huge amount of data (up to 500000 rows with parameters and so on) so you remember if it needs 50 or 4 seconds to parse the parameter values (overall time).
[Edit end]
I found this piece of code in a project which I had to expand. Notice the guy who wrote the code was at the end of his apprenticeship with already 4 years experience in coding. 
public void LogFileBreakDown(string channel, string channelnumber)
{
int channelnumber = 0;
try
{
channelnumber = Int32.Parse(channelnumber);
}
catch(Exception ex)
{
channelnumber = 0;
}
return;
}
I replaced Parse with TryParse -> and the log file was loading about 30 times faster then before.
