I should have figured that, just checking, I was going to split it, then check for a zero length or 1 length string.

Need you help, thanks!

Look in the documentation at the System.Convert class. This object has all sorts of functions to convert. There is an overload in there that will convert long structure data to char structure data assuming that is really what you wish (keep in mind char in the CLR is 16 bit, unicode character data type and long is 64 bit integer).

and save yourself some cash.
1. This forum is for C#, not C.
2. Pick up a book and read it, get glasses so you see the differnce between C & C#. You will likely see a similar example of what is required of you.
3. No, we dont do your homework, thats your job, why are you taking this course anyways, if you dont want to learn?

While I agree with leppie to an extent, I still hate to not help somebody coming in here with questions...
I haven't used c in a while, so I might be a little off, but you should get the idea from this (you'll probably need to check the include libraries, not sure where IsAlpha( char ) lives)
you've already declared your input, which you called imput, with a length of 100...so let's just go from there.
char imput[100]="interesting, this class of robotics";
int iLowerBound, iUpperBound;
for ( int x = 0; x < 100; x++ )
{
if (isalpha( imput[x] ))
{
iLowerBound = x;
while (x < 100 and isalpha(imput[x]))
x++;
iUpperBound = x-1;
for ( int y = iUpperBound; y >= iLowerBound; y-- )
printf("%c",imput[y]);
}
printf("%c",imput[x]);
}
I didn't test this, and really have no clue if it works...I just wrote it off the top of my head in about 5 minutes. Assuming it does work, this should be about all you need. Hope it helps...

what is the code I would use to, say, run a file called "hello.txt" in c:\documents\hello.txt
if I get this, I can figure out how to open the other files I need to
|

|

I'm a bit confused  Do you want to run or open files?
In first case take a look at the Process and ProcessStartInfo classes and in second case look at the System.IO namespace.
If that doesn't help, please be a bit more specific.

sorry, I need to be able to simply execute a file. also, while your reading this, how do I uninstall a program that is registered in the control panel, but doesn't come with an uninstaller. I mean, is there a way to "open" the control panel and remove the program with that through code. How would I go about doing that?
Danke Schon.

"sorry, I need to be able to simply execute a file":
As I stated in my previous posting take a look at the Process and ProcessStartInfo classes. The appropriate MSDN topics provide some examples, so you should have no problems with that. Otherwise let me know what concretely doesn't work.
"is there a way to "open" the control panel and remove the program with that through code":
As far as I know the list of installed programs that is accessible through the control panel is based on information inside the registry. So to "uninstall" the program you'll have to remove the right registry entries, which is possible in .NET (RegistryKey and Registry classes). But please don't take this for granted as havn't much experience in this field and maybe start a new thread with this particular problem.

I am a student of a c programming class in Texas. Our teacher is one that does not assist all that much but chooses to leave us to our own devices in programming his projects. That said, i am asking for any assistance that may be given in helping me write a program that
"can reverse the characters in a word, but leave it in its original position in the sentence"
Heres what ive coded so far:
#include <stdio.h>
#include <stdlib.h>
int main(int argc, char *argv[])
{
char imput[100]=" interesting, this class of robotics";
char list1[30][50];
char databank[50];
int i=0;
int j=0;
int k=0;
while(j<30){
j++;
while(k<50){
k++;
list1[j][k]=0;}
}
while(imput[i] !=0){
if (imput[i]=32){
j++;
k=0;
i++;}
else{
list1[j][k]=imput[i];
k++;
i++;}
}
for (k=0;k<60;k++){
for (j=0;j<30;j++){
printf("%c",list1[j][k]);
}
}
i=0;
while(i<30){
databank[i]=0;
i++;}
for(i=0;i<60;i++){
while(list1[j][k] !=0){
databank[i]=list1[j][k];
i++;
k++;
if(list1[j][k]=32){j++;}
}}
i=0;
while(i !=20){
printf("%c\n",databank[i]);
i++;}
// j--;
// k=0;
// while(j>-1){
// list1[j][k]=databank[j];
/// j--;
// k++;}
// }
// for (k=0;k<60;k++){
// for (j=0;j<30;j++){
// printf("%c",list1[j][k]);
// }
// }
system("PAUSE");
return 0;
}
Our next project is to sort a list of integers in ascending order, ill happily accept any help offered on either of these projects.
Thanks
Bill

I don't think it's that easy. How do you know the color of a specific pixel? if you can read it you probably can overwrite it.
try reading this[^]

Ladies & Gentlemen
I have two issues when dealing with windows forms data binding.
1-I have created a windows form . And on it I have added tab control which has other controls .
I f I create a method to clear all controls on the form of data. Only controls on the tab that has focus are cleared of data. others remain uncleared and especially ComboBoxes.
How can I write a method to clear my form after data entry.
2-Second issue ,I have employee details. I have Banks and Each bank has branches. I want to create ComboBox that list all Banks and this should be linked to Branches ComboBox and the branches comboxBox should have its SelectedValue pointed to employee data row. That is it should make the look up table containing bank branches form employee data.
Meaning that if an employee has his account with ABC bank ,it should also specify the branch. That is I have a list of branches for each bank.
How can I implement this lookup hierarchy.

Hi
How i can retrive an resource (Bitmap for handle) from my project.Before now i handn't experince with .Net resorces
and i anticipate this in the same way like in MFC projects, but there is no resource files, and i just add my bitmap inderectly to project(Project->Add New Item->Bitmap)is it correct? .And now i want to get the bitmap ID from my code.
Where is a way to do so??
Thank.

Thank.
Oddly enough, i suppose using resorces in NET became more
simplest, but in oppositely it seems more complicated.

no not really, the only importand thing is:
ResourceManager rm = new ResourceManager("app", this.GetType().Assembly);<br />
<br />
rm.GetObject( "keyname" );<br />
rm.GetString( "keyname" );<br />
no big deal - for editing resources u can use Resourcer[^]

In .NET 2.0, it's become even easier:
Image myImage = Properties.Resources.arrow;

Hi,
is it possible to set a row fixed under the header of a column so when i scoll it's always on top too?
if tried some overrides but i don't really know where to begin? Changing things like the scrollbar values don't fix the row on the top.
Any ideas?

Hi all
I have developed a com interop application in C#, its output is .dll.
It is working fine in the workstation (win XP)
Now I wand manually (Again Manually) deploy the same DLL in windows 2003 server, the server already has .net Framework,Can any one tell me how to deplay the com interop DLL?
More over I am integrating the C# DLL with a VC++ (Version 6) Client, the client will read the CLSID from the registry and create the instance of the .net component.In this case can any one guide me that how to deploy the interop component?
Thanks

I have a custom class within my code and I place multiple instances of this class into an ArrayList. At certain points in the code I would like to check if an instance of an object already exists in the array (not really an instance as such, more an object with the same values).
Now this doesnt work, I am certain that I am expecting far to much from the .Contains() function - so if anybody has any guidance on another solution please post it up.
As an example of the "problem" :
The following code returns false
private bool TestMe()
{
testClass tc1 = new testClass("abc", "def", "ghi");
testClass tc2 = new testClass("123", "456", "789");
testClass tc3 = new testClass("xxx", "yyy", "zzz");
testClass tc4 = new testClass("abc", "def", "ghi");
ArrayList array1 = new ArrayList();
array1.Add(tc1);
array1.Add(tc2);
array1.Add(tc3);
return array1.Contains(tc4);
}
The code above uses the following class
internal class testClass
{
public string abc;
public string def;
public string ghi;
public testClass(string abc, string def, string ghi)
{
this.abc = abc;
this.def = def;
this.ghi = ghi;
}
}
But interestingly this returns true
private void TestMe2()
{
string tc1 = "abc";
string tc2 = "123";
string tc3 = "xxx";
string tc4 = "abc";
ArrayList array1 = new ArrayList();
array1.Add(tc1);
array1.Add(tc2);
array1.Add(tc3);
return array1.Contains(tc4);
}
I assume that it works with basic types but not anything custom
post.mode = postmodes.signature;
SELECT everything FROM everywhere WHERE something = something_else;
> 1 Row Returned
> 42

use this test class and it will work:
internal class testClass
{
public string abc;
public string def;
public string ghi;´
public testClass(string abc, string def, string ghi)
{
this.abc = abc;
this.def = def,
this.ghi = ghi;
}
public override bool Equals(object obj)
{
testClass t = obj as testClass;
if (t == null) return false;
return t.abc == this.abc && t.def == this.def && t.ghi == this.ghi;
}
}
