You need to convert it to an int before you can add them. Use this method:
<br />
int x = Convert.ToInt32(
int y = Convert.ToInt32(

int x;
int y;
private void btnAdd_Click(object sender, System.EventArgs e)
{
int x = Convert.ToInt32.txtFirstNum;
int y = Convert.ToInt32.txtSecondNum;
x + y;
}
It doesn't recoginze the ToInt32! Is this supposed to be my answer label name?

Can't you at least copy/paste correctly????

Needs to assign the result to something in order for you to use it. e.g.
int result = x + y; Then you can take the result and assign it to the Text property of your Label. (Remember to convert it to a string when you do that)
Does this help?

He is referring to the fact that you coded:
Convert.ToInt32.txtFirstNum; When the example clearly used brackets and specified you needed to pass in a string.
Convert.ToInt32(txtFirstNum.Text);

Just need to make a few changes:
<br />
private void btnAdd_Click(object sender, System.EventArgs e)<br />
{<br />
int x = Convert.ToInt32(txtFirstNum.Text);<br />
int y = Convert.ToInt32(txtSecondNum.Text);<br />
x + y;<br />
}
That should fix it

Ohh lol oops.
private void btnAdd_Click(object sender, System.EventArgs e)<br />
{<br />
<br />
int x = Convert.ToInt32(txtFirstNum.Text);<br />
int y = Convert.ToInt32(txtSecondNum.Text);<br />
x + y;<br />
<br />
}
Sorry bout that.

Sounds just like project 5 in the Basic Programming course at St Louis Community college.
Good luck.

Hi all,
does anyone have any idea about using the microsoft speech api in a c# application. I've got the basics down but there's limited to no documentation available. MSDN only seem to documentation, examples, etc for C++. The problem is that some of the classes etc are either not available or different in some way that those available in c#.
I'm particularly interested in changing voices, pitch, rate, volume, etc.
Thanks

Does anyone know anything about Microsoft's plans for Source Safe? Have they just lost interest in providing version configuration management packages? Someonce mentioned 2007 to me?
I am currently using the old Visual Studio Source Safe. Does anybody know of any plugins or anyway to improve the differ?
Cheers
AJ

SourceSafe 2007 was released with the latest version of Visual Studio. It has some minor enhancements and fixes and is still adequate for a very small organization. It is supposed to have a remote, non-file system based, access ability, but I never got around to testing it.
MS also has what they call Team System, which is a full blown configuration management and bug tracking system. We evaluated it and found that it was very expensive, difficult to set up and extremely complicated to customize. (Besides, it's a 1.0 release and Microsoft, especially, is known for not getting it right until version 3.0.)
Anyone who thinks he has a better idea of what's good for people than people do is a swine.

I've implemented a word template into my purchase order app. When I open the template passing the merge info, everyhting works fine. However when I exit my app and I open task manager winword is still open even though I doing a close on the app and calling the garbage collector.
Is there something else that I need to do to close word correctly? Do I need to make the class that is handling opening word a member of IDisposable?
Thanks

Did you call Close on the Word Application object? Or did you call Quit on it before you disposed it?

First I open the doc:
<br />
if (File.Exists(TemplatePath + "\\PO.dot"))<br />
{<br />
private object oMissing = System.Reflection.Missing.Value;<br />
private Word.ApplicationClass oWord = new Word.ApplicationClass(); <br />
private Word.Documents oDocs; <br />
private Word._Document oDoc;<br />
<br />
try<br />
{<br />
File.Copy(TemplatePath + "\\PO.dot", SaveToPath + "\\PO" + PONumber + ".doc");<br />
oWord.Visible = true;<br />
oWord.Activate();<br />
object oFile = SaveToPath + "\\PO" + PONumber + ".doc";<br />
oDocs = oWord.Documents;<br />
bPOCreated = true;<br />
try<br />
{<br />
oDoc = oDocs.Open(ref oFile, ref oMissing,<br />
ref oMissing, ref oMissing, ref oMissing, ref oMissing,<br />
ref oMissing, ref oMissing, ref oMissing, ref oMissing,<br />
ref oMissing, ref oMissing, ref oMissing, ref oMissing,<br />
ref oMissing, ref oMissing);<br />
}<br />
catch(Exception err)<br />
{<br />
oDoc = oDocs.OpenOld(ref oFile, ref oMissing,<br />
ref oMissing, ref oMissing, ref oMissing, ref oMissing,<br />
ref oMissing, ref oMissing, ref oMissing, ref oMissing);<br />
}<br />
<br />
Then my close:
<br />
try{<br />
oDoc.Close(ref oMissing, ref oMissing, ref oMissing);<br />
System.Runtime.InteropServices.Marshal.ReleaseComObject (oDoc);<br />
oDoc = null;<br />
System.Runtime.InteropServices.Marshal.ReleaseComObject (oDocs);<br />
oDocs = null;<br />
oWord.Quit(ref oMissing, ref oMissing, ref oMissing);<br />
System.Runtime.InteropServices.Marshal.ReleaseComObject (oWord);<br />
oWord = null;<br />
bPOCreated = false;<br />
GC.Collect();<br />
Close();<br />
}<br />
catch(Exception err)<br />
{<br />
GC.Collect();<br />
}<br />
<br />

is there a way that i can get the serial key of an installed application using a c#...
example is i have installed a macromedia dreamweaver which is a licensed one which i bought
and i want to get and display the key of my macromedia dreamweaver in my c# window form...
anyone can help me?? or guide me??
thank you very much!!

Probably not. Most applications won't save the key itself anywhere you get easily find or get at. If stored, it'll usually be encrypted, but every application is different.

I tried to find an article on how to manage IIS (creating/deleting web sites and the like). Anybody has a pointer to some useful information on how to do this?

My application will be running on a slow PIII-400 machine. And the application needs to display a lot of pictures.
At a point i need to bring up a dialog, covering the pictures. When the dialog hides, the covered form cannot refresh fast enough so that it looks very choppy.
This program is gonna be used in a restaruant, it cannot give impression that the program suk, is that any way to make sure the background has been drawn, before the foreground(the dialog) hides?

Not really. For such a slow machine, you're probably going to have to back-off on the use of background images. This is especially true if you're using images larger than they need to be and scaling them down to fit inside the form and using a lower end video card.
Keep in mind that your app is going to have to have it's own minimum system requirements. You can't just put something together and get good performance on one machine and expect that same performance on lower end hardware.
There's a bunch of optimzation techniques, but what to do is very dependant on your code and form design.
Scale images down to the size you need for the form. For example, don't use a 1280x1024 image on a form that's only 320x200. You'll waste too much time loading all the extra data you're never going to see. Along the same line, if you can get away with a 256 color image, instead of 24+ bit images, do it! The less you have to load, the better.
Don't use an exessive number of controls on a form. Controls are very expensive to create and place dynamically. Also, calling all the Paint methods for those controls takes a while too. The less you have to paint, the better!
... There's lots of things you can do, but what you do depends heavily on your code, and more importantly, your design.
You can start by skimming through Improving .NET Application Performance and Scalability[^].
