Hallo!
What is the problem?
I have the Server and Client form here http://board.gulli.com/thread/141481...t-fhig-machen/[^]
So it works the fully code, i can open Word,Ecxel and shutdown in x sec.
f (get == "rWord")<br />
System.Diagnostics.Process.Start("winword");<br />
if (get == "rExcel")<br />
System.Diagnostics.Process.Start("excel");<br />
string[] get_Split = get.Split('~');<br />
int time = Convert.ToInt32(get_Split[1]);<br />
if (get.Contains("rshutdown"))<br />
{<br />
System.Diagnostics.Process.Start("shutdown", "-s -t " + time.ToString());<br />
}<br />
}
And so it do nothing!
string[] get_Split = get.Split('~');<br />
int time = Convert.ToInt32(get_Split[1]);<br />
if (get.Contains("rshutdown"))<br />
{<br />
System.Diagnostics.Process.Start("shutdown", "-s -t " + time.ToString());<br />
}<br />
}<br />
if (get == "rWord")<br />
System.Diagnostics.Process.Start("winword");<br />
if (get == "rExcel")<br />
System.Diagnostics.Process.Start("excel");

OK Sorry
The first code i have posted works!
And the Second is the same but the Array is in the end!This code doesn´t work!
|
|
|
|
|
are you getting any error... because in your sample the first method and the second method both are same... the only difference is the ifstatement goes last and the arrar comes first...
|
|
|
|
|
you getting a compiler error? or runtime?
what about the second '}'? is that in the wrong place? hard to tell without the opening code

Do you have an example value for "get" ?
Also System.Diagnostics.Process.Start("shutdown", "-s -t " + time.ToString()); will shut the machine down if called, not Word or Excel.

It´s difficut to explain it!
I have a Server and a Client. the Client have many Buttons for examble open Word , shutdown,...
When i use this code in the Server i can click on open Word or shutdown both works!
if (get == "rWord")<br />
System.Diagnostics.Process.Start("winword");<br />
if (get == "rExcel")<br />
System.Diagnostics.Process.Start("excel");<br />
string[] get_Split = get.Split('~');<br />
int time = Convert.ToInt32(get_Split[1]);<br />
if (get.Contains("rshutdown"))<br />
{<br />
System.Diagnostics.Process.Start("shutdown", "-s -t " + time.ToString());<br />
}<br />
}
When i use this code where the sring[] is on the front place i can´t open word! but i can shutdown the Pc in x sec!?
<br />
string[] get_Split = get.Split('~');<br />
int time = Convert.ToInt32(get_Split[1]);<br />
if (get.Contains("rshutdown"))<br />
{<br />
System.Diagnostics.Process.Start("shutdown", "-s -t " + time.ToString());<br />
}<br />
}<br />
if (get == "rWord")<br />
System.Diagnostics.Process.Start("winword");<br />
if (get == "rExcel")<br />
System.Diagnostics.Process.Start("excel");
Why is that so that only the one command work?

I can't imagine why it would be difficult. Just give us the facts, with all the relevant details, and you'll get an answer. Read my sig.
Here are just a few of the unclear points:
- are client and server on the same machine? if not:
- where is winword or excel to run? how is the client involved?
- which machine should shutdown? the server? can any client tell the server to shutdown?
And you should publish code inside PRE tags, that way you would have seen yourself that at least one of your code snippets will not even compile. Read my sig.

Aha! Now I understand. The problem is with these lines
string[] get_Split = get.Split('~');
int time = Convert.ToInt32(get_Split[1]);
Take the example of starting word. get is "rWord" get_Split will have length 1
ie:
get_Split[0] = "rWord"
the line
int time = Convert.ToInt32(get_Split[1]);
tries to access an array element that doesn't exist get_Split[1], this will throw an error.
This will work
if (get == "rWord")
System.Diagnostics.Process.Start("winword");
if (get == "rExcel")
System.Diagnostics.Process.Start("excel");
if (get.Contains("rshutdown"))
{
string[] get_Split = get.Split('~');
int time = Convert.ToInt32(get_Split[1]);
System.Diagnostics.Process.Start("shutdown", "-s -t " + time.ToString());
}

The two pieces of code aren't actually the same. You haven't just moved the string[] array, you've also moved the second }. Try this to see if it has any effect:
string[] get_Split = get.Split('~');
int time = Convert.ToInt32(get_Split[1]);
if (get.Contains("rshutdown"))
{
System.Diagnostics.Process.Start("shutdown", "-s -t " + time.ToString());
}
if (get == "rWord")
System.Diagnostics.Process.Start("winword");
if (get == "rExcel")
System.Diagnostics.Process.Start("excel");
}

@keefb
Thank you, you have understand my problem!
now i can open Word and so when i put the code on the Front place!
But now this code doesn´t work!
if (get == "rshutdown_without_warning")
System.Diagnostics.Process.Start("shutdown", "-s -t 0");
if (get == "rshutdown_abort")
System.Diagnostics.Process.Start("shutdown", "-a");
thank you at all!!!
EDIT:
I don´t know why but it works!
Thank you at everybody, it´s a very good forum, there are a lot of very clever people!

hi everyone.
i am looking for some help with my project.
i have x and y position and a string. i want to write that string in a text document at that x and y position.
can anyone pls help me
|

Does x and y represent a character index and a row index?
If you want to edit a text document then you need to read it, edit it, and write it to another file (temp) and then rename that file (with a File.Move) - unless you want to read all the file into memory then write it straight back to the original file, depends on file size really but I would avoid either way.
So you could use a System.IO.StreamReader to read the file a line at a time and write each one to temp file. Then when you get to the line you want to edit, add the data at the required position and write that line ti temp file. Then write remaining lines.

Here is one method:
1. Open a StreamReader
2. Open a StreamWriter to the new file
3. Do a ReadLine on the StreamReader y times, writing the result to the StreamWriter using WriteLine
4. On the Stream Reader Do a ReadBlock(x) and call Write on the StreamWriter, passing in the result.
5. Write the text to be inserted
6. Call StreamReader.ReadToEnd() and write the results to file using the Writer.
There are a couple of things to look out for:
a) The algorith I have given you writes to the correct position. There could be out-by-one errors (e.g. writing to a character or line before of after the one desired) as I haven't tested it.
b) You'll get exceptions if y is greater than the length of the file. Similarly, if x is greater than the length of line y, an exception will be thrown
Take a look at http://msdn.microsoft.com/en-us/library/system.io.filestream.aspx[^], the "HowTos" at the bottom contain "How to Read from File" and "How to Write to File" links which will be useful.

thank u.....
actually i have to create a new file and write the text at a particular X and y position.
how do i do that?
i have the position X and Y in pixels.
|
|
|
|

That's even easier. Open the StreamWriter and loop around y times calling WriteLine("") each time.
Next loop around x times calling Write(' ') assuming you want to use space as your padding character.
Call Write again, passing in the text you want to insert.
Again, you'll need to check the output file to esure the method I have given you is correct as I haven't checked it and it might all be out by one line and/or character.

That doesn't make any sense. Text holds characters and doesn't know about fonts and sizes, so pixels don't exist in the world of text.
Formatted text (such as a Word document, a Wordpad document, an HTML document) knows about formatting, but strictly speaking still does not know about exact pixel location.
If it is formatted text you're after, first thing to decide is which format to use.

luc i am sorry i am not able to understand u... can u pls explain me more

You'd confused your terminology. Pixels are the small dots that make up the screen display, normally associated with screen resolutions and graphins files.
e.g. a screen might show 1024 x 768 pixels, a bitmap is 100 pixel x 100 pixels etc
You used "Pixel" where you meant a character position (I think!)

i have x and y in pixels only.
i get that x and y from a xml. this xml is generated from a web application which contains many dynamically created 'div's. user will be able be move these div s around. on clicking save i store their pixel positions as attribute in xml.
now i need to write the value associated with each div s( which are again saved as an attribute) in their corresponding positions( ie x and y position)....
can anyone help me... pls

You could use the Graphics.DrawString method which will take either a System.Drawing.Point or x and y coordinates in pixels. Just look up DrawString on MSDN for documentation.

ya i already looked it up. but it doesnt write to file right? or does it?
|
|
|
|

No, it won't write to a text file. Like it was already said, text files aren't measured in pixels. If you have to save it to a file, the only way would be to save it in some image format. I suppose if you knew your printers resolution (dots per inch, etc..) you could print to a certain x,y location on the page, but as far as a text doc goes, there just aren't any measurements in pixels, so I don't believe it is possible to do exactly what you are wanting to do.
