Are you using a trial version of a library with a hard (trial) limit? Seen this sort of behaviour before, along with only playing the first few seconds of a track
C# has already designed away most of the tedium of C++.

I am using a hyperlink in a datagrid. When clicked I want to open the file with Process.Start:
private void DG_Hyperlink_Click(object sender, RoutedEventArgs e)
{
Hyperlink link = (Hyperlink)e.OriginalSource;
var fileName = link.NavigateUri.AbsolutePath;
fileName = fileName.Replace("file:///", "");
fileName = Uri.UnescapeDataString(fileName);
Process.Start("notepad.exe", fileName);
}
For local files this works fine. With network files the path is different:
/n/folder/folder/folder/thefile.txt
The file is on the N: share. The path is somehow formatted to start with 'n/'.
What's wrong here?
Thanks

I'd start by looking at your original unmodified share path - if it is in the form /n/folder... or even file:///n/folder/... but it should be on the N: drive instead of the N folder of the current drive root then it's wrong: it doesn't specify a drive at all, and that probably needs looking at rather than "bodging around" to get it working.

Replace the : in the path with a pipe |:
file:
|
|
|
|
|
Try something like:
Hyperlink link = (Hyperlink)e.OriginalSource;
Uri path = link.NavigateUri;
string fileName = path.IsFile ? path.LocalPath : path.AbsoluteUri;
Process.Start("notepad.exe", fileName);

I've got this chuck of code. It looks for different phrases in a line of text being read from a file, then extracts the data at the end and stores it to various properties. The data will be either an IN RANGE or OUT OF RANGE message:
"Denature 1 RTD in range. Reading: 9.64241027832031"
or
"Detection 2 RTD out of range. Reading: 510"
I have 5 different properties that need to be set from the data. I would like to make this into a method call but how would you pass in the property?
The first word of the line determines which property to be set.
var index = line.IndexOf("Denature 1 RTD in range. Reading:");
if (index > -1)
{
var data = line.Substring(index + 33);
((RTDTestModel)model).Denature1ActualValue = Convert.ToDouble(data);
}
index = line.IndexOf("Denature 1 RTD out of range. Reading:");
if (index > -1)
{
var data = line.Substring(index + 37);
((RTDTestModel)model).Denature1ActualValue = Convert.ToDouble(data);
}
index = line.IndexOf("Extension 2 RTD in range. Reading:");
if (index > -1)
{
var data = line.Substring(index + 34);
((RTDTestModel)model).Extension2ActualValue = Convert.ToDouble(data);
}
index = line.IndexOf("Extension 2 RTD out range. Reading:");
if (index > -1)
{
var data = line.Substring(index + 38);
((RTDTestModel)model).Extension2ActualValue = Convert.ToDouble(data);
}
Thanks

Something like this:
private List<string> terms = new List<string>();
terms.Add("Extension 2 RTD out range. Reading:");
terms.Add("Denature 1 RTD in range. Reading:");
terms.Add("Denature 1 RTD out of range. Reading:");
foreach (string term in terms)
{
if (Parse(term))
{
break;
}
}
private bool Parse(string text)
{
int index = line.IndexOf(text);
if (index > -1)
{
string data = line.Subsctring(index + text.Length);
double value;
if (double.TryParse(data, out value))
{
((RTDTestModel)model).Extension2ActualValue = value;
}
}
}

Ya, but the problem is that there is a different property to set for each term
For example, for "Extension" there are two properties, Extension1, and Extension2. Same for Denature, Sample, Anneal, Detection, etc...
The structure of the file is the same for each setting. There are just different settings whose values need to be captured to various properties on the model.
A generic property reference would be nice. Something like:
void MyMethod(string term, T TheProperty)
{
.
.
.
}
where the property is passed as in
MyMethod("Anneal1", model.Anneal1);
MyMethod("Anneal2", model.Anneal2);

model.GetType().GetProperty( name ).SetValue( model, value );

hello,
i really need help, i have created a dynamic datagridview, which the number of rows i write it in a xml file. When i save it for first time, in the xml file write the correct number of rows but when i save it again the "new" xml file write zero rows! i can understand why. i try to use datatable and dataset but nothing the problem is that datagridview hasnt rows.
Please some idies?
Thank you
public Form1(int cntC, int cntL)

Yeah, there is no way anyone is going to be able to answer this because we can't see your code. Modify your question and post the relevant code that saves your data to the XML file.

Hi,
I'm mostly asp.net/services soa/ server code .. I'm have done Win Form apps but installations is not something I have much XP with ..
Question : I have a config file and an encrypted file that I need to write during installation. The directory I was going to use is commonappdata(ProgramData) directory. I was just wondering if this is typical or has everyone found something better for reasons unknown to me .. Win7+
Thanks
Jon

I'd use the special folders: Where should I store my data?[^] - combining the standard "writable" folders with a GUID based app id for your installed app makes it easy for you, but harder for the user to find. Which is probably a good idea if you are writing an encrypted file as some kind of licence.

hello sir I m Ramesh .net fresher I want to develop a desktop software in accounting software using c# . how to do this task please help me sir

You start by researching the requirements of the accounting software. Once you know the requirements you can start the actual design: inputs, outputs, data storage etc., etc. As a beginner I would suggest you would probably be better working on some smaller projects first.

As Richard said, you would start off by researching the requirements for accounting software. Long before you type your first line of code, you should understand what it is that you are trying to develop. Do you have an accountancy background? If so, that will help you. If not, you are going to have to talk to accountants to get an understanding of what they require. To give you an example of why this is necessary - consider the case of Value Added Tax (VAT). Will your system be able to cope with VAT added at source? What about VAT that gets applied at destination. Can you cope with different VAT rates? What about the ability to have VAT discounts (where VAT is applied at one rate for part of the year, then another rate for the rest)?

What be this VAT thing you talk about.
And that is the point, is it going to be an international package or just for his home country.
