Hi - I'm writing an application and using the SaveFileDialog which was working fine until I set the StartPosition to "CenterScreen". Once I did this, the 1st SaveFileDialog appears on top of my main form, however the remaining SaveFileDialogs appear behind my main form. I would like all the SaveFileDialogs to appear on top of my main form.
I think I need to make the main form the owner like back in my C programming days, but I'm not sure in C# or .NET if this is the problem, or how to correct it.
Thank you for your help,
Glenn

Yes, you're right. The form has an Owner property, all forms do. Set it before showing the form.

Pass the form that the dialog should appear on top of as the argument to ShowDialog. That is, use the ShowDialog(IWin32Window) overload. (Form implements IWin32Window.)

Thank you
But I can search on google too and I know those article
None of them are really usefull
The method used (swap cells) is odd and do not belong to binded datagridview
Also those article are not really fresh and since there are a lot of improvement in the framework
I was hoping to found something better

You'll find lots of experts on C# in here. However, I don't know much about statistics. What is "time series forcasting"?
Perhaps if you can explain how your forcasting technique works then we'll be able to help you. In fact, if you can describe it then you might actually be able to see for your self how to implement it in C#. Often the act of explaining a concept to someone helps you understand it better yourself, to such an extent that you answer your own question.

Hi All,
Im trying to run this code:
<br />
foreach (DataRow dr in ds.Tables["table1"].Rows)<br />
{<br />
if (dr[1].ToString() == "f")<br />
{<br />
dr[1].ToString() = "finish";<br />
}<br />
else<br />
{<br />
dr[1].ToString() = "not finish";<br />
}<br />
}<br />
But im getting the error:
The left-hand side of an assignment must be a variable, property or indexer
Could'nt find anything on google that solves this. Anyone a idea?
Thanx

You are assigning a value to a result of a function.

It is generally better to convert from object to a concrete type by casting, if you know what type an expression is, than to use a conversion function.
I would write this as
foreach (DataRow dr in ds.Tables["table1"].Rows)
{
if ( (string)dr[1] == "f" )
{
dr[1] = "finish";
}
else
{
dr[1] = "not finish";
}
}

Remove the toString() from dr[1].ToString() and dr[1].ToString()... Everything will work fine

Hi Justim,
this is not a compiler error at all; at best it is a compiler-generated error
message, due to a Justim error.

Hi All,
I'm just writing some code (or rather attempting to write some code) that will return an array of string containing one word each from a passed in string.
I've been looking at Expresso:
http://www.ultrapico.com/ExpressoDownload.htm[^]
I'm really new to C# so any and all tools I can find at the moment are a god send. Anyway, it looks like what i'm trying to do is really standard fayre in terms of using Regex. The code that Expresso creates is included in the code below:
private static void AnalyseTheFilePath(string pathtoanalyse)
{
Regex wordsplitter = new Regex(@"\w*(?x) # All words",
RegexOptions.IgnoreCase | RegexOptions.Multiline | RegexOptions.IgnorePatternWhitespace | RegexOptions.Compiled);
string[] words = wordsplitter.Split(pathtoanalyse);
}
However, the array I get back doesn't contain a single word ... the array has 9 entries that are either empty strings or " " of which there are 3 ... the string I'm passing in is "The String Is Horrid" ... When running the Regex pattern in Expresso it shows each word in [] which I assume to be saying "this is what will be in the array ...
Any ideas?
Thanks,
Jammer

The Regex you want to use is this:
\b\w+\b

Hi Paul,
Thanks for this. I've just tested it and its still doing something odd.
private static void AnalyseTheFilePath(string pathtoanalyse)
{
Regex wordsplitter = new Regex(@"\b\w+\b",RegexOptions.IgnoreCase);
string[] words = wordsplitter.Split(pathtoanalyse);
}
I'm just testing it with a string of "This String" which makes the words array like:
[0] ""
[1] " "
[2] ""
Not sure what to do as Expresso is evaluating your suggested Regex correctly for what I want to do as well. I must be missing something obvious.
Any Ideas?
Thanks again,
Jammer

Ahhh. worked it out!
private static void AnalyseTheFilePath(string pathtoanalyse)
{
Regex wordsplitter = new Regex("\\b\\w+\\b",RegexOptions.IgnoreCase);
words = new string [wordsplitter.Matches(pathtoanalyse).Count];
foreach (Match m in wordsplitter.Matches(pathtoanalyse))
{
}
}
Best,
Jammer

I am searching for a way to save a HtmlElement to a file.
private void webBrowser1_DocumentCompleted(Object sender, WebBrowserDocumentCompletedEventArgs e)<br />
{<br />
HtmlElement he = webBrowser1.Document.Images[0];<br />
}<br />
Hint: the webBrowser1 itself has a function called DrawToBitmap that can be used to grab a thumbnail from a webpage.
Bitmap docImage = new Bitmap(600, 800);<br />
webBrowser1.DrawToBitmap(docImage, new Rectangle(webBrowser1.Location.X, webBrowser1.Location.Y, webBrowser1.Width, webBrowser1.Height));
But i'm not sure how to do this with an image element inside my webpage.

Hey all!
I would love to get some help with the next subject:
I have an array list of structs. The structs contain 4 fileds. Now, I need to sort the array list by one of the fileds. The disired filed, that the array should be sorted by, is given by the user.
Now I indeed created a class of the struct with the 4 fileds, and created an array list of that struct in the main class. The struct class inherit the " IComparable" interface. Now from the main class i call the sort function.
The thing is - I don't know how to "inform" the toCompare method as for with filed from the 4 fileds to sort by?
Hope you understand. Thanks.

Instead of implementing IComparable for this, make a comparer class that implements IComparer. You can make one comparer class that can handle either of the fields in the data, or you can make one comparer specific for each field. To sort, you create an instance of the comparer class and use when you call the Sort method.
Unless you are stuck with framework 1.x, you should not use ArrayList at all. Also, unless you know exactly what you are doing, a class is a better choise than a struct. Given that you talk about a "struct class" (a contradition in terms), it seems like you should do some reading up before fiddling with structs... (No offence intended.)
Despite everything, the person most likely to be fooling you next is yourself.

I need a loop statement that changes what varible it is working upon each time it loops. The loop is changing the text of a label. The thing is I got frame1, frame2, frame3 all the way to frame0 and I need it to display them one at a time. So I was wonnering how I would do this.
Would I do something like this:
int thisFrame;
thisFrame = 1; \\for first frame
\\my display code
Text = frame?;
\\at the? it somehow uses thisFrame as the number so in this example it would be frame1
Is something like the above possible and if not how do I get the desired behaviour?

Since .NET we haven't had control arrays. You can create your own though. Simply create an array of frames and add your frames to it then you can iterate through them.
