how about this -
public String[] Split(String alpha)
{
String str = alpha;
List<String> returnVal = new List<String>();
Regex regexp = new Regex("[0-9]+");
MatchCollection matchColection = regexp.Matches(str);
for (int i = 0; i < matchColection.Count; i++)
{
returnVal.Add(matchColection[i].Value);
}
return returnVal.ToArray();
}

Assume that your input string like:
Input: a1f2g3r46mj5kde6
Output:123456
I think at first you split it in to an array and pass each array item to a function for numeric validation. That.s It...

I got InvalidComObjectException on exit on release build application. If I don't use RichTextBox, I don't see crash. In debug build application, I also don't see crash. On some release machine, even if I call CurrentDispather.InvokeShutdown won't eliminate crash.
My main appliation is a unmanaged MFC. The WPF control is embedded in CView in this MFC application.
Any idea or suggestion? Thanks.

I am currently using ControlPain.DrawBorder. it has 2 overloades.
DrawBorder(Graphics, Rectangle, Color, Int32, ButtonBorderStyle,
Color, Int32, ButtonBorderStyle, Color, Int32, ButtonBorderStyle,
Color, Int32, ButtonBorderStyle)
DrawBorder(Graphics, Rectangle, Color, ButtonBorderStyle)
With first overload, each size can be set a line width. However the second overload it doesn't. Is this a always constant? if not how can I programaticly acquire this info?

I am hosting WPF components in unmanaged MFC. This WPF components will do some ricktext editing. Hosting / editing are working fine but closing will crash application on exit (release version only and no crash on debug). The following is the current structure:
class parentA_COM : definited / implemented in unmanaged C++, STA
class memberB_COM : definited in unmanaged C++, but implemented in C# (ComVisible)
class winUserControl: implemented in C# to host WPF user control;
class wpfUserControl: implemented in C#
class MyApp // unmanaged C++
{
main ()
{
parentA_COM pPA(); // Initialize COM component
}
}
class parentA_COM // unmanaged C++
{
void get_hWnd()
{
m_ipMB.CreateInstance(xxx);
m_ipMB->get_hWnd();
}
private:
memberB_COM m_ipMB;
}
class memberB_COM : IDisposable, ... // C#
{
constuctor // initialize winUserControl
}
class winUserControl : UserControl
{
host WPF control wpfUserControl
}
How can I mark / make wpfUserControl / or winUserControl / or memberB_COM STA? Thanks.

Hi,
i'm "new" here and try to learn a little c#.NET
So for train a little i thought to write a software, copy a string into the search field of this page: http://www.dict.cc/[^]
After that the software should press the search button and list the items. would be enougth if someone of you can tell me how it works... i already started:
WebBrowser wb = new WebBrowser();
wb.Url = new Uri("http://dict.cc/");
HtmlDocument htmldoc = wb.Document;
// <input name="s" id="sinp" maxlength="100" size="25" style="padding: 2px; width: 340px;" value="" type="text">
htmldoc.All["sinp"].InnerText += richTextBox1.Text;
// <input id="submit" value="Suche" class="inp1" style="padding: 1px;" type="submit">
htmldoc.All["submit"].InvokeMember("Click");
this does not work, i always get the following error for the last 2 lines: "NullReferenceException was unhandled"
and i don't know how to go on... so wait for the response and read the first answer..

Ok, i think you missunderstood something.
The page already exists and i want to write a Windows Forms Application in C#.
I never worked with the NET libraries of .NET before and i've read a lot and tried to start. And as OriginalGriff told me to debug, i've already done...
I found an article with "How to login to gmx with C#" and i start to build.
I just want to know how to use the WebBrowser without using it as controle, how to fill fields, press buttons and wait for an response. I hoped that you can give me some usefull links with some explanations or some open source software to read and rewrite.

Hi,
if you don't want a user to interact with a WebBrowser Control, then you should not use one.
Use HttpRequest and HttpResponse classes instead.
|
|
|
|
|
There are a lot of things in your code which could be causing this, and the best way to help you is not for me to guess! You need to learn how to debug this - you will be doing this a lot, so learn now.
Put a break point on the line "WebBrowser wb = new WebBrowser();" and run your program in the debugger. When it stops on the line, use the single step ("Step Into") button on you toolbar to follow the code through. Check before you execute what the contents of each variable are - you will soon find the null reference.

I am iterating through all of the bookmarks in a word document.
I am able to retrieve the bookmark names, but unsure how to retrieve the bookmark values?
Here's a code snippet that I'm using to get the bookmark names and it's working great, but I also
need to get the value (text) for each bookmark.
Microsoft.Office.Interop.Word.Document doc = oWord.Documents.Open(... arguments...);
doc.Activate();
for (int i = 1; i <= doc.Bookmarks.Count; i++)
{
object bkmk = i;
MessageBox.Show("Bk: " + doc.Bookmarks.get_Item(ref bkmk).Name);
}
Thanks for any help.
|
|
|
|
|
Maybe this will work for you:
string value = doc.Bookmarks.get_Item(ref bkmk).Range.Text;

Well, Sparky, we can't read it because it's not formatted properly.

I'm trying to implement a checkbox in a DataGridView in a WinForms app. I am creating the DataTable, then binding it to the DataGridView:
DataTable table = new DataTable();
table.Columns.Add("ColumnId", typeof(int));
table.Columns.Add("QueryId", typeof(int));
table.Columns.Add("TableId", typeof(int));
table.Columns.Add("TableName", typeof(string));
table.Columns.Add("ApexColumnName", typeof(string));
table.Columns.Add("Expression", typeof(string));
table.Columns.Add("MyCheckBox", typeof(bool));
dsGrid.Tables.Add(table);
grdData.DataMember = dsGrid.Tables[0].TableName;
grdData.DataSource = dsGrid.Tables[0];
The checkbox column appears, but when I add a row, the check the checkbox, nothing happens. No checkbox appears.
Everything makes sense in someone's mind
|
|
|
|
|
The ReadOnly property on that column is probably set to true.
|
|
|
|
|
I set it to true, and no change.
When a checkbox is set to true in code, and cannot be unchecked when run
Everything makes sense in someone's mind

Try building the DataGridViewColumns instead of letting the datagridview create for you. Also check if the column in datatable is readonly (if there's such a flag, seldom use datatable for displaying nowadays).

Good morning.
I am trying to figure out how to set the focus to a textbox when a user clicks on ctrl + L. I have the following:
private void button1_Click(object sender, EventArgs e)
{
this.tstbAddress.Focus();
}
When I tried this in and of the key methods, it didn't work. I have a webbrowser control on the form. I thought it might have something to do with (lack of) focus.
Any suggestions? Thank you, WHEELS

Hi Wheels
In the forms KeyDown event you will have access to more in the KeyEventArgs so you can identify if the control key and L key are being pressed at the same time. You will need to set the KeyPreview property to true on the form then the following will work
private void Form1_KeyDown(object sender, KeyEventArgs e)
{
if (e.Control && e.KeyValue == 76)
textBox1.Focus();
}
