It would appear to me that you are the one using profanity (badly spelled profanity at that)

True, you said "provide me code". But "provide" implies that the person you asked must do the work to create the code, or do the work to find the code. Either which way, you are asking others to do your work. Perhaps if you had phrased your question in a less provokative way you would get a better response. e.g. "Help me find the code" that implies to are trying to do the work but need assistance. We like to help people. We especially like to help people that show that they are trying to help themselves.

 I can only imagine that is some idiomatic expression literally, rather than figuratively, translated.

Hello,
I have a data grid view, and what I am trying to do is, grab all the column headers and put them into a combo box or list box.
what I have so far is:
foreach (DataColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.ToString());
}
I get an error with this, it is:
"Unable to cast object of type 'System.Windows.Forms.DataGridViewTextBoxColumn' to type 'System.Data.DataColumn'"
Any help would be apreciated.
Thanks
J

you can try:
foreach (DataColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.HeaderText);
}
|
|
|
|
|
|
Thanks... The end result that I ended up with is:
foreach (DataGridViewColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.HeaderText);
}
|
|
|
|
|
this.dataGridView1.Columns returns a collection of GridViewColumn, not DataColumn. In this case, the column returned is a specialized version of GridViewColumn which contains a textbox.
<br />
foreach (GridViewColumn in this.dataGridView1.Columns)<br />
{<br />
this.listBox1.Items.Add(column.HeaderText);<br />
}<br />

Thank you for your help, I added a identifyer, and it worked great! Thanks.
Here is the end result.
foreach (DataGridViewColumn column in this.dataGridView1.Columns)
{
this.listBox1.Items.Add(column.HeaderText);
}

hi all
abstract class c
{
abstract function()
}
class c1:c
{
override fucntion()
{
//
}
void function()
{
}
}
class c2:c1
{
c1 obj=new c1()
obj.//how do i differenciate that i wanna call overrided function and ordinanry function of c1
|
|

|
|
c.function will always call the overrided method. You cannot call the base one. If that's what you want, don't use overrides, using hiding:
class Base
{
public void Foo() { ... }
}
class Derived : Base
{
public new void Foo() { ... }
}
Base obj = new Base();
obj.Foo();
Derived derived = new Derived();
derived.Foo();

Hello,
I'm having a problem that I thought would be very easy to fix. It could just be something small I am missing. I am loading a string that contains an XPath query. Inside the string I have a couple variables being loaded from an XML request. My line: XmlNodeList regionList = root.SelectNodes(xpathRegion); is throwing an exception when the variable includes an ' like Amp'd for example. I can check for characters easy enough and remove that character, but I actually need to leave it as the query needs to search based on the exact name.
I am trying the following:
string oldText = catName;
string newText = oldText.Replace("'", "\\'");
I figured this would escape the first slash, and replace the ' with \' but it actually shows up as \\'
if I change the line to string newText = oldText.Replace("'", "\'"); only the ' shows up in the string.
I can't seem to get newText to contain Amp\'d so that when used in the XPath it finally ends up the way it was.
Is there a different method I should use, or am I making some type of beginner error? Thanks,
Forrest

Thanks for the link. This is certainly a great resource to have. It looks like the Xpath string is still blowing up even with a \'
|
|
|
|
|
instead of \', have you tried ' instead?
|
|
|
|
|
Yes, and " Those values are inserted into the string, but I guess it is not read as an xpath query since I still get an invalid token message.
|
|
|
|
|
Try this and see if it works:
string oldText = catName;
string newText = oldText.Replace("'", @"\'");

Thanks Chase. This is exactly what I needed to do to get the string to contain \' BUT it looks like the xpath string is still blowing up when SelectNodes() is called. I don't think it recognizes the escape sequence. I also tried including ' but it didn't recognize that either. I do appreciate the help though.

Hi folks,
I have a deployment project which set's up registery entries for using redmonnt.dll and any other things which are neccessary.
First I create a printer setup over the redirect port manually and extract all entries from the registry. (I hope they are all  )
This procedure produces a printer icon within the printer explorer and provides a new available printer in the print dialog of applications.
If I run my installer all reg entries were made (device, port, ...), but no printer icon is available and my printer is inaccessible to the applications print dialog.
Do you have me some hints, what additional work do I need to do.
Thanks.

Ok, I know it is long...
In an OpenFile() routine I am trying to change the color on the text of a file at a specific position, and do this prior to it loading into a RichTextBox.Text property. I can do this with the findSequenceNumbers() routine below;
If I do it after it loads by using the findSequenceNumbers() routine it takes about 3 - 4 minutes dpending on the file size as it scrolls thru the text box.
I want to perform this formatting using the RichTextBox.RTF property however I do not understand it, nor do I understand where I would fit it in. I did create the file and save it after I formatted it as an RTF document and when I open it in a text editor this is what is at the top;
{\rtf1\ansi\deff0{\fonttbl{\f0\fnil\fcharset0 Courier New;}}
{\colortbl ;\red0\green0\blue139;}
\viewkind4\uc1\pard\lang1033\f0\fs20
A formatted line with the color change looks like this;
2007/08/13 14:00:03 [144007]ARES_EINDICATION 010.050.016.010 420.1.01 (6901) RX 68 bytes 69 01 26 02 28 A4 AA 20 76 96 51 44 50 76 08 45 46 00 34 02 02 C7 88 \cf1\b 01\cf0\b0 C7 88 AA 50 76 08 45 46 20 76 96 51 44 D7 07 08 0D 0D 3B 3B 00 00 10 06 0A 06 06 06 06 06 06 0A 0A 06 06 06 06 0A 0A 9B 67 5F 91 F8 \par

Hi!
Although I cannot really follow what you're trying to do, it seems as if a different way would be much easier:
Create a (invisible) RichTextBox, load the RTF document into this box, find the lines you want to colorize using the Text property of the RTB, select them and then assign the SelectionColor you want.
Afterwards you can simply assign the invisible RTB's Rtf property to the target RTB and you're done.
If you really want to modify the RichText yourself, I suggest reading the Rich Text Format (RTF) Specification, version 1.6[^], but a quick scan through the introduction will show you that it's not as easy as you might think.
Regards,
mav
