I have inserted a DataGridViewCheckBoxColumn in a DataGridView. But whenever I click on its DataGridViewCheckBoxCell, the box is not checked. How do I check it? Is any event needed?
dgvcbc = new System.Windows.Forms.DataGridViewCheckBoxColumn();
dgvcbc.HeaderText = "Check to delete";
dgvcbc.Name = "Check to delete";
dgvcbc.CellTemplate = new DataGridViewCheckBoxCell();
dataGridView1.Columns.Insert(0, dgvcbc);
Thanks!

Hello
The problem is for sure NOT in the code that you've posted. Are other columns in the DataGridView working too?!! Maybe you've set the eable to false by mistake or something. The above code should work fine!!

Hi,
There is only one DataGridViewCheckBoxColumn in the DataGridView. Other columns are mainly DataGridViewColumn and DataGridViewLinkColumn. The links work perfectly.
You mentioned the setting problem. What do you think has been set to false by mistake? What is the code for that setting?
Thanks again.

Hello
Well, as I told you in my previous post, this code should work!! You can tamper with the settings of your DataGridView in a way that it may stop responding. I gave you an example. Check the Enable
Also check to see if you've made this column as ReadOnly. You can check both from the property grid.
When I asked about other columns, I meant are they working in any how?? Can you edit the cells??
Regards

Hi,
Do you mean the dataGridView.Enabled property? But it is set to true which allows user interaction. And the CheckBoxColumn isn't set to ReadOnly. So what else should I check?
Thanks!

Hello
Well, err... Yes! Forgive the typo. I mean Enabled.. I'm running out of guesses here. Try to add another CheckboxColumn, and see what happens. Also you didn't answer my question. Do other Text columns work? Can you type in them?

Hi,
It's working now. I found out that the datagridview is readonly though I checked that the checkboxcolumn is not readonly.
Anyways, thanks very much for your help.

I need to know how to edit a combobox on a web page in a webBrowser object (using MSHTML). The code for the combobox in HTML uses the SELECT and OPTION tags. I can check the checkboxes, fill the textfields and click the buttons, but I can't figure this one out. Any help would be appreciated! Thanks!

Sounds very much like a tailored program. And what do you mean by MSDN style exactly?!!
Also what Xml input will you give it to the program?

I would imagine he means that it functions like MSDN
Nader Elshehabi wrote: Also what Xml input will you give it to the program?
The XML that Visual Studio creates if you complile the assembly with the Produce XML Documentation project setting turned on.

I'm looking for something like JavaDoc in java.
Lets say you wrote a new class and you used the XML to write the API (or interface) of your class - all the public members of the class, and what do they do (so user will be able to use your class with ease).
in Java has JavaDoc.exe file that generate an HTML containing all that information from the source file itself.
since c# get only output XML I guess that there is a program that transforms the XML into an HTML (so it will, eventually, do the same as JavaDoc).
And by writing MSDN style, I meant HTML that looks like the MSDN APIs on the MSDN website.
hope it makes things a bit clearer

I was wondering how long it would take someone to point this out. 
As of how to accomplish this, have you ever tried Google?

Hi
Does anyone know how do i can open a network printer as a file in C#?
I am using a xerox printer and would like to be able to send 'VIPP' comands
to it easily once i have written a reusable class that will facilitate this.
I can open the printer and write a line to it in vb6 just like this:
Open FindPrinter("\\ip123\thePrinter") For Output As #1
Print #1, "%%XGF example print command" //this would be a special print command
Close #1
the equivalent in C# as far as i can see does not seem to work:
IO.StreamWriter swMyPrinter;
swMyPrinter = new IO.StreamWriter("\\\\ip123\\thePrinter");
swMyPrinter.WriteLine("Hallo\n");
swMyPrinter.Close();
this returns an error telling me i need to call 'CreateFile' myself and then
use 'FileStream' contructors if i want to open devices like this. I think
this type of thing may only allow me to open a local printer on LPT1 as it does
not seem to be able to open the handle to the printer.
Is there a simple way of opening a network printer for writing?
Thanks in advance
Edd

Hello
In C# you can't access ports -and other devices as well- directly using FileStream. I don't know why they didn't add this support though!! If you do it throws System.NotSupportedException with this message:
"FileStream was asked to open a device that was not a file. For support for devices like 'com1:' or 'lpt1:', call CreateFile, then use the FileStream constructors that take an OS handle as an IntPtr."
Now just like the message said, to access divice in C# as files do the following:
1- Use P/Invoke to call Win32 API function called CreateFile with the name of the device -in your case it will be @"\\Computername\Printer Share Name"
2- Retreive the handle to the device from the above function
3- Give that handle to one of the FileStream constructors overlosds that takes Argument 1 as a IntPtr
4- Now you have a FileStream object and you can access the device as a file

thanks for the quick reply
thats exactly the error message i got, after a bit of research I found a small tutorial on how to do this but didnt manage to successfully get it to work. I could well have done somehing completely wrong though (ive ben using c# for about 2 weeks so far so alot of this is quite daunting).
I shall endevour to give this another go when i get back to work.
thanks again

Does anyone know how to create an application that will work on a computer that does not have the .Net Framework installed? It keeps saying that it can't find the mscoree.dll file. Is there any way of puting it into the program so you dont need to install .Net Framework?
|
|
|
|

Hello
Sorry!! Not possible.
C# like any other .Net language was made for the .Net framework, and your C# apps won't work unless the .net framework was installed on the user's machine.
Anyway, you can include .Net framework in your deployment project as a prerequisite, and then the .Net framework will be installed on the user's machine with your application in a quiet mode -ie. the user won't know-.
Otherwise you will have to migrate your app to old fashioned C++.

Hi
I wrote a script in Visual Basic that selected an area in photoshop by the following script:
selRegion = Array(Array (0,0),Array(60,0),Array(60,60),Array(0,60),Array(0,0))
docRefNewPicture.Selection.Select(selRegion)
Now I want to implement this code in a C# project. I already wrote a script that opens the picture but now I wanted to select the area by the following code:
NewPicture.Selection.Select(selRegion,1,0,false);
In this code selRegion must contain the information about the area I want to select, but I have no idée how to define the area and in what kind of object or format. I already tried the following tinks:
int[,] selRegion=new int[,] {{0,0},{60,0},{60,60},{0,60},{0,0}};
(error only one dimensional arrays)
System.Drawing.Rectangle Rect=new System.Drawing.Rectangle(0,0,60,60);
System.Drawing.Region selRegion=new System.Drawing.Region(Rect);
(error array expected)
Can anybody help me how to define selRegion??
Tanks a lot

Hello
Your question is well organized but lacks some details.

Never heard of C# script?!! How do you open the picture exactly?? In photoshop, Component, or in your form?!!
Bauke Tilma wrote: NewPicture.Selection.Select(selRegion,1,0,false);
What is the type on NewPicture?
Bauke Tilma wrote: error only one dimensional arrays
Where is the prototype -ie. declaration- of the method that takes the selected area dimensions?
