iv been trying to find some reasonable info on how to Bind DataBase Field to Column BackColor Property.

this only binds the data grids main properties back color but i need the individual Column to be bound.

dataGrid1.DataBindings.Add("BackColor",DataSource,"DataSource.Field");

Does what is below have anything that can lead me to it?????

// Use a PropertyDescriptor to create a formatted column.
PropertyDescriptorCollection myPropertyDescriptorCollection = BindingContext
[myDataSet, "Table.Field"].GetItemProperties();

// Create a formatted column using a PropertyDescriptor.
DataGridColumnStyle csField =
new DataGridTextBoxColumn(myPropertyDescriptorCollection["Property"], "c", true);
csField.MappingName = "Property";

Hello Hoang Dung,

I think MSHFlexgrid only works with VB but not 100% positive. Try the following Link and you'll see MSHFlexgrid is listed under VB 6.0.

you can use a flexi grid in C# , just add it to the toolbox :
VB:

<font color="blue">Private</font> <font color="#0000FF">void</font> button6_Click(<font color="blue">Object</font> sender, System.EventArgs e)
        {
            <font color="blue">For</font> (<font color="#0000FF">int</font> i=0;i<20;i++)
            {
                axMSFlexGrid1.AddItem("item\t" + i,0);
            }
        }

hope that helps. Smile | :)

<font color="blue">Private void</font> ExpectingTwins(<font color="blue">string</font> twins)
    {    
    <font color="blue">switch</font>(twins)
    {
    <font color="blue">Case</font> ("twins on the way"):
        MessageBox.Show("for mr and mrs dynamic","twins on the way");
    <font color="blue">break</font>;

Scaling the HTML page

How I can show a html page in Windows Form and scale the whole document to a smaller size. It's like when you browse a hard disk and click on html page then you can see a small preview of this page on the bottom-left in Explorer. So the quaestion is - how I can make this 'preview' window in C# ?

There probably is a better way, but here's one that almost has to work.

Open a hidden web browser, and load the desired page. Capture the image from that browser's screen, scale it down, and display it where you want it.

Inheritance Picker Dialog/Form Unreadable! Anyone?

Hello again gurus,

When you add a INHERITED Form to your project, you get to a form named "Inheritance Picker". This form is very small in size and the items in the list are so tiny. It's a pain to figure out what to select on my monitor.

If gurus have any ideas how to improve it, I appreciate your tips so much.

Thanks again and have a great day

Getting used file handles of a process

Hi!

I am writing a kind of spy tool in c#. Now I need to find out what
files are currently used (opened) by a certain process (knowing the
processid).

I know that there is this undocumented windows function
NTQuerySystemInformation, but I hope that there is another solution.

I tried NTQuerySystemInformation, but as I am not an interop-expert
I could not make it work Frown | :(

...

Is there anyone that solved that problem once, or has a code example
on how to invoke NTQuerySystemInformation in c#?

Code Download, amount downloaded

Hi
We are doing a client-server project for a chain of shops. The individual shops connect to the server using a 128 Kbit connection so we are very concerned with the amount of data being transfered.

We want to implement the client applications as smart client and deploy them using "Code Download". Can anyone answer the following questions concerning Code Download?:

1) The client app. consists of a single .exe file and a number of .dll files. What will happen if we update one of the .dll files? Will the client need to download all of the files again, need to download the .exe file and the changed .dll file or only the changed .dll file?

2) How is the above implemented if we want to download as little as possible? Is it all done automatically, do we need to a Assembly.LoadFrom() for each of the files, do we need to update the client manually if a need .dll is downloaded etc.

3) The client app. consists of only a single .exe file. If the .exe file is changed, will it be necessary for the client to download all of it or is it possible to download only "the changes" in the file?

Thanks for your help, Mads Unsure | :~

These type of questions are exactly what the docs were written for. Check out www.msdn.com and look in the MSDN library if you don't have the docs already.

From memory, only changed files download again. All of the file is downloaded.

Hi
You should be able to use where with datareader, e.g.:

SqlCommand cmd = conn.CreateCommand(); // conn is a SqlConnection
cmd.CommandType = CommandType.Text;
cmd.CommandText = "SELECT * FROM Customers WHERE Id = 2134";
conn.Open(); // with datareader you have to open/close connections manually
SqlDataReader dr = cmd.ExecuteReader();
while(dr.Read())
{
// do something...
}
conn.Close();
conn.Close();

Hope this can be of use, Mads Big Grin | :-D

Name parser

Hello all,
Does anyone have source code for parsing a person's name? For example:
Dr. John Q. Smith III would be parsed into:
var.Title = "Dr."
var.FirstName = "John"
var.MiddleName = "Q."
var.LastName = "Smith"
var.Generation = "III"

or Smith, John Quincy would be parsed into:
var.Title = ""
var.FirstName = "John"
var.MiddleName = "Quincy"
var.Lastname = "Smith"
var.Generation = ""

or Mr. Jose N. Del Valle would be parsed into:
var.Title = "Mr."
var.FirstName = "Jose"
var.MiddleName = "N."
var.Lastname = "Del Valle"
var.Generation = ""

Thanks all.

I would have a look at the String.Split method

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
