Hi,

It looks like....(small sample)

- <newdataset>
- <schematable>
<columnname>F1
<columnordinal>0
<columnsize>8
<datatype>System.Double
- <schematable>
<columnname>General
<columnordinal>1
<columnsize>255
<datatype>System.String

- <schematable>
<columnname>Number
<columnordinal>2
<columnsize>8
<datatype>System.Double
- <schematable>
<columnname>Currency
<columnordinal>3
<columnsize>8
<datatype>System.DateTime
........(it continues till end of file).

Here ,i need the node DataType datas(sys.string,sys.double...) alone to fetched and stored in an array for further purpose ...

How to do it?Help me

Thanx...

I think you can read the contents of the nodes only as strings. Once you've read the content of a node, you could try Int32.Parse(), Double.Parse() and so on, and see if what you've read is an int or a double or a string.

HTH. Smile | :)

Cheers,
Vikram.

Assuming you'll be using DOM style parsing, load the document using XmlDocument[^] and iterate through the nodes, using the Value[^] property to get the actual value.

Something like

XmlDocument doc = new XmlDocument();
doc.LoadXML(strXML);
foreach(XmlNode node in doc.DocumentElement.ChildNodes) // replace this with code for your hierarchy
   Console.WriteLine(node.Value);

MDI parent and panels

madhusri18-Dec-05 18:38

18-Dec-05 18:38

I had created an MDI application for Touchscreen based dvpt using C# .net.
I have placed 3 panels in the MDI parent. The Top panel, left panel and center panels. The top panel displays the application name. the left panel displays the navigation buttons. The center panel displays the necessary details. Here i need to pop-up some windows to display some details. the pop-up windows are child forms. When i set the parent and pop-up these windows, they hide at the back of the panel and are not visible. If i do not set the mdiparent then they are visible. How can i overcome this problem?

Regards,
Madhu Srinivasan

The centre panel is blocking the child MDI windows. You can either get rid of the centre panel and place your user controls elsewhere, say the toolbar, or set aside an area within the centre panel, maybe another panel, and set this as the parent of the child windows (the child windows would then be normal windows, not MDI children, and set the WindowState to Maximized.

I am leaaving for work now, but if you are still having problems, e-mail me a *small* sample project and I will take a look at it when I get there.

If you only need to reference the main form from the sub-forms, then you could just set the Owner property after it is constructed.

ie from the main form:

NewSubForm form = new NewSubForm();<br />
form.Owner = this;<br />
form.Show();

...in the sub-form:
this.Owner.Text = "New Caption";

I recently found that you can associate a file type with an application through creating file types in a setup project. However, how do you handle loading the file when you double click it? Say to load all of the elements within the file into a dataset and then a sorted list?

Thanks

Re: Create File Format

S. Senthil Kumar19-Dec-05 0:25

All the setup program does is associate the file type with an executable. It usually registers something like

YourApp %1

so that the file you double clicked on will appear as a command line parameter to your app. Assuming it's setup that way, all you have to do is check for the file name in Main and do the required action.

Senthil

Applying new proxy settings to a browser control

pieterman18-Dec-05 16:18

18-Dec-05 16:18

Hi,

I've a activex browser control in a form. I've added proxy server support to the control by modifying the proxy server settings in the registry. This works fine before the browser control is created (the browser control is only created after a button on the form is pressed). However, once the initial proxy settings are commited and the browser control is created, the browser control does not respond to any new settings even though the registry shows the correct new settings. The browser control seems to be "stuck" on the old settings. How does IE apply any new settings?

Any suggestions?

Thanks

Double quotes within a string

Hi How I add double quotes to a string.
For instance, I have following;

string s1 = "first string";
string s2 = "second string";

Now I want to combine the two and the result should be:

"first string , second string" (Note: the stirng should contain the starting and ending double quotes")

regards

Re: Double quotes within a string

[Marc]18-Dec-05 14:36

You have to escape them with \

string s1 = "\"first string";<br />
string s2 = "second string\"";<br />
<br />
string middle = " , "<br />
string combined = string1 + middle + s2 <br />
You get: "first string , second string"

You have to use escape characters.

string s1 = "first string";
string s2 = "second string";

string result = String.Format("\"{0}, {1}\"", s1, s2);

How can I hide a new app started with Button1

My dilema is I have an app that on Button1 starts another app that I need hidden.
So my question is how can I make it so the app that Button1 starts stays hidden?

I appreciate any help,
Thank you

Here is what I have and I have tried every thing to no avail.

Process myProcess = new Process();<br />
myProcess.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;<br />
myProcess.StartInfo.FileName = "foo.exe";<br />
myProcess.StartInfo.CreateNoWindow = true;<br />
myProcess.StartInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;<br />
myProcess.StartInfo.FileName = "c:/program files/MyHiddenapp/foo.exe";<br />
myProcess.Start();<br />
myProcess.WaitForExit();

Ultimately, you can't control what the app itself does. If the app forces itself to be shown, there's nothing you can do about it.

I don't think thats the case with this, as there is a windowHider app tutorial that will hide it - I may be wrong and the method is different - But I'm pretty sure the right person will know how to either hide it or minimize to tray anything that will remove its Ugly console face from in front of the Primary app. Laugh | :laugh:

Console app? Then you've already done it the correct way.

Process proc = new Process();
proc.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
proc.StartInfo.FileName = @"NSLOOKUP.EXE";
proc.Start();

Works perfectly fine for me. No console window shows up.

[EDIT]
Might help if I posted the correct language...
