The problem with my code at the moment is that it never goes to the second row, it will keep trying to query to the node detials. e.g: endless loop
I firstly pass the method the top node, and get its children.
So ExampleTopNode is passed to GetChildrenAndExpand, which inturn gets its children from the database and inserts it into the dataset (this works fine).
I then want to sort through ExampleTopNode's children which has now been inserted into "NodeInfo" table and get there children.
private void GetChildrenAndExpand(string Node_Name, string Node_Version)<br />
{<br />
GetChildrenFromDatabase(Node_Name, Node_Version); <br />
<br />
foreach (DataRow row in datatable.["NodeInfo"].Rows)<br />
{<br />
string NewNode_Name = row.ItemArray[0].ToString();<br />
string NewNode_Version = row.ItemArray[1].ToString();<br />
<br />
GetChildrenAndExpand(NewNode_Name, NewNode_Version); <br />
}

Gareth.

Maybe not exactly what you need, but it should give you the idea
<br />
DataTable is loaded prior to this call<br />
<br />
public TreeNode GetFolders()<br />
{<br />
DataRow[] rows = DataTable.Select("ParentID IS NULL");<br />
<br />
TreeNode parent = new TreeNode();<br />
parent.Text = rows[0]["Name"].ToString();<br />
parent.Tag = rows[0]["ID"];<br />
<br />
AddChildNode(parent);<br />
<br />
return parent;<br />
}<br />
<br />
private void AddChildNode(TreeNode node)<br />
{<br />
DataRow[] rows = DataTable.Select("ParentID=" + node.Tag);<br />
foreach(DataRow row in rows)<br />
{<br />
TreeNode child = new TreeNode();<br />
child.Text = row["Name"].ToString();<br />
child.Tag = row["ID"].ToString();<br />
node.Nodes.Add(child);<br />
<br />
AddChildNode(child);<br />
}<br />
}<br />

Thats not really what i want, as im not creating a TreeNode structure, and it doesnt really answer my question.
Thanks for trying anyways.

I see. Have you tried using setting a DataRelation and something like this
foreach(DataRelation relation in table.ChildRelations)<br />
{<br />
foreach(DataRow row in table.Rows)<br />
{<br />
childRows = row.GetChildRows(relation);<br />
}<br />
}<br />

I think your getting confused with with the wording in my first post. I am selecting from 1 datatable. I want to query data from a database and insert it into that datatable and at the same time, sort through the datatable for new rows which have been inserted and do the whole process again
E.g:
So, get data for bob, bob returns 3 peices of data, now get data for those 3 new rows but using the same method as in my first post.
Does that clarify it better?, the problem i beleive with my code is that im using a foreach loop to go through data which im inserting into, thus that loop will never see the new rows beeing added.

yes
but you should know what you want to give
what i think you need can be worked out as follows
create a report and let the user save it in desired format (crystal report have it built in)
if you want to do more you should use some more dlls provided by microsoft (for doc rtf xls ) and from adobe (for pdf)
and you should read office automation (sampels provided by microsoft will work fine)
hope that will help

You have to specify more clearly what you want to do
Yes, in C#, you can make an application that listens for incoming calls/transactions from the internet, or contact another application/server over the internet.
Find out exactly what you want/need to do and take a look at all the excellent tutorials here on CodeProject.
Best regards.

There's your problem, you'll have to take it from here I'm afraid.

Is this a Visual Studio 2005 Tools for Office problem?
If so, Visual Studio 2005 Tools for Office doesn't use ClickOnce manifest files, even though they are very similar. As a result, you can't run the .application file. The only way to run the solution is to start the Office program.

I have no idea, never used either technology (ClickOnce or VSTO, although I'm looking into trying out ClickOnce for one app I'm working on).

No. I use Visual C# Express 2005.
So I created a basic windows app and used the ClickOnce Publish to create the deployment files needed. That part completes fine, the moment that I run the executable file created by the publisher, I receive the error.

Hi all,
I am downloading a file from remote machine using webclient
as like as below,
<br />
WebClient oclient = new WebClient();<br />
<br />
oclient.DownloadFile(hostPath,localpath);<br />
1. here how can i ensure that the file is existing at the remote machine's path(hostPath) -(eg. same as like File.Exists() function ??)
2. during this operation if the file(localpath) had already opened, this download operation will throw the exception, in this case how should i show the opened file to the user.
3. During this download operation how can i detect the LAN connection failiure (disconnected )
|

1- The DownloadFile method will throw a WebException if the file does not exits. Examine the WebException's Status and Response properties.
2- Opened by the current process or another process?
3- Again, an exception will be thrown if this occurs.
You should experiment to know what exceptions are thrown in each of the cases, and what information those exceptions provide.

Hello
Can anyone give me a hint as to how I can override the font handling in a groupbox? I need to set the font style of a groupbox title/header to Bold, but that automatically results in all labels and other controls within the groupbox doing the same. Of course one can just set each of the childcontrols' font style to regular, but that gets more complicated when using more complex user controls/custom controls.
Therefore having the ability to set the header font of the groupbox to bold without affecting child controls is what I could need help to achieve.
Thanks!

when i am inserting data by inline sql then i am getting error like
Server: Msg 241, Level 16, State 1, Line 1
Syntax error converting datetime from character string.
and my inline sql is :-
INSERT INTO MShift (DayName,ShiftDate,ShiftEntryDate,ShiftStartTime,ShiftEndTime,
TotHour,PositionID,Department,Rate,HospitalID)
VALUES ('Wednesday',CONVERT(VARCHAR(10),'10/04/2006',121),'NULL','1200','2100','NULL','1','2','100',1)
due to the date i am getting error so pls tell me where i am wrong and pls rectify my error.
thanx....

I don't understand why you are converting the date. I assume that ShiftDate is a DateTime or SmallDateTime column then you should just be able to put the date in a string and it will work.
My only suggestion is that, as a general rule, you should use the ISO format yyyy-mm-dd so that the format of the date is culture independent.

how to select the border of the picture box in run time?
plez help

|
|
|

hello everyone.
Do you have an easy way when resize my windows form, proportionally to resize all components(Picturebox, buttons,textboxes, graphics etc.)
Thanks.
|
|
|
|
|
Check out the Anchor, Fill and Dock properties of the controls...
Splitter controls can help as well.
Good luck...
|
|
|
|
|
it depends what you need. Anchor and docking can do alot, but the only way I could grow two groupboxes 50/50 in a form was by handling resize manually. Everything inside the groupboxes was handled by a combination of standard means but the 50/50 thing proved elusive.
