That is bizzare ... no wonder I couldn't find any documentation stating that events are suppressed when visibility is changed to false. My solution is in VS2003 (1.1) and unfortunately, cannot convert to VS05. I'll see if there something funky going on in my machine.
Thanks,

Do you have .NET 1.1 SP1 installed?
You can find out if you go to Help->"About Microsoft Visual C# .NET" and look at the version on the Microsoft .NET Framework 1.1. Mine is 1.1.4322 SP1.
This may be one of the many, many bugs[^] addressed in SP1.

I don't think that you can. If you set it to display 10 rows. Then 10 rows will be displayed. The height of the grid will change if any of the text is wrapped. You could put the grid inside a div tag.
Somthing like this.
<div style="OVERFLOW:auto;WIDTH:400px;HEIGHT:500px">
datagird
</div>

i want to add Menu>Submenu dynamically, depending upon the data i receive. till now i did :
<br />
MainMenu mnuMain = new MainMenu();<br />
<br />
MenuItem mnuFile = new MenuItem("&File");<br />
MenuItem mnuMod = new MenuItem("&Module");<br />
<br />
mnuMain.MenuItems.Add(mnuFile);<br />
mnuMain.MenuItems.Add(mnuMod);<br />
<br />
MenuItem mnuFExit = new MenuItem("E&xit", new EventHandler(mnuFExit_Click),Shortcut.CtrlX);<br />
<br />
mnuFile.MenuItems.Add(mnuFExit);<br />
<br />
foreach (string strKeyName in arrValue)
{<br />
mnuMod.MenuItems.Add(strKeyName,new EventHandler(mnuModMenu_Click));<br />
}<br />
till here it's working perfectly. now i want to add submenu to those menu i'v added dynamically. only i have the text of those menu(strKeyName), but don't have any name so can't add menuitems referring them. how can i do that?
|

You could try something like:
foreach (string strKeyName in arrValue)
{
mnuMod.MenuItems.Add(strKeyName, new EventHandler(mnuModMenu_click));
foreach (MenuItem mi in mnuMod.MenuItems)
{
if (mi.Text == strKeyName)
{
}
}
}
Obviously this assumes that the Text value of each menu item is unique. However, if you have duplicates in the menu it will confuse the user... so take it for what its worth.

ya, that's the main problem, it's will not only confuse the user but also make coding harder. and most important thing is it's not possible to go with the assumption that every text will be unique. like if i build a library system(for an instance) i may have menu like --> Book > Add ; Member > Add
now on click of both add i get that "Add", and my program can't understand which "Add' has been called? Can you give any solution?
Beside this i was trying to pass the name through variable, i've tried that in sevaral way but none worked out. if i want to pass the name through a string/array how can i do that? like :
MenuItem strMenu = new MenuItem(); //considering strMenu has some value as the name of the menu
though this code is wrong, i'v just written it to explain my query.
And Thanks for your reply

You could save the MenuItems in an array:
MenuItem[] menuItems = new MenuItem[arrValue.Length];
for(int i = 0; i < arrValue.Length; i++)
{
menuItems[i] = mnuMod.MenuItems.Add(arrValue[i], new EventHandler(mnuModMenu_Click));
}
menuItems[i].MenuItems.Add("First submenu's first item", new EventHandler(...));Just remember that if you use the same event handler, you'll have to identify in it which menu item was selected, and if you didn't save all the MenuItem references, you'll have to do it by text.

Hi All,
I am creating a class with a Hash Table as one of its objects. I am taking Hash Table as one of its members because, i need a key value pair there.
After creating the Object, i need to serializing the object into an XML file.
Obviously, it will throw an error, as hash table cannot be serialized.
How will be able to serialize such a class then. I need the hash table inside this class object only.

I try to implement drag and drop in .NET FrameWork 2.0. The code below works fine. You have to drag one node onto the other. The problem is that the exception is lost. When I call the failing function via the button everything is fine, the exception comes as expected. But when I do it from drag and drop nothing happens, the exception disappears as if handled by an external code in the FrameWork. Am I doing something wrong?
The form contains only a treeview with two nodes, and a button:
using System;<br />
using System.Collections.Generic;<br />
using System.ComponentModel;<br />
using System.Data;<br />
using System.Drawing;<br />
using System.Text;<br />
using System.Windows.Forms;<br />
<br />
namespace DragAndDropTest<br />
{<br />
public partial class Form1 : Form<br />
{<br />
private TreeNode previousTarget;<br />
<br />
private void FunctionThatFailes()<br />
{<br />
throw new ApplicationException("Something is wrong");<br />
}<br />
<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
}<br />
<br />
private void treeView1_ItemDrag(object sender, ItemDragEventArgs e)<br />
{<br />
treeView1.DoDragDrop(<br />
treeView1.SelectedNode, DragDropEffects.Move);<br />
}<br />
<br />
private void treeView1_DragDrop(object sender, DragEventArgs e)<br />
{<br />
TreeNode source = e.Data.GetData(typeof(TreeNode)) as TreeNode;<br />
TreeNode target = previousTarget;<br />
ResetPreviousTarget();<br />
FunctionThatFailes();<br />
target.Text += source.Text;<br />
}<br />
<br />
private void ResetPreviousTarget()<br />
{<br />
if (previousTarget != null) {<br />
previousTarget.ForeColor = SystemColors.WindowText;<br />
previousTarget.BackColor = SystemColors.Window;<br />
previousTarget = null;<br />
}<br />
}<br />
<br />
private void treeView1_DragOver(object sender, DragEventArgs e)<br />
{<br />
ResetPreviousTarget();<br />
<br />
if (e.Data.GetData(typeof(TreeNode)) != treeView1.SelectedNode) {<br />
e.Effect = DragDropEffects.None;<br />
return;<br />
}<br />
<br />
TreeNode target = treeView1.GetNodeAt(<br />
treeView1.PointToClient(Control.MousePosition));<br />
if (target == null || target == treeView1.SelectedNode) {<br />
e.Effect = DragDropEffects.None;<br />
return;<br />
}<br />
<br />
e.Effect = DragDropEffects.Move;<br />
<br />
if (target == previousTarget) {<br />
return;<br />
}<br />
<br />
previousTarget = target;<br />
<br />
target.ForeColor = SystemColors.InactiveCaptionText;<br />
target.BackColor = SystemColors.InactiveCaption;<br />
}<br />
<br />
private void Form1_Load(object sender, EventArgs e)<br />
{<br />
treeView1.AllowDrop = true;<br />
}<br />
<br />
private void button1_Click(object sender, EventArgs e)<br />
{<br />
FunctionThatFailes();<br />
}<br />
}<br />
}

Just a guess, but the .NET framework may contain error handling for drag and drop to prevent anything horrible from occuring; for if an exception occurred during drag and drop, you would end up corrupting cross-process OLE data transfers; the source application may think you're still trying to perform a drag and drop even though an error has occurred and the drag is not continuing.

How can I save .doc or .pdf file in sql database ???
Regards...
|
|
|
|

You can save them as the SQL Binary type if the data is less than 8000 bytes (8K). If you need to store files larger than 8kB, you could save them using the SQL Image type (which simply stores an array of bytes of length up to 2 billior or so). For more information on SQL datatypes, see MSDN's Sql data type table[^].
Once you've stored your pdf or doc files as bytes, you can then get them out of the database, write the bytes to a file, rename the file with the correct extension, and you're good to go.

Im new to using Xml with C#. I have been hacking around at one section for a day now and can't get it to work at all. Rather than confuse you with my shambles code, I will jsut explain the concept. Im also slightly confussed, or misslead with my understanding of the type deffinitions, and their methods for subtrees.
<br />
XML...<br />
<Root><br />
<MajorKey att="MAJattribute1"><br />
<MinorKey att="MINattribute1"><br />
<Value>value1</Value><br />
</MinorKey><br />
<MinorKey att="MINattribute2"><br />
<Value>value2</value><br />
</MinorKey><br />
</MajorKey><br />
<MajorKey att="MAJattribute2"><br />
<MinorKey att="MINattribute3"><br />
<Value>value3</Value><br />
</MinorKey><br />
<MinorKey att="MINattribute4"><br />
<Value>value4</value><br />
</MinorKey><br />
</MajorKey><br />
</Root><br />
Im having trouble getting it to create a nodelist to children underneath a node based on it's att (attribute) value. Also, I want to extract that attribute value into a string so "MAJattribute1" would gointo a string inside the loop for that node treversal.
Any help, or suggestions.
I have spent hours and hours reading, and cant seem to find anything to pinpoint this...only ever creating attributes indide a single node, not looping through based on the attribute value.
IM GETTING STRESSED
Regards

Edit your post, check Ignore HTML tags in this message (good for code snippets) and then we'll be able to see what you're talking about.
The w3schools site has good XPath tutorials, but I believe @ is used to indicate that you're specifying an attribute value.

I guess you mean the .net framework and not the sdk.
If so, take a look at 1 of these articles:
Visual Studio 2005
http://msdn.microsoft.com/msdnmag/issues/04/10/Bootstrapper/
Visual Studio 2003
http://msdn.microsoft.com/vstudio/downloads/tools/bootstrapper/
I'm in the high-fidelity first class traveling set.
And I think I need a Lear jet.

thank you very much spif,
I dont have much experience in Installers. If you are able to guide me clearly about how to install SDK in a quite mode wihtout any windows flickering will be helpful for me.
Anyway thank you very much for your immediate reponse.

You can use many installers, but my favourite is Inno Setup. It's free and even for commercial use.
If you're not familiar with installers, you can download also IS Tool, which creates your setup project using step wizard.
You'll have two items in the "Files" category there. The one is a directory (or just executable) of your app, and the second is the Framework SDK (marked as decompressed into {tmp} (temporary) directory, so its installer will be deleted after whole installation).
Now add this file in the "Install Run" category, so that it will be runned after installation of your app. If you want to install it before your application, you have to create a setup component.
To make the installation quiet, the SDK installer have to be runned with some parameter ("/q" I think).
Hope this helps.

Dear Itinka,
How to pass the command line arguement switches which supports the install.exe. From where to pass this command line arguements from the setup project. Only one window should be there which is a progress bar and all other installations should be done at the background without any clicks or user interaction. First it should install the .Net Framework 2.0, which will reflect in the progress bar, then it should start automatically the application and it should ececute and installed in the same manner by a single click. All the changes should reflect in the progress bar.
Can u please guide me on this requirement.
Regards
Mukilan.P.S
