Is is possible that the target file has already been opened (for exclusive read or write), thereby preventing it from being overwritten? Although I think if that were the case you'd see a different exception.

Sorry, I have no solution for you. Just a question: Why don't you use WebClient.DownloadFile for downloading the image?
Anyway, your code seems to be correct...
P.S. Have you heard about Path.Combine (because
+"\\" doesn't look so good)

Hi,
i have gridview and have Detail View.
I want to edit the page with all controls loaded instead of showing in Bound Field.
While using <asp:CommandField ShowEditButton="True" />
i am able to show all values in Text boxes.
Instead i need to show in respective controls like textbox,checkboxlist,listbox and drop down.How to implement this?
Any urls or links?

This is my code
if (sender is ContextMenuStrip)<br />
{<br />
foreach (ContextMenuStrip item in (((ContextMenuStrip)sender).GetCurrentParent().Items))<br />
{<br />
if (item == sender) item.Checked = true;<br />
if ((item != null) && (item != sender))<br />
{<br />
item.Checked = false;<br />
}<br />
}<br />
}
This is my error
Error 1 'System.Windows.Forms.ContextMenuStrip' does not contain a definition for 'GetCurrentParent' and no extension method 'GetCurrentParent' accepting a first argument of type 'System.Windows.Forms.ContextMenuStrip' could be found (are you missing a using directive or an assembly reference?) C:\Users\Kyle\documents\visual studio 2010\Projects\Gadgets\Gadgets\Form1.cs 341 75 Gadgets
Can some please help me fix this?

So where did you get the GetCurrentParent from, make it up or snaffle it from someone elses code? The error means that there is no supporting method.
Never underestimate the power of human stupidity

Couple of things:
1. GetCurrentParent isn't a member of ContextMenuStrip
2. A context Menu item will arrive as a ToolStripDropDownItem and you will need to drill down from there to get the items you want...
Try this:
foreach (ToolStripMenuItem item in ((ToolStripDropDownItem)sender).Owner.Items)
{
if (item == sender)
item.Checked = true;
else
item.Checked = false;
}
|
|
|
|
|
Well the error I get with this is
Unable to cast object of type 'System.Windows.Forms.ToolStripSeparator' to type 'System.Windows.Forms.ToolStripMenuItem'.
So I would need to make it not notice the separator, what do you suggest?
|
|
|
|
|
Yes I would suggest ignoring any of the spearators, as you don't need to set teh check state of these...
|
|
|
|
|
ok, Is this a good way to approach this problem?
foreach (ToolStripMenuItem item in ((ToolStripSeparator)sender).Owner.Items)
{
}
|
|
|
|
|
No a better approach would be to:
foreach (ToolStripItem item in ((ToolStripDropDownItem)sender).Owner.Items)
{
if (item.GetType() == typeof(ToolStripMenuItem))
{
if (item == sender)
((ToolStripMenuItem)item).Checked = true;
else
((ToolStripMenuItem)item).Checked = false;
}
}
testing for the items type before you set teh check state of an item.

Thats way better but its bad because it overflows
An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll
|
|
|
|
|
really, the example I'm using here doesn't. I have a context menu with 3 menu items 1 separator 1 dropdown list and 1 test box ... and it seems to set the check state correctly...
Is your code a complete copy or my or have you just instered the elements you need?
I also assume that you are using this kind of approcah as you have multiple context menues and multiple menu options and only wish to have one function to do the work?
|
|
|
|
|
I put that code in and not edited it
|
|
|
|
|
ok, the only reason that you'd be getting a stack overflow from this loop is if new menu items were being added to the context menu strip, so in effect you'd be getting an ever increasing list.
That's something to check also to make sure that during each iterration of the loop that the count list count doesn't change.
As I said the example snippet I have here doesn't exhibit that issue....
Aslo as I mentioned earlier you can directly access the menu items and context menu required without looping round, for example:
myToolstripMenuItem1.Checked = true;
myToolstripMenuItem2.Checked = false;
myToolstripMenuItem3.Checked = false;
foreach (ToolStripMenuItem item in myContextMenuStrip.Items)
{
.......
}

I still don't know how to fix this over flow problem
|
|
|
|
|
As I mentioned something must be adding more ToolStripMneuItems to the ContextMenuStrip.Items collection.
Are you adding context menu items programmatically?
|
|
|
|
|
No I just made the strips as I did like, heres a example in visual mode
Strip1
Strip2
Strip2
Strip4
separator
Strip5
