Did you read this? All I can tell from whatever you've told is that you're not instantiating an object where you should be.

I had instanciated it. However, still its remain same. Kindly, provide better remedy
|
|
|
|
|
With the information that you've provided, that's just not possible. How did you create this wrapper??
|
|
|
|
|
I had created Wrapper from Dotnet by using tlbimp. I used this command to create Wrapper from command prompt of Dotnet. The command is "tlbimp <vc++dll file="" location=""> / out: <rcw class="" location="" where="" you="" want="" to="" create="" it=""> /verdose"
If you execute this command, this would create RCW class for specified VC++ dll. Why did I created it in worng way? Is it so, Kindly provide betterment of it.

That's doing it the hard way, but it works. Is this a COM-based .DLL (registered using REGSVR32) or a library .DLL??
COM-based .DLL's you can add a reference to and Visual Studio will automatically generate the wrapper for you, without using the command line to do it.

i created a datagrid with two columns(employee name,designation). If user select rows and if selected row contains employee name="aaaa" then don't delete that row and other rows can be deleted.
my code goes like this, initially i done dataview.AllowDelete=false to stop deletion.
private void dataGrid1_KeyDown(object sender, KeyEventArgs e)
{
if(e.KeyData.ToString()=="Delete")
{
for(int i=0;i<dv.Table.Rows.Count;i++) //dv is dataview
{
if(((DataGrid)sender).IsSelected(i))
{
if(!(((DataGrid)sender)[0,i].ToString()=="aaaa"))
{
dv.AllowDelete=true;
dv.Delete(i);
datagrid.DataSource=dv;
dv.AllowDelete=false;
} } } } }
using this code when rows are selected and delete key is pressed first last column value get deleted not whole row.

Your server won't send the message, you code is working. Lookup relaying and you'll see what the problem is. You must use a domain that the exchange server recognizes, unless it is open relay(which is bad).

When I open Previous project,IDE notify :
“Application procedures required for the project(xxx.csproj) are not installed.
Has been installed to ensure that the project types (. Csproj) applications.”
I created it in XP with VS05 ago.
Now I open it in Server2003 with VS08.
What is the reason?
Thanks.

Hi,
Ive been trying to add a trackbar to the property grid form element in c#.
Unfortanely i only find you can draw pre defined controls with
UIType Editor and Control Paint. (Checkboxes, border style and little more).
Does anybody have some feeling about if this is possible? To draw a trackbar
on a property grid?
Thank u

Hi,
You are correct. The Microsoft PropertyGrid only allows a simple textbox, a textbox + button, or a textbox + dropdown button as inplace editors. Therefore you have 2 solutions:
1. Either host your trackbar in the dropdown window appearing when you click the dropdown button. You will need a UITypeEditor for that.
2. Or use a third party PropertyGrid like Smart PropertyGrid which allows many more types of inplace controls, the trackbar being one of them.

wat could be the problem here??any help will be highly appreciated

i think that you have the focus on that button and if so the tooltip doesn't appears anymore.
Try to remove the focus form the button maybe it works.

Hi raj,
My suggestion is you may add a mouse hover event on that button.When move over the button then fire event to show up what you want to display.
example,
public ToolTip tooltip=new ToolTip();<br />
public Form1()<br />
{<br />
InitializeComponent();<br />
button1.MouseHover += new EventHandler(showTooltips);<br />
}<br />
<br />
private void showTooltips(object sender, EventArgs e)<br />
{<br />
tooltip.ShowAlways = true;<br />
tooltip.SetToolTip((Button)sender, "50");<br />
}
from the example, when you click on button,it will display '50'
Hope this help you.
regard
