hi,
i have a databound datagrid control in a winform. i need work arounds for some problems.
1. When i click the last row in the datagrid a new row is automatically added. i need to control this new row addition. Before adding a new row I need to check existing rows in the datagrid and validate against some criteria. Depending on the values existing in the datagrid I want to reject or accept the addition of the row. How can i do this. I tried onRowchanging event of the table the datagrid is bound to but got into some other problems.
2. How can i undo a latest edit made in a databound datagrid again based on some criteria.
3. I have included a combobox inside the datacolum and the combobox again includes a tree view inside. i got most of the job done but whenever i try to add a new row in the datagrid it adds up three new rows. Then when i click on the first of the newly added rows the other two disappear but when i click on the 2nd and 3rd i get the arrayindexoutofbounds exception. Any solutions for this?
hope I get some replies.
Thanks.

When I call StartService() Web Method of my Web Service, aspnet_wp.exe consumes around 100% cpu utilization. What is wrong with this?
[WebMethod]
public void StartService()
{
threadListener = new Thread(new ThreadStart(Listen));
threadListener.Start();
}
private void Listen()
{
//Some code for creating a init tcp listner
threadListener.Suspend();
}

Plz,
examine the memory consumption
using some tools. Tools such as System Monitor or Task Manager can isolate
those processes. When using System Monitor, if both the "Private Bytes"
counter and the ".NET # of Bytes in all Heaps" counter increase at the same
rate, this is evidence of managed memory consumption. Look at the size of
allocated managed memory and consider what the garbage collector is doing.
The allocation profiler might be helpful to you:

I want to make a browser likes IE, but .NET doesn't provide a web browser control ( I want something that I can configure it easily, not hard). Please help me.
|
|
|
|

The VS.NET Toolbox window can be customized to add ActiveX controls such as the web browser control. When you drop this control onto your form, interop libraries will be automatically built and used.
|
|
|
|
|
please tell me how to use that control( and what they are)!!!
|
|
|
|

Tutorial[^]. What this article does not say is that, instead of using the cmdline to extract what's known as interop libraries, you can let the VC#.NET IDE do it for you, by simply dragging the "Microsoft Web Browser control" COM component from the Toolbox to your Form.

I need to convert a string variable to an array of integers (An ASCII code for each character) and send it over to a Fortran code.
First, I have converted the string var. to an array of char (see below), but how can I convert this (kurt) to an array of integers?
string SetupPath;
char [] kurt;
int [] intFilePath;
.
.
.
kurt=SetupPath.ToCharArray();
intFilePath = ????

I create a Windows Service, I allow it to interact with the desktop and I can see the NotifyIcon in the try bar when the service start, but I can't use the Icon.
I explain better:
_I can see the icon
_I can see the tooltip
_I can see the baloon
_I can't see the Context menu when i click with the right mouse button
_I can't execute the action that I assign to the left mouse button.
So, the service can intercact with the desktop, but the user can't interact with the try Icon.
There is a solution?
Thanks for any help.
Regards,
Emanuele

The NotifyIcon only addresses the issue of the icon in the toolbar. In order for the user to interact with this icon, you have to create the context menu and click events for that menu.

If i run the app all run ok,
but if i do the same in a service there is that problem....

I have a problem with pointers in C#. In my code, i have to define a struct and one of the element of this struct is a string. But C# don't let us use a string in structs when we use it with pointer. So in struct i use "char". Then when assigning a char to pointer, c# only assigns the first character of the variable. As you see, i have to use a char array with pointers for this. But i couldn't that. Is anybody can tell me how can i do that?

Are you doing this for interop? If so, I suggest reading the "using win32 and other libraries from C#" column here:

Post your code, I'll give it a look.

Hi !
I want to read the text shown inside a word document to a string variable.
The problem is the normal appraoch
FileInfo f = new FileInfo(loadedPage);
StreamReader s = f.OpenText();
myvar = s.ToString();
which is used to read normal text files will not work with word.
Thanx !
|
|

|

 Sorry to disappoint you but a word document contains format codes. Open it up using note pad and a you will understand. You need to save it as a text file. In addition, if you save word in rtf, you can open it up using the rtf control provided by MS.
Hope this helps.

Hi !
I wont to call a flash exe inside a form I've created.
How can I do this.
(ps: I've heard there is a ocx that can be added but i dont know the name)
Thanx in advance
|
|
|
|
|
Is it an exe you want to call? if so just use
System.Diagnostics.Process.Start
if it's a swf file or a dcr (i think that's the director extension) then there are a couple of ocx's available
"Shockwave flash object" which is a file called flash.ocx and "Shockwave activex control" which is a file called SwDir.dll
depending on the type of movie you want to show, you should add these to your project and use as required.

-Bring the Toolbox Window, right-click and choose Customize Toolbox
-Select "Shockwave Flash Object" from the COM components tab. This will automagically build all interop libraries for the ActiveX control.
-Drop the control on your Form
-Depending on whether you want to dynamically set the .swf url or not :
-Static url : bring the Properties Window. On the top is a "Property pages" button. Set the url there. This will show the .swf movie at design-time.
-Dynamic url : once you have dropped the control, it creates a new member in your form, for instance axShockwaveFlash1. Just add this code : axShockwaveFlash1.Movie = "http://....swf";
