Use a different converter - this code is very simple to convert.
In VB, you can specify an event combined with an implicit delegate.
The conversion to C# (via Instant C#) is:
public delegate void ClassErrorEventHandler(ClassErrorData e, bool CriticalError, bool MustDisplay);
public event ClassErrorEventHandler ClassError;
(the formerly implicit delegate has been named 'ClassErrorEventHandler' in the conversion).

Is there a way to (check/scan through network) ip addresses of listening ports in a network
|
|
|
|
|
Probably you have to connect to it, if you get an exception -> port closed, otherwise successfull, then close it.
|
|
|
|
|
If you put the server listining you will(or not) accept clients and by that get their ip.
Having the ip´s send whatever package you want to.
I assume that you didn´t start yet. Download some application here and see the code, if you have doubts ask here then.

I am new to .NET interoperability. I need to write some C++ code which would access the methods of a .NET component. Any help is greatly appreciated.

I am developing a project in which , application will search all the computers in a network, ranging from 100-10000 and then write all the software's installed in every machine in a single text file.
please suggest me
1)Is it feasible to create a thread for every machine an d in that thread i would search the machine details.
2)Do a serial search 1 by 1.
3. or create a limited number of threads say 25 for first 25 machines then, wait if any thread is available , if a thread is available then allot it new machine.
which option is best and more fast...........
|
|
|
|
|
I'd go with 3rd one. It's more efficient as you are re-using threads.
|
|
|
|
|
That depends a little on what you mean by "best", and somewhat on the hardware.
Option one is not practical with the number of threads that you specified.
Option two would work well as a long running background process, as it doesn't hog the computer or the network.
Option three is fastest. The optimal number of threads is difficult to predict, though. Make it configurable, so that you can try some different settings.
Despite everything, the person most likely to be fooling you next is yourself.

hi all,
i filter a datagrid with respect to a texbox input. It filters fine. But how do i bring back the original data into the grid when the textbox is empty?
code below:
<br />
if (txtQS.Text.Trim != "") {<br />
TMSDataSet.LASTIDNOREFFDataTable dt = new TMSDataSet.LASTIDNOREFFDataTable();<br />
LASTIDNOREFFTableAdapter.Fill(dt);<br />
DataView dv = new DataView(dt);<br />
dv.RowFilter = "lastmonth = " + txtQS.Text;<br />
LASTIDNOREFFDataGridView.DataSource = dv;<br />
LASTIDNOREFFDataGridView.Refresh();<br />
}<br />
else <br />
LASTIDNOREFFTableAdapter.Fill(TMSDataSet.LASTIDNOREFF);<br />
Thanx.
He who goes for revenge must first dig two graves.

Have you tried clearing the filter? You might want to check if the textbox where the filter criteria being written is empty, you might want to clear the RowFilter property.
|

Hi,
My advice is simply, do it with SQL store procedures.
Don´t filter, sort, edit in c#. Do the store procedures and trigger then in c#, with whatever event you want button_click, form_load etc.
It´s very easy
If you have doubts ask here how to make them(SP).
Good Luck

Not sure what this is called exactly. I am after creating a method or class you can pass variables to. I want to be able to give them a pre-set list of what variables they can pass e.g. "txtOutcomes.TextMode = " automatically brings up "TextBoxMode", where you can select ".MultiLine;". Hope this makes sense. Many thanks.

Its not very clear what you are trying to achieve, but I'm fairly certain you are going to be way out of your depth.

its called an enum, you define one as follows:
public enum MyEnumeratedValues
{
MyValue1,
MyValue2,
MyValue3
}
You can then have a property of this type on your class
public class MyClass
{
private MyEnumeratedValues aProperty;
public MyEnumeratedValues AProperty
{
get{ return aProperty; }
set{ aProperty = value; }
}
}
now when somebody creates an instance of your class and sets the AProperty property, intellisense will show them the 3 values defined.
I think thats what you're after

Fantastic! That's loads of help. Many thanks.

I have populated a treeview (tvwResults) with some data such as:
item1
subitemA1
subitemB1
item2
subitemA2
subitemB2
subitemB3
subitemB4
item3
subitemA3
...
...
...
I have added an imagelist control with three images with indexes 0, 1, 2
for error, fail, warning
I am tying to assign the correct image to each item and subitem accordingly...
For example, if there is an error in one of the subitems, then that subitem will have the image of error which is index 0 and so the image for that item i.e. the item will be warning i.e. index 2
And if all the subitems of an item have fail in the text then the image for the item will be error too.
I have started working on the following code.
Question:
can you please see if what i am trying to do in this code is correct based on the above request?
Thanks
foreach (TreeNode n in tvwResults.Nodes[0].Nodes)
{
foreach (TreeNodeCollection nc in tvwResults.Nodes[0].Nodes)
{
if (nc.ToString().ToLower().Contains("error"))
{
nc.ImageIndex = 0 // error...
????
}
}
}
|
|
|
|
|
Put your image in ImageList.
Then use : nc.StateImageIndex = 0; // or 1, or 2, ...

If I resizes/increases the size of a column, then grid should show scroll bars instead of reducing size of other columns?
How should i do it?

Hello everyone,
I am developing an Http client which could collect data from external web sites. Currently, I want to test with the web sites which needs certificate to access (either needs client to accept its certificate or needs client to provide client's certificate).
I am suffering from finding a number of such web sites, could anyone provide some such types of web sites please?
(most web site I investigated are using ActiveX control to provide secure access, not using certificate)
thanks in advance,
George
