SPend money to replace your timerware demo with a normal license.

one way to make it work is by unistalling it then cleaning up your registry manually.then reinstall it. however, like Dan said, you can spend money and buy the license.

Call to Web Service using HTTP GET does NOT work

Hi,

I hope this is the correct newsgroup for this question.

I am creating a test web service that I wish to extend.

The example I am working from suggests that Web Services can be called direct using HTTP GET, eg:

http://server/webServiceName.asmx/functionName?parameter=parameterValue

However when I try this I get the following error:

Request format is unrecognized for URL unexpectedly ending in '/functionName'.

It works fine if I first call the service, click on the public method and then invoke.

I am using IIS5.1, VisualStudio2005 and .NET 2.0

What am I doing wrong? (I even tried altering the IIS settings without success)

Thanks in advance

Andrew

Have you tried this below?

Hi,

Yes, however this acts as though I have missed off the

?parameter=parameterValue section.

ie: It returns the usual page listing all the public methods for the web service as though I had used the basic URL: http://server/webServiceName.asmx

Any other suggestions/options?

Thanks Andrew

The subject is really too involved to go into in a forum post. The best source I know of is 'Programming Server-Side Applications for Windows' by Jeffrey Richter and Jason D. Clark (Microsoft Press), but unfortunately I believe it's out of print.

anti-aliasing images in GDI+?

Hi all

Is it possible to anti-alias the edges of a rotated image using GDI+/.Net 2.0? I am rendering an image onto another and because it's rotated it'll have jaggies. I know that you can use InterpolationModes and SmoothingModes but it doesn't seem to affect the edges of the image against the background image.

Any pointers?
Thanks

I don't think so. But you could adjust the alpha values of 'all pixels at the edges' prior to call DrawImage. Probably this helps a bit...

DataGridView selection on right click

I have a DataGridView object and I added a ContextMenuStrip control to the DataGridView.ContextMenu. This works well, if I right-click the datagrid view I get the context menu I wanted. The problem is, I would like to, just before the context menu appears perform a left click to also select the cell or row under the mouse at that moment. Not sure what is the best way to do this.

Thanks.

Hi, Johnny. This CellMouseDown event handler should work:

private void dataGridView_CellMouseDown(object sender, DataGridViewCellMouseEventArgs e)
{
    if ((e.RowIndex >= 0) && (e.ColumnIndex >= 0))
    {
        dataGridView.Rows[e.RowIndex].Cells[e.ColumnIndex].Selected = true;
    }
}

Activating Client side Web Service from Browser - HELP

Andrew Mercer25-Jul-06 6:05

Andrew Mercer

25-Jul-06 6:05

Hi,

Scenario:

1. User opens browser on their laptop/desktop.

2. User connects to remote web application.

3. User browses and clicks required button on web application.

4. As a result of clicking the button the web application activates/calls a web service on the client machine.

5. The web service then makes call back to web application and downloads the required data.

No data is delivered to the client ALL that happens is the action in (4) that allows a method to be called in the client and then the data is requested after necessary security checks.

Note: The desktop/laptop will always have .NET Framework installed. The call to the web service will always be to the current desktop/laptop.

Is the above possible? If not is there any suggestions as to a possible solution.

Thanks in advance.

Andrew

P.S I have done what I require with all the actions being driven by actions/calls from the client standalone windows application.

Certificate in .Net

I'm working with a smart card and need to get the certificates in to the store. I don't know much about certificates but I think it's something wrong with the root-certificate. When I add it, it won't show up in the certificate list in IE. I get this fault message when I run the program:

Unhandled Exception: Microsoft.Web.Services2.Security.SecurityFault: The securit
y token could not be authenticated or authorized ---> System.Security.SecurityEx
ception: WSE537: The certificate's trust chain could not be verified with the fo
llowing reason: Ett internt certifikatkedjningsfel har inträffat.

Ett internt certifikatkedjningsfel har inträffat. = An Internal certification chain fault has occured.

I have search a lot on the internet but can find any thing about this.
Can any one help me or does any one know a good book about certificates in .Net?

Timespan for Timer-interval

Hi
Is there any way I could use a TimeSpan as a interval for a Timer? milliseconds doesnt quite cover it when dealing with large intervals.

What I am making is a way for the application to get an event every day at the stroke of midnight. The code I use now is here:

This is for starting the timer with a interval that make is trigger on the exact hour of midnight.

DateTime now = DateTime.Now.AddDays(1);<br />
DateTime time2 = new DateTime(now.Year, now.Month, now.Day, 0, 0, 0);<br />
TimeSpan dif = time2 - DateTime.Now;<br />
<br />
timer1.Interval = (int)dif.TotalMilliseconds;<br />
timer1.Enabled = true;

If anyone know a more elegant way of doing this then PLEASE let me know. At least I want to get rid of the millisecond interval as a whole day is something more suited for TimeSpan object.

The Today property contains the current date at midnight.

TimeSpan dif = DateTime.Today.AddDays(1).Subtract(DateTime.Now);

What if I want it to happen at every hour instead of every day then?

interop & performance

I have an application which use has a DLL with 100+ (auto-generated) Managed C++ wrapper around some native API.

Compare to a purely version my application has some performance issue and I just realized it is probably due to the security check which happen just before each of the (numerous) call into this native API.

Now I know that, perhaps, I could tag my MC++ wrapper with
<suppressunmanagedcodesecurityattribute>

But I wonder if there is not an other call I could place in the Main() function (such as Permission.Demand() or stuff like that) which will achieve the same result?

After all my code this is for a desktop application with as much right as the user.

24-Jul-06 19:07

Hi All,

My task with combobox is:
When I Type a letter in combobox it should select the Item which is starting
with the letter.
for example the Combobox items are One,two,three,Four,Five,thirty,forty,fifty etc.
When I type 't',it should select "three" which is first in combobox items and the focus on remaining "hree".agian when i type 'h'(becomes"th") and the focus on "ree",on typing 'i'(becomes"thi"),combo should select "thirty",and focus on "rty".like that it should go on.

Please suggest.
Thanks In advance

Set the AutoCompleteSource property of the ComboBox to ListItems (if in .NET 2)

If you're using .NET 1.x then you'll need to write or use a combo box which supports autocomplete. There are a few articles on this site regarding this.
