hi All,
me and my friends are trying to make a Docklet application for windows and i am not sure of the things to learn to be able to start codding the application,
so if anybody can help us and tell us the things to learn to be able to make our application come true.
i know that there exist already docklets apps for windows but i want to make my own :> so if any body hava a clue of what to do please tell me.
till now all i know is i need C++ and we are good at, and OpenGL which we are going to learn.
thanks all and Best Regards.

no that's not the DOCKlet in mean, what i am talking about is a windows application that look like the system tray that has shortcuts to your favorite apps like the one in the MAC OS.
i didnt mean the java doclet.

So are you saying you just made that up? Don't do that, don't make up your own terminology. No one will have freakin clue what you are talking about. Can you doclet that?

I have no idea what the thing in the MAC OS is that you mentioned but what would OpenGL have to do with displaying shortcuts in a system tray? 
And finally, this is the "Windows Forms" forum. That means System.Windows.Forms which is a namespace in the .NET Base Class Library. For questions working with Native Windows development you want to use the Visual C++/MFC forum. But be warned, if you don't use standard Windows programming terms it is unlikely anyone will figure out what you are talking about.

hey google it and you will find it and some apps already done that

Hey I see you fixed the misspelled Doclet in the subject of your first post but see how it shows up in the replies anyway? That's sort of like a Docklet hu? And that's why I did find anything but a Java reference when I googled "doclet" instead of "Docklet". Like did you notice how the C++ compiler produces an error when you omit those semicolons? 
So basically you want to create a Windows Application that has similar features to this ObjectDock application? Go to the Visual C++/MFC forum and read the first post in the forum titled "How to get an answer to your question", pay attention to item #2.
See you around.

I suggest you break point these lines then find out which one is the problem, and what is null. We can't possibly solve it for you better than that. Once you know the line, we can make suggestions, obviously.
F9 sets a breakpoint, then F5 starts debugging.

Hi All,
I am facing One Deployment Problem,
My Project Architecture is Presentation Layer Communicates with Web Services and Web Services Communicates with Data Acess Layer and DAL Communicates with Data Base.How to Deploy These Layers Individuly and Give the Connection while Installing.
Thanks
|
|
|
|
|
Why would you deploy them individually ? What use is the web service without the presentation layer ? I assume the DAL is not deployed ? If it is, of what use is a web service ?

Thanks Christian Graus,
BUT,
Reason for Deploy Individully is,Clients are at One location (ex : Location 1),Web Services are at Web Server(ex: Location 2) and DAL,DataBase at DB Server(ex: Location 3).
Is this Correct approach to Proceed? Can u give me suitable Solution for this.
Thanks,

see the bellow code which i have
const url = "E:\\ThunderBirdApplication\\Application.exe" "%1"
var uri = Components .classes["@mozilla.org/network/simple-uri;1"] .getService(Components.interfaces.nsIURI)
uri.spec = url
Components .classes["@mozilla.org/uriloader/external-protocol-service;1"] .getService(Components.interfaces.nsIExternalProtocolService) .loadUrl(uri)
if it is correct the above code to pass parameter then, how to call those parameters from windows application(Application.exe)
|

They are passed in to the main method of the app as a collection.

Hi,
I have a DataGridView on a window form. I want to implement a functionality where user can edit any of the record in the DataGridView & click on Edit button. When the Edit button is clicked, the record should be updated in the database.
Also, I want user to add new records to the DataGridView from the data entry screen.
Can any one please help me on both? I don't have any code written for the same so not posting it here.
Thanks,
HR

Hi,
Please try the following code snippet to update Grid and underlying database simultaneously.
BEGIN CODE
dgv1.Update()
ds1.AcceptChange()
dgv1.Refresh()
END CODE
Regadirding the other issue I would suggest you to take a look at following sample. It show how we can show a newly added row (via Form) in DataGradView and other ADO.Net features.

Hope this helps  .

Dear Sir,
1.we are developing one project. in that we are using "CODEC"
com object for video recording & displaying.
2.Coder records the video. Decoder Disply the video.
3.We used Windows Media Encoder 9 series SDK.
4.we used WME-Interfaces(we used WMEncoder & IWMensouce Interfaces,... )
for recordig video,displying video etc....
5.In this i have option to merge the existing videoo with recording video.
6.i can merge video or images to the recording video.
7.FOR RECORDING WE ARE USING " WINDOWS MEDIA VIDEO 8 FOR LOCAL AREA NETWORK
384 kbps
8.FOR MERGING WE ARE USING " WINDOWS MEDIA VIDEO 8 FOR LOCAL AREA NETWORK
256 kbps.
9. afetr merging the video we can see the whole video in the preview.
10. THE PROBLEM we facing is: in the preview recorded video is disply
clearly, but that inserted video, which we insert to merge with the recording
video, has not diplyed clearly.
11. blurring occrs in the inserted video.
12 we find this blurring clearly in the previewing the whole video.
Expecting from you:
please try to help me, what should i do, to avoid the blurring.

Sounds like you're using a third party control and should be talking to them.

Hi,
I am currently working on a demo winforms project which has DataGridView control. I have hardcoded the data (using string arrays) & populated in the DataGridView control.
The DataGridView has first column that contains checkbox.
For deleting, I have taken button control & user needs to check the checkboxes to select the rows & then press delete button.
I have found that when first two rows are selected & then delete button is pressed, only first row gets deleted. Also, I am not able to delete any two consecutive rows properly.
I think when a row is deleted, the index of the remaining rows gets changed & this seems to be the problem. But I am not able to find any solution for the same.
Can any one help me for the same? The code for delete button click is as follows:
<code> private void btnDelete_Click(object sender, EventArgs e)
{
int rowCount = 0;
for (int counter = 0; counter < dgDemoGrid.Rows.Count; counter++)
{
if ((bool)dgDemoGrid.Rows[counter].Cells["colSelect"].FormattedValue)
{
rowCount++;
}
}
if (rowCount > 0)
{
DialogResult response = MessageBox.Show("Are you sure you want to delete selected row(s)?",
"Confirm Delete", MessageBoxButtons.YesNo, MessageBoxIcon.Question,
MessageBoxDefaultButton.Button2);
if (response == DialogResult.Yes)
{
for (int counter = 0; counter < dgDemoGrid.Rows.Count; counter++)
{
if ((bool)dgDemoGrid.Rows[counter].Cells["colSelect"].FormattedValue)
{
dgDemoGrid.Rows.Remove(dgDemoGrid.Rows[counter]);
}
}
}
}
else
{
MessageBox.Show("Please select row(s) to delete", "Delete Row(s)", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
</code>

Change your counter to go backwards when doing the remove, then the relative position remains the same, i.e. don't start at zero and add, start at dgDemoGrid.Rows.Count and subtract.
