ProgressBar on long processes

1-Aug-04 20:24

ASP.NET is compiled. This is most obvious if you are using code behind files. If you are embedding C# code into the aspx pages then the first time the page is encountered .NET will compile the C# in to an assembly and this may look as if it is interpreted if you get the errors "one by one" as you navigate through your site - however it is all compiled on the fly and a second visit to the same page will not trigger the compilation process unless the ASP.NET process realises that the aspx page has changed.

Alternatively, you could just be seeing normal runtime errors. However, as you say "when i build my project i get the error one by one" that suggests that you are getting compile time errors, but every time you correct one it unhides another.

If you need more help then you need to explain how you've built your application and what errors you are getting and exactly where they are occurring.

Can't manage to P/Invoke that Win32 API in .NET? Why not do interop the wiki way!

Your question would be better handled in the Embedded/Mobile Forum.

I'm not too sure how to say what I would like consisely but here goes:

If my program is doing a somewhat cpu intensive process, I would like a threaded progressbar to come up, and give an intication of how long the process will take, then once finished hide itself again and the program continues. I can make the progressbar already, as well as thread it.

All I want to know is how to invoke it. ie how to find out if the process I'm running warrants the bar or not. Any ideas?

That would depend on the process your running, and would normally be determined by the process, not the part that launched it.

The process would have to be able to determine the amount of data that must be processed AND track where it is currently. For example, searching through an unknown number of files would not lend itself to a progress bar because you can't determine when the progress is going to end. But searching through a known number of files will. All you have to do is keep track of the number of files you've searched through.

The process would also have to implement a timer where if the process is still running after say, 3 seconds, the timer would set a flag that shows a dialog with the current progress information. This progress tracking would be running regardless if the dialog was showing or not. The timer is only there to flip on the display of the progress, not to start it.

If you're trying to track the progress of a component you didn't right, there is not much you can do to implement the progress bar. Your component must be able to tell you how much processing must be done and how far along it's gotten. It must also be able to fire off events on some condition that lets you know progress is being made. If you component doesn't give you any kind of information like this, your SOL.

Problems binding a dataset to a combobox

I just can't seam to figure out why the following code is not working. I would be thankful for any help.

Thanks,

JefferyS
Frown | :(

CODE:
string folderPath = "C:\\My Documents\\Visual Studio Projects\\MyDroidEngineer\\Data\\";
DataSet myDS = new DataSet();
myDS.ReadXml(folderPath + "planets.xml");

cboPlanets.DataSource = myDS.Tables["planet"];
cboPlanets.DisplayMember = "description";
cboPlanets.ValueMember = "swgcraft_id";

I get no errors and just a blank combo box
I have used a temp datagrid to check the dataset and it displays correctly.

Top Part of XML File:

<planet_data>
<planet swgcraft_id="1">
<description>Corellia

<planet swgcraft_id="2">
<description>Dantooine

<planet swgcraft_id="3">
<description>Dathomir

Only thing I can suggest you with the code && info you gave is to try with:

//
cboPlanets.DataSource = myDS;
cboPlanets.DisplayMember = "planet.description";
cboPlanets.ValueMember = "planet.swgcraft_id";
//

Instead of what you wrote for those tree lines. If that doesn't solve drop solution somewhere and give link or give more info Wink | ;)

I have seen the problem and hope following would work

cboPlanet.DataSource=DS.Tables[0];
cmboPlanet.DisplayMember="description";

in place of the table name put its index no here (0).

I think you need to call DataBind() method of the combobox after setting the properties.

ToolTip Control in pocket pc.

Thanks for all the suggestions. I figured out what was wrong and it wasn't the code. You can't set the sorted property on the combobox to true when using a dataset.

I don't know why it didn't give me an exception error.

I hope my folly helps someone not spend hours and hours trying to figure out why it was not working.

Thanks again for all the help.

Thanks,

You can't.

Tooltips are not supported on the Pocket PC. If you think about it: How would they be activated? There is no mouse pointer to hover over controls, is there?

I tried, but at 1 cm, no reaction. So I tried hovering the stylus at about half a centimetre but still nothing. So I tried at about 1mm but I was not steady enough and hit the button by accident. Blush | :O

Well Pocket Word for example supports tooltips. To bring up a tooltip I think you Tap-and-Hold the button. It should not bring up the Tap-and-Hold menu but instead it brings up a tooltip.
