Guys,
I need help to create a windows service. The idea is that i have a webservice which would be serving a list of quotes. I want my webservice to fetch the updated list at regular intervals. The timing can be configured from a config file. I have tried using all the possible methods to do this bu none of them seem to request the list at regular intervals. I have tried using threads,system.threading.timer class and so on but my method is not fired using any of these methods.
In case you can help me just post me a sample windows service in VB.NET.
thanks.
Regards

That's not how a web service works.
But, in your post, you're not consistent when your talking about your service. Are you writing a Web Service or a Windows Service?
A web service supplies various classes and nethods for a client to call over HTTP. It doesn't run anything until a client calls it. It doesn't run like a Windows Service. You can't set a timer and have it execute code on a timer tick.

sorry for the typo it should have actually been a windows service which would fetch the quotes served by my webservice at regular intervals. Anyways i have already found a solution to the problem. thanx for replying.

I created a media player application in Vb.Net with mciSendString API. However, I am not able to retrive the song titles of the tracks on the CD. When I was using Windows XP's media player, I relaized that it was retrieving these hidden information and displaying the original song titles. Also, the media player is able to show the original CD Albume's picture. These information are hidden on the CD.
Do you know how can I retrieve these information (The original song titles, and the picture of the CD albume)?
If you help me, I would really appreciate it! Thanks!

No, it's not! Media Player retrieves this information from a database on the internet using a CD ID number, but I don't know how to retrieve it. I aldo don't know which CDDB database Microsoft is using.

Hi,
Could someone tell me how I could get Filesystemwatcher to monitor network drives? I have it monitoring local drives today but when I point it to a network drive does not seem to recognize any changes.
Thanks,
Zenly.

That depends on what kind of network drives you're talking about. It won't work on Samba (Linux) shares. Also, do not use this to monitor entire volumns. Response to events decreases with the number of directories (sub directories included) that your trying to track.

I'm trying to monitor a standard share on another windows machine. I even shared out a folder on the local machine and mapped to it and it fsw would not respond to changes on this either. I am running Windows xp sp2 and .nte framworks 1.1. Do you know if fsw changed any in VS.2005? I read a bit about it but I have not seen any major changes regarding fsw.
I'm just monitoring a few directories.

So long as the account that is running your app has the rights to see the files Modified date/time, it should work. There's nothing special to configure.
I don't know of anything that changed between versions.

Thanks Rage,
Yes... It was silly me. I did not use an id with enough privilege.

I am developing an application that gets streaming video from an ip camera and creates a set of .avi files. I need some way of compressing these individual files (hopefully from within my application) and then decompressing them for playback. Any suggestions?
|
|
|
|

Video is usually saved in compressed form. That, of course, depends on the graph that's building the .AVI file from the video source. But, for the most part, the file is already compressed, so trying to compress it again usually won't get you more than 1% reduction in size.

Ok, not sure exactly how to word this so here goes. I have a winform in my project that has the following:
Controls
1. DropDownList1 - Customer Name
2. TextBox1 - Customer ID
3. DropDownList2 - Site Name
DataBase Tables
1. tblCust - Fields(CustName, CustID, Status)
2. tblCustSiteAssoc - Fields(CustId, CustSiteID)
3. tblCustSite - Fields(CustSiteID, CustSiteName, ...)
What I am trying to do is this:
1. When the form open have customers names bound to the DropDownList1 control with nothing selected
2. Once I select something in the DropDownList1 control (SelectedIndexChanged) have it update the other two controls with the selected customers' data.
I assume I make a DataSet that queries all three tables and I understand how to bind the CustName to the first DropDownList box. What I don't understand is how to use the selected information to get the relevant information for the other two controls.
Thanks in advance,
Taen Karth

When you create your Dataset define a relation between all three tables. It may be better to do this back at the underlying database. Then bind all three controls to the DataSet as you normally would. Now when you select something from DropDownList1 the other two controls will display the proper related data.
I hope this helps.

Ok I think I need to break this down a little bit more for the relation:
Table1
CustID - PriKey - linked to Table2(CustID)
CustName
Status
Table2
CustID
CustSiteID
Table3
CustSiteID - PriKey - linked to Table2(CustSiteID)
CustSiteName
Addr1
Addr2
City
State
etc...
I have relationships setup like above. I created a new DataSet Item from Add New Item in IDE. Then it asks me to select Tables which I select the three above. It then adds these three tables to the designer with relationships and TableAdapters configured and all.
I then go to DropDownList1 and set the DataSource to the DataSet. It creates a binding source and then I set DisplayMember to CustName and it creates a new TableAdapter.
Now I want to select a customer name in DropDownList1 and have it filter DropDownList2 so that only SiteName shows that has a relationship between CustID and CustSiteID. I can only get DropDownList2 to list all SiteName. I can't figure out how to filter it.
Thanks,
Taen Karth

To filter use a DataView. You could say something like this:
DropDownList2.DataSource = DataSet.Table3.DefaultView
DropDownList2.DisplayMember = "CustSiteName"
But, since you have the tables related to each other I don't think filtering is neccessary. Instead set it up like this:
DropDownList2.DataSource = DataSet.Table3
DropDownList2.DisplayMember = "CustSiteName"
Since Table3 is in a relation it will show the proper records in DropDownList2
Also, I think you could elliminate Table2 and have CustID in Table3.

Is it possible to insert a web address in a console project as a hyperlink, and if so, how? I have a function to return a concatenated string as a complete link, but I have found no info as to whether or not it can be active.

As a console application just reads and writes to the Standard In, Standard Out and Standard Error streams it is up to the container (normally the command prompt) to activate links.

While I can change the text which appears in the title bar on my Windows forms, is it possible to change the Font property too?
|
|
|
|
|
Not easily. You have to override WndProc and supply the code to draw the non-client area of your form yourself.
The title bars use the systems Display control panel properties, following the theme picked by the user.

I am quoting a clear example of the Junction table, in Northwind sample database.
When employing this database in a DataGrid, I receive DataConstraint Exception Error in the Junction table "Order Details" or in the "Orders" table, with the following error message:
"Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints."
On displaying one of the errant tables, each row complains as below:
"ForeignKeyConstraint, Shipper_Order (for example) requires the child key values ????? to exist in the parent table.
NOTES:
1- I established Relations just according to the ones in MS Access application.
2- The Same Database is Functioning normally inside MS Access application.
3- I am mainly concerned about the Junction table.
I need professional guidance as this is a study project, I am working on.
