I am a student, and we have a project about making a computerized system.
I am making the data entry module of the grades per class. How can view in the datagrid all of the students who enrolled in that class.
I hope you understand me...
please reply as soon as possible.

Really ? Here in the VB.NET forum ? Seriously, try putting a meaningful subject line.

By doing a SQL call to get that data, and putting it in a control like a gridview. What is your data store ?

See, that's just rude.

ok, sorry, its my first time here...
i just made database in access, the database is composed of different tables: file maintenance of the students, then the different subjects...
how to do an sql call to get the data???
in my module, the user will need to click the search button to search for the the different subjects. then, if you click it, all of the students who enrolled in that subjects will be view in the datagrid...
how can i do it?? i made a separate database for that. I think, i need to make a query for that, but i dont know how.

There are classes built into .NET for database access, there's tons of info on the web, google 'VB.NET Access database'. If you don't know how to write the SQL, then you need to buy a book and work through it, you're after the most simple SQL line there is.
Rharzkie wrote: I think, i need to make a query for that, but i dont know how.
Yes, you need to take the string and pass it to a query that searches for it. Again, you're asking very much beginner SQL questions, you need to buy a book and learn from it, so you have some understanding of what you're trying to do.

i just wanna ask again, about what i posted last night... I made a 3 database in access, then how can I connect those 3 database to each other.
I'd use the OleDbDataAdapter. In the data adapter configuration wizard, in the query builder, will i choose those 3 database so that it will be connected?

As already stated, it's important to read the forum guidelines. We have had a ton of 'bad posts' lately. Some of the highlights:
1. Don't use words like 'need help' or 'urgent' in your message titles. Give them meaningful titles like 'having trouble connecting to DB' or whatever.
2. It makes it easier for us to help you if you post some of your code so we can see what you have, where you are going wrong/right, etc.

Hi,
I have a schema which reflects a table in the database.
I've just added a field to the schema table, called Watermark.
I've built the library.
But when I access it in my main project, the intellisense works:
reportSchema.Dataset.tblReport(recordnum).Watermark
But at runtime, I get an error:
Watermark is not a member of tblReportRow
I've tried removing and readding it a few times.
Its like the autogen code in vs2005 hasnt updated everything.
Anyone seen this before?

Did you just add this field to the database only?? The designer will not know this happened and hence, won't regenerate the code you're talking about. You either have to scrap your existing dataset and drag the table to the desginer again, or you have to modify the designer generated code by hand to add this field and all the support for it.

is there any program that finalize the application of vb2005 in order to launch in any computer ?

Visual Studio includes a setup project type - Add that to your solution.

Well since it appears that Google is down where he lives I at least took the time (for some odd reason) and did a Google Search[^] for him.
magedhv,
Hopefully Google will be up and running in your area again soon.

Hi
Is can you not add a reference to ppt object then open it up from there (it is a COM object):
http://msdn2.microsoft.com/en-us/library/aa220907(office.11).aspx
to create the application. Then use this resource to get the desired effects:
http://msdn2.microsoft.com/en-us/library/aa213568(office.11).aspx
This provides a complete overview of the power point object model so you can use its functionality to get what you want.
I am sure there will be an activex control but I have only ever done it this way so can only offer this help.
Hope it is of use

Is any other Way?

If you're not willing to do it the way that has been suggested, then I'd recommend black magic, it's as likely to work as anything else, once you've excluded the right way of doing things.

Hi,
I am using an SQLDataadapter in my app, with a query. Something along the lines of:
SELECT * FROM MyTable WHERE MyTable.MyField IN ('ABC', 'DEF', 'GHI')
The number of items in the IN bit is variable as well as their respective values.
Usually with a parameterized query I would use @MyParameter in the query and then
SDA_MyAdapter.SelectCommand.Parameters("@MyParameter").Value = "ABC"
This doesn't work however when I try:
SDA_MyAdapter.SelectCommand.Parameters("@MyParameter").Value = "ABC, DEF, GHI"
Can I use this principle at all in this case, and if yes, then how?
If not, then how else can I do it using good VB.NET practices?
All help and suggestions appreciated,
Johan

Not sure, but is the problem occurring in any other test cases, such as ones without the , being used...

Hi Paul,
I have tried the following variants:
- "ABC,DEF,GHI"
- "ABC, DEF, GHI"
- "'ABC','DEF','GHI'"
- "'ABC', 'DEF', 'GHI'"
In all cases the hard coded query will return results but not the parameterized one.
How would you propose to do it without commas?
Best Regards,
Johan

Hi,
I have coded a small desktop based windows app which parses a flat text file and generate a word document with some values from the said file. The code contains lots of loops and huge string manipulation and its 438 lines of code. The problem is when I checked task manager, its eating memory worth 20MB !!
So, any ideas, suggestions, checklists in this situation how to decrese occupied memory by the program from string manipulation perspective?

And.... If it was eating 20Gb I'd be worried, but 20Mb is nothing. Also, remember that what you seen in the task manager is the amount of memory the application has reserved from the OS. Not what is actually used.
