I am using reportview to set up my report pages. I used the existing datasets(configure -->add table -->save) but every time I clicked save, I got a few errors. So I decided to create new datasets for the tables that I want to have reports. Is that the right thing to do?

View 3 RepliesI have connected my sql db with vb and I m trying to make a UI. My question is that when I write code in order to create datatables and I fill them with the results of queries I've created, where do these datatables belong? I'm wondering if I have to define a new dataset or do they belong to the existed dataset which is created by the dataset configuration wizard??

I try to compile a project with msbuild.exe I have this error :
vbc : error BC30136: Error creating Win32 resources: Error reading icon '"Recycle Bin Empty.ico"' -- The filename, directory name, or volume label syntax is incorrect.
This icon is the Application icon which is in the same directory of the project.vbc is started with /win32icon:"Recycle Bin Empty.ico" parameter.Don't know why MSBuild can't reach the file.
Can you please explain me and/or show some good tutorials how to do it?It seems pretty complicated because visual studio usually does it all for you and that made me stupid and not to do anything about it.Things I don't know to do in code but I know VS does it for me:

I'm sure there is a good tutorial somewhere on the internet. I'm okay with doing it with designer, but now when I have a situation where I can't use MDI container but tabcontrol.Other solution would be to make a MDI container out of tabcontrol. Is it posible or only other form can be MDI container.
I got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown". I have noticed it that it doesnt show error message for those form which have few labels and text boxes. It shows error message for those forms which have 1 menu bar, 2 picture boxes(one is 1280,1024 & another is 250,456), 2 group boxes, 40 labels, 3 combo boxes, 38 text boxes & three buttons. Please help me I need to get rid of this problem. Does it mean that I cant use unlimited control there in my form?

I don't normally use strongly typed datasets, but I am maintaining an existing application that uses them.This application has a form to edit rows in detail view, so we have the navigator toolstrip with nav buttons on top, including one to add a new row.When this button is clicked, I need to update one of the bound text boxes with a value from the underlyingThe field in question is defined as nvarchar 25 It's almost always integers in this field, but one row has a string.In the dataset, I have a table adapter to go get the max value + 1 where the field is numeric, like this:

I am using VB.NET 2008 Express. I had a project with a mdi parent and several child forms. On the child forms, I created a datagridview by dragging the necessary table from the dataset(s) from the data sources window.
Main form - PastorBase
Child form - IllustrationList
When I try to debug it, I run into several errors from the code of the IllustrationList.Designer.vb file in this section [Code] However, the moment I make any change to the control by modifying properties or simply resizing it on the form, my change in this code is lost. So I am repeatedly having to change these lines (there are about five per child form). I am uncertain of what I am doing wrong. Should the dataset, etc. be added to the parent form and then called from the child form? Is there some setting I need to change somewhere?
I have a dataset in my application that I fill using tableadapters like this:
Class Form1:
sub new()
Database = new Database
end sub
Class Database:
sub new()
tblLalalalaTableAdapter.Fill(DataSet.tblLalalala)
end sub
I am told it is too early to call the tableadapter.fill method inside the constructor. If the database is unavailable now, the application won't even start. It will just kinda crash. What is the proper way to do this? When should I call the tableadapter.fill methods?

invRecord.Pack_Num is a field of type Integer. This means that when I try to access it, if it is DBNull I get a StronglyTypedException. The above code throws this exception. If, however, I remove the "invRecord.Pack_Num = PSNum" and in its place put something like "True", the code works fine. So I guess my question is, why is that that invRecord.IsPack_NumNull() returns False when the value is in fact DBNull and what can I use as a conditional instead? I've been beating my head against the wall for a while now and I can't find a solution to this problem.
