7 fricken hrs and all it was is was is I had to change how I added the columns to the DGV/


Me.BidModuleDataGridView.Columns.Insert(x, StaffColumn)

insert instead of .Add

WOW

Thanks for...

I GIVE :mad:

I've spent the better half of 6 hrs now trying to get this DGV to work.

What I'm trying to do is create a DGV at runtime and create the columns from a list of strings that I have...

well again, it looks like a designer thing.

I deleted the datasource wizard created combo box. Picked one out of the tool box and hand coded the bindings. Everything works fine.

Just for my...

I think I had this problem quite a while back but can't seem to find that thread, anyway I'll explain what I want and the behavior I'm getting .

So I want:
1)Combo's drop down list to be filled...

Well I was able to recover the designer file. but no luck with the others.

You want to know whats so disheartening about this: I had just finished fully testing form for operations, it was...

Boy I f'd up this time. I accidentally deleted a form from my solution explorer, is there anyway to recover it? Funny it did not go to my recycling bin. So is there a setting for that also.

Yea, why would you. I'm probably the only one that tries this crap.

I'm sure they're are other ways to accomplish...

1) Dragging a table as a dataGridView onto the designer creates a DataSet, BindingSource and BindingNavigator.
2) I get the same results if I drag only a field as maybe a combo onto a clean form. ...

Question regarding drag and drop to designer and the autogenerated code and components.

Am I doing something wrong or if VS just not capable of this when my datasets and table adapters are in...

Thanks for the reassurance, That was my original thought however too much thinking leads me to doubting myself.

In a basic 3 tier/layer application, Presentation Layer, Business Layer, Data Layer where should a Binding Source live.
Because I have TableAdapters in the BLL with there CRUD logic, it make sense...

ok but VS 13 included the 4.5.1 framework which by your account is not installed on your "home computer" was the app developed targeting the 4.5.1 framework?

Here is a article worth looking at if your considering retargeting.

Could I suggest that you change your exception handleing to: MsgBox(ex.tostring, MsgBoxStyle.Critical Or MsgBoxStyle.OkOnly, "Error")

Have you output window open to watch the code execute.

Good point for us that develop on older platforms. Which I tend to do on purpose, It allows me to catch maybe some of the compatibility issues sooner rather than later.

I generally develop on...

I think the first question is how was the deployment package built. IE: ClickOnce or InstallShield or what.
Both JMC and SS point to a dependency issue. So if your handrolling your own installation...

going along with the .GetChanges of the DataSet


Dim UpdatedDs As DataSet = OneDataDataSet.GetChanges(DataRowState.Modified)

Changing one field even with the flag set returns a...

Thanks for the help Techgnome.
I have it working now, but have a question regarding the following lines:


Dim UpdatedStaffTable As DataTable = OneDataDataSet.IDStaff.GetChanges()

UpdateStaffTable is a flailing attempt to get my database updated. Originally it was a function passing in the staff table, but that didn't work soooo I changed it to a sub and passed in the dataset,...

Hi, I'm brand new to WCF and have followed the MSDN sample of how to load a datagridview with data in a Tier'ed architecture using a WCF service.

The walk through is missing the "how to update...

This is what I kind-of thought.




This is my own challenge: To separate the ways of getting data based on the reason or logic.
I have become very accustom to using strongly typed datasets,...

So if I'm following correctly:

Use ExecuteScalar in query's where I only need to return a single value. Seems to me there has to be a reader somewhere but maybe that's getting too technical....

Thanks to all who have gave input especially dday9, you rock.

Ahh ha, damn-it batman they caught me.

It was indeed in the sql Count function.

Looks like I have some research to do now on DataReader and ExecuteScalar. I wish to learn the difference, since...

Sorry, you guys must feel like your wasting your time but, :blush:

1) I really do get the need for parameters, although it sure doesn't look like it i'd admit.
1) I don't get to choose weather to...

Public Function RowCount(ByVal username As String, ByVal pcName As String, ByVal Password As String) As Integer

'Declare the object to return

My problem was in the SQL statement, where the password could be a null string, either in the db or in as user input

As dday9 suggests:



If either the UserName and PcName differs from the...

Much appreciated guys.

I took JMC's approach, modified my code and created a Class to call from my App.

can you take a look at this to see if it needs anything more.

I need a little help with this.
I don't usually use a DataReader in this way but now have a need for a one way, forward communication this allows.

Anyway I got this code for the reader off the...

Glad you figured it out.


Sorry but data binding controls isn't always intuitive even though it is straight forward once you know what you need to know.

Using a DGV isn't exactly figuring it...

You can move file through cut and paste, however I think (just can't remember) if you try to create a new item from a existing item you'll lose your handlers.
So be careful how you do this. Also if...

I would suggest that you visit the database section on http://www.homeandlearn.co.uk/NET/vbNet.html first, then come back and ask questions, You clearly have not done enough research is this is all...

:blush: Yes this is what I was trying to refer to. Thanks Shaggy

Not really sure what your asking. But here's a shot.

I think you'll need to create a installation package. Then the prerequisites for this .exe will be installed on the target machine.

So, no...

You can also do it by code, which in my opinion is better. The advantage I think is the ability to change formatting faster.

typing this:


DGV1.columns(0).defaultcellstyle.format = "N2"

is...

This is confusing because Select Case is a conditional statement used in VB. Maybe it should say I have a listbox with multiple cases?

isn't or shouldn't strValue evaluate to boolean?

Question: is the dgv bound?

This might be what your looking for.

I suppose this is why you can create a inherited Form. So set up a template Form that you like and just add other Forms that inherit from that.
