.Net Substitute For CoCreateGUID() In VB6?
Jun 8, 2009I need to generate a GUID so I can store into a table and the create related records (to be filled in later) in 3 other tables. Used to be easy in VB6 with the CoCreateGuid() function. But I'm not seeing anything in VB.Net help files to match. Trying to use this function I get all kinds of COM errors. So I guess I can import several COM/DCOM classes to make it work, but maybe the overhead isn't worth it.

I gather that this process could be used to define the size of an array that is not known at creation, but becomes known later in the program. VB2010, however, doesn't like this code at all, and tells me ReDim can no longer be used to this end. Why? And is there an easy replacement for this?

.net - Substitute/disable Control Components For Development/testing?
Feb 2, 2012I have a VB form that contains controls for interfacing with some hardware (video cameras, motors, etc) on the machine it is to be deployed on, but I'm usually not at the location of said machine (it's a 3-hour drive away). I'm trying to work on the project while on my laptop, but obviously the controls will generate all sorts of errors since they can't talk to the hardware.
I was thinking of replacing the control types with my own mock control classes, then use #if directives to control whether I'm building for the real machine or my test machine. Problem is, some of the affected code is in the form designer-generated code section; the form designer automatically tries to "correct" my changes, so I'd have to manually put them back all the time, and try to remember not to commit the form designer's edits into version control.

Bindingsource AddNew() And CancelEdit() Interaction?
Dec 21, 2011I think I started out with a misunderstanding of what happens with addnew() and canceledit().
I have a strongly typed datasource in memory.
I call bindingsource.AddNew()
Later I find that the record the user was trying to add already exists, so
bindingsource.CancelEdit()
I have not set any properties other than datasource on the bindingsource.
My assumption was that the CancelEdit() would rollback the blank row added by the AddNew(), but I'm getting some odd errors which lead me to believe this is not true.
Could someone verify that CancelEdit() leaves the new row?
Bound Datagridview Addnew With Variables?
Feb 23, 2011I am trying to use a bound datagridview and through the add button on the bindingnavigator adding a new row to the bindingsource and then pass two variables to the datagridview in the new row so they can be associated with the proper ids. I then have a save button for when the end user is done inputting the rest of the data for that record.
The code is below:
Private Sub BindingNavigator1AddItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
AddressesBindingSource.AddNew()
AddressesDataGridView.CurrentRow.Cells("caseNumber").Value = Me.CaseNumberTextBox
AddressesDataGridView.CurrentRow.Cells("interestID").Value = Me.InterestIDTextBox
End Sub

Pre-fill Data Bindingsource Addnew
Aug 21, 2011Im using a bindingsource to add new records to my db using bindingsource.addnew()When this is evoked, it seems to automatically increment the recordcount and then blanks out the content of every bound to that tables bindingsource. So that all fields in the new record have to be filled in manually.I would like to be able to pre-fill some of the data in the new record. for instance, when a user adds a new record, have a specific column in the new record automatically populate with the selectedvalue of a combobox.I assume this means I may have to manually code up my own addnew routine, but google has let me down on where to start.

AddNew - Form Where Show A List Of My Rows With A Given A Table
Jan 19, 2009My problem with AddNew. It really is somewhat simple, but I can't figure out the solution. I have a form where I show a list of my rows with a given a table. The user can then select a row and press clone, which then will try to make a copy of that row.
Here is a snippet:
Dim rowToCopy As cmaDBDataSet.cmaPropertyRecRow
Dim originalID, newID As Integer
rowToCopy = CType(CType(Me.CmaPropertyRecBindingSource.Current, DataRowView).Row, cmaDBDataSet.cmaPropertyRecRow)
originalID = rowToCopy.id ' id of row to be copied
[CODE]...
.... and continue to copy the rest of the data to the newrow...One of the items in the row is obviously a primary key called id. I can not copy this data since I am creating a new row. My problem is, how do I set that value!? or atleast retrieve the value for the newly added table. I need that value so that I can call another form to actually allow the user to modify this newly cloned data. I tried using EndEdit, UpdateAll, no worky. THen I thought I could assume that the newly added row would go at the end of the table so I used MovedLast then got the currentRow id from there... That worked well until we did some deletes within the table.

View 2 RepliesHow To Pass A Function To A Function Is Functors/function Objects Avaiable In VB2010
Oct 12, 2011I want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.
