I am trying to get the following VB6 listindex to work within my vb.net
setTheR CStr(payReq.ItemData(payReq.ListIndex))
But if i copy and paste that into VB.net it wont accept it.
This is what VB.net did with the converting of the VB6 to .net
strContract = payReq.Items.Item(payReq.FocusedItem.Index).Text
However, checking that value it returns the name instead of the index. While the VB6 code returns the value of 2311 (which is what it needs to return)
When i add items to the listview i do this:
Item = payReq.Items.Add(rsPayRequests.Fields("userid").Value)
Item.SubItems.Insert(1, New System.Windows.Forms.ListViewItem.ListViewSubItem(Nothing,

But that does not work with my listview in .net since that above is a listbox and not a listview. Is there an equivalent in .net for the listbox to have a custom index?

Most of my check boxes look like these (on the left of the picture) (ignore the checked check box in the upper left corner , I am not talking about tat one) :However , ONLY on tab 2 the check boxes look differently in both cases the check boxes are Disabled , but they don't look the same . Why is that ? I even tried copying the check boxes from tab 3 to tab 2 but to my surprise they once again looked differently ! This only happens on tab 2 . How is this possible ?
View 20 RepliesWhat is the difference in the two blocks of code below? I expected them to return the same result, but they don't.
In the case where xml.@Type = "null", I want PatientMetricTypeID (a nullable Integer) to end up being Nothing.
Block #1: If()
In this case, it ends up as 0. It looks like Nothing is being treated as an Integer and converted to 0. I can sort of see why this might happen but not fully... I would like to understand exactly how this works, and if there is a workaround.
Dim PatientMetricTypeID As Integer? = If(xml.@Type = "null",
Nothing,
CType([Enum].Parse(GetType(PatientMetricTypes), xml.@Type), Integer))
Block #2: If
In this case, it ends up as Nothing -- expected behavior.
Dim PatientMetricTypeID As Integer?
If xml.@Type = "null" Then

Are these two vb methods identical in function
[Code]....
1. This is probably really easy and I'm just missing it. I have 4 tabs in a controller. The contents in all four tabs will be identical (pictures, text boxes etc.) the end user would then add whatever to it. Whenever I try to copy the contents from tab 1 to any other tabs using ctrl+c and ctrl+v they get all out of alignment. Is there a way to duplicate a tab in the editor so that when flipping through the tabs all the text and pictures are in the exact same spot? I'm going out of mind on something that seams so simple.I don't want to have to write down the location of a couple of hundred controls and then retype them all 3 more times.
2. I can also only select text boxes, labels, and pictures at the same time. It will not let me select text boxes, labels, pictures and drawn lines all at the same time. So I can't really copy and paste everything at the same time I have to do it twice which makes the alignment get even more screwed up.
i have n-Strings. Something about 100. But most of them are identical. How could i remove these multiple string and have only each string one time?
View 7 RepliesI made a program with Visual Studio Express 2008, compiled for .Net Framework 3.5
I transferred the .exe and the other 2 files to my brothers laptop who also uses Windows 7, .Net Framework 3.5.
Every time I run the file it says "Windows Application has stopped working..."
However, I run it fine on my PC and it is also Windows 7, .Net Framework 3.5
Can anyone else think of a reason the program won't work on my brothers laptop?
I've just about scrambled my brain on this, searching and trying things, so I'm hoping someone sees something that I'm missing or can explain it to me. I'm new to .NET, used to do a lot of programming in VB but that was many years ago.

View 2 RepliesI have an application which has a tabcontrol that contains two tabpages. I have a custom made usercontrol docked to fill up each of those tabs. When I resize my main form to the minimum size allowed one tab resizes accordingly while the other seems to overflow the area and a couple ui items slip out of access/view.
One usercontrol was quite literally copied from the other and renamed and fields adjusted. The usercontrol size is the same between the two. Within the usercontrols there is a datagridview and a large panel full of textboxes and they have identical sizes and identical anchoring properties and even the same location coordinates.
I'm struggling to find a difference between the two but I really would like the resize behavior to match between the two usercontrols. I was wondering if anyone would have ideas of other things to check I did not mention here?
I wish to insert a row into an SQL table a multiple number of times. The only field that will change is the Primary key ID which will update automatically.
To enter the INSERT into a loop seems very inefficient (time). The only other way I can find to do this is build up an array of values and do a multiple INSERT but again this seems very inefficient (memory) when the values will all be identical.
Is there a way of saying insert this row a variable number of times?

I'm using Visual Basic 2010 Express, on Win7 32bit. My application talks to an Arduino via a virtual com port provided by a cheap Bluetooth to serial adapter. I use a text based protocol that is working fairly well. BUT one method in my code, taht seems functionally equivvalent to the other methods is locking up my whole window.
It does this whether I'm debugging or running the exe.Below are the offending method, and a simmilar one defined above it that works with no problems.

If I comment out the cal to write, everything works fine. Aside from me setting some state bools and playing with button titles in the first method, I can't see the difference as to why one works fine and the other hangs.
I really hope someone has some experience in the SerialPort object and VB that can shed some light on this.I've tried everything I can think of. I thought maybe it was the inline concatenation, so I dim'd a local and assigned the string to it, and passed that to Write. But I have another method that uses inline concatenation that doesn't do this.
I am wondering how to detect that the values in the combobox are the same, as i am doing a application that will show the dates from the combobox. So if there is identical dates in the database, it will show only one date, and when the user clicks on that date which has many entries, it will show all relevant data to that date to a listbox for example.
VB.Net, Visual Std 2008 These 2 fields would use the same table for the display data, but "MyInfo.workState, ie KS" and "MyInfo.homeState, ie TX" would be 2 different fields. How do you avoid syncing the "Display Member" of these 2 comboboxes. In other words, if the user first selects "KS" for the workState combobox, how do you avoid the workState combobox display changing to "TX" when you change homeState combobox to "TX"? Do you have to use different databinding sources for each like combobox.

I added a table to my program and it generated two errors and not it will not build. I have added quite a few tables and this has never happened before. The reeors are:
1. public sub new ' has multiple definitions with identical signatures
2. 'Protected Overrides Sub OnCreateMainForm()' has multiple definitions with identical signatures.
I have deleted the table that I added and tried undoing everything having to do with it but nothing works.
I'm having some very weird issues with interfaces right now.
I have a very simple setup. In one of my class, I have a Property implementing a Property from an Interface.
In my class it's like:
Private _oForm As IForm
Public Property Form As IForm Implements IContainer.Form
Set(value As IForm)
[Code]...
I have like dozens of interfaces like this working throughout my project and I can't believe this simple one can't work!
