View 2 RepliesI am trying to use the combobox to update/edit/view the saved data (in contact form) from sql server.
My Load_Combobox (in contact form):
Private Sub Load_Combobox()
'Type
cboType.Items.Add("Director")
cboType.Items.Add("Principal")
cboType.Items.Add("Project Manager")
cboType.Items.Add("Technical Manager")
[Code] .....
The problem now is when I saved a record into sql server (EG Technical Manager) and try to view back the saved data, it always show the first item (Director) in combobox. But, my sql server has saved is "Technical Manager" for that saved record.

highlight/select an column and each column in the entire row, doubleclick the row, and populated a form with the .selecteditems(0) and subitems(0) to the text controls on the called form?
I have a form that adds new contacts. New contacts are added by pressing an appropriate button and they appear as an entry in the list on the form. I try now to add an edit button that will edit existing entries.User will select a given entry on the list and press edit button and will be presented with an appropriate form (AddContFrm).Right now it simply adds another entry with the same title. Logic is handled in a class called Contact.vb Here is my code.

I'm really new at programming and was looking for guidance about a project I have.I have to design a program that administers a multiple choice test to users. It delivers questions one at a time, from a predefined test file for the user to answer. It also marks and displays a score at the end of the test.
First, a QUESTION form verify's the user's registration status and access. The user provides a registration number and password and the program reads it from a "registration.txt" file to determine if the user is eligible to take the test (i.e., they are registered to take it). If it is correct, then the user presses the "Begin" button. If not, then a message appears and the student tries again to enter the information.
A read only text box will display the score at the end of the test (String with format correct/total) and the user can't retake the test.Second, a QUESTION form opens after clicking "Begin" on the entry form. The questions are going to be from a "testfile.txt" file.Each question is on multiple lines in the file. The first line consists of the question followed by possible answers followed by the correct answer ( 3 items are separated by "#"). The current question number and the question will be displayed in textboxes.'n'= possible answers; so each of the next 'n' lines provides a possible answer. All possible answers will be displayed in a Listbox.After the user selects an answer, an ''Enter'' button is pressed. This will submit and evaluate the answer. If nothing is selected a textbox should appear and display the error message (APPEARS ONLY IF THERE IS AN ERROR). After pressing ''Enter'', the next question is displayed.When all questions answered, the entry form is displayed again and displays the score.
I know that's a lot of information, but I wanted it to be really clear. Would it be best to cycle/loop the questions with a DoWhile loop? And how would I store the answers while the user goes through the test?

I need test data for a IP Subnet calculator I have developed. I have tested some obvious scenarios, and all seems good, but the person developing can often be the wrong person to test. The calculator can do one of two things:
1 - given an existing network and CIDR(mask), and a new CIDR it will create a number of networks with the appropriate number of hosts.
2 - given an existing network and CIDR(mask), and a list of c,h, (c = count, h=number of hosts) it will create the networks.

I would like to develop a very simple question-answer program whereby there is a user form with a label which contains the question, a text box where the user enters the answer and a button that the user clicks to change to the next question. This should be rather simple but I would like to have about 500 questions in the end (will be slowly adding more questions).

i would like for my first project to be a CPU stress testing program (kind of like Core Damage or Intel Burn Test).I have no problem designing the form, but how and where should I start? I've done some searching, but haven't really found much. I think the reason for that is because nobody is really going to just give out source code for anything (which is completely understandable).
The main thing I would like to understand is what exactly makes the CPU work at 100%? And how could I design it to where it automatically determines the amount of cores/threads the CPU has, and utilize them 100% without having to open up one instance for each? Or is that jumping too far ahead?
EDIT > I know that I'll need to create some kind of loop for the CPU to process over and over until closed. I was thinking something along the lines of calculating Pi to 32 million digits or something like that.
> Another goal is to have some sort of error checking capability. I am an overclocker, and I would like to have this ability with this program. For example, it I make it to calculate Pi, then I would like for it to tell me if there were any errors in the digits it produced.

I'm not sure where I'm going wrong with this. it's supposed to let the user add scores to the list, then calculate the total, average, and count. However, it doesn't let me add more values to the list. Any help whatsoever would be awesome!

i have a problem with editing data in datagridview in vb.net 2005
View 2 RepliesI have a datagridview that is bound to a Dataset I have created. My question is, how hard is it to be able to edit/add data to these rows? It looks as though the Dataset is actually a query of somesort (which you obviously can't edit) Is there a way to link directly to the table for editing? I know you can do this using queries, etc... but I'm thinking there should be an easier way.

View 1 Replieshow do i add columns to a listbox??
And Checkedlistbox add and edit more than 1 data per item. So if you take a look at Cheat engine it got 3 data per row. 1: the checkbox, 2: the item name and 3 the value i want to change if i doubleclick (all this in same row)
So if you take a look at A cheat engine Video at you tube you can see the checked listbox that you can freeze things and change values so more thann 1 data.
