This works like a charm... loading DropDownList2 with all the items from DropDownList1 without looping:
DropDownList2.DataSource = DropDownList1.Items;
DropDownList2.DataBind();
But, the data from the item text of DropDownList1 is copied into both the text and value fields of DropDownList2. Is there anyway to get both the text and the value fields to populate properly?

frmAddUser is a simple form that is opened as a dialog by a command button on the primary form (frmPrimary). Once opened, it's only job is to collect information via textbox and combobox fields. Once submitted, the information is added to the database.
This works, or so I thought. If I open this form, fill it out, and submit the information; the record is created. However, if I turn around and do it all again with different information, another record is created but with the previous information (not the new). It will continue to make records as long as I keep submitted this form but no matter what information I put in, it always uses the original information that was used to create the first record.[code]...
The "Details" fields keeps repeating itself for example its showing it 4 times instead of one!this is my code[code...]
View 7 RepliesI want to start a new development thread so I can maintain two versions of a solution. I set up a new directory next to the old and copied the contents of the existing directories into the new. That's all well and good but now I can't update references in the new project to the new directories. I remove a .DLL and when I add it again, it keeps including the .DLL from the old path.
I'm running VS2005 and the solution is made up of 5 or 6 different projects (if that makes a difference.)

so I have a template in Crystal reports using vb.net, I changed my data source location and that source still contains the needed tables for my report, the problem is this... My original template displays the exact report but when I changed its data source it duplicates the data in the details section(e.g I made a query that will show 1 item only,but instead I get 4).
Here is a screenshot of my problem: [URL]
I want to alter the template rather than to make another one
how to make a form quicker to fill out for my work, and it involves having a employee enter a patient's name in one text box, and then having that information duplicated in all other name text boxes.

I have a windows form that is set up like one big calendar for the month of may.when you click on May 1st...another form (form2) opens up with some combo boxes and a datagridView on it. What I need to do is on Form 1 (my calendar form)when you click on May 2nd...I want to open a duplicate form 2..the one with all the combo boxes on it.do I have to make 30 duplicate forms ( for 31 days of May)or is there an easier way to make sure that when the user clicks on May2...they dont get a form filled with May1 stuff.I can see that there is going to be a problem as it sits now because I am going to be adding to form 2 some kind of date box, or a date field in my gridview..So I need each form to display the right date?

View 1 RepliesI'm designing an app that resets permissions on folders so I've made a treeview that uses GetDirectories to populate itself with all folders on a user's computer. The TreeView has the "checkboxes" property set to true so the idea is that users select all of the folders from this treeview that they want to reset permissions on and then click go.
So once they click go I need to loop through all nodes in the treeview and all subnodes etc and test to see if they are checked, then if they are I want to add each node to a list and then in the next routine I would loop through the list and reset the permissions.This is what I am doing at the moment but I keep finding that the objects added to my list are duplicated.For example if I select C:Test and C:TestTest2 in my treeview then I end up with my List looking like this:

I am new to vb-net and am self-teaching and developing an application to combine a number of tasks which use different apps at the moment. I have a routine to ftp upload files but I am duplicating effort by uploading even if the file exists. Is there a simple "file exists()" type solution similar to:
If System.IO.File.Exists(strPic) = True Then so that file is only uploaded if it does not already exist?
I don't want to actually MAKE the pong easter egg, but for anyone with Dreamweaver, try typing 'dreamweaver' into the color selection box to play a round of pong.The bit that I want to know how it works is the bit at the end once you lose.After your loss, it will immediately play a small tune, whether or not your volume is on. In fact, it plays whether or not you have speakers, which makes me think the sound card itself is playing the tune.How can you achieve a similar effect, playing notes without sound or speakers, in vb.net? I would imagine this requires P/Invoke, seeing as there is no obvious way inside the framework.I don't need a whole song, a simple beep or the ability to change frequency of the beep will suffice.

The exclusion list works great, but it duplicates each item in the ListView several times. How many depends on how many items that it excludes.

I'm trying to write a program right now for my computer science class for a program where you insert text into a text box, (the text being a password), and then click a submit button. The goal of the assignment is to have a program that looks at the user given password and see if it matches the const password (or one of the three const passwords in my case). If it doesn't, it is supposed to loop back so you can re-input the password. Also, If you enter the correct password, the loop ends and you are to get a msgbox (or, in my case three different ones), and then the application closes. We are to write the code so that if the password is wrong "x" (insert 3 as the number I have chosen), a MsgBox will pop up with a message saying
something along the lines of "you have gotten the password wrong to many times.", and then the application is supposed to close. I don't think I could rant on much more, I've done a good (or in my eyes terrible) job of summarizing the assignment.
[Code]...
My problem (aside from, I don't know, a problem with my code itself) is that when It reaches the loop, it goes through all the code again, but I'm unable to change the user given password, and so it just pops up the three failed password entry MsgBoxes (the code for which is temporarily removed), then the failed to many times MsgBox, OR one of the successful message boxes. What I'm wondering is if anyone can help me fix my code so that it functions as desired.

View 10 RepliesOn a form I have a series of 20 checkboxes (cbS1 through cbS20). With that I have an integer named 'Count'
What I need to do: When the forms loads it will get a value for Count. I need all the checkboxes that are greater than this value to be checked.
So if count = 7 then cbS8 through cbS20 will be checked.
Im not really sure the best way to code this is. I know I can do it with a giant case statement...but there has got to be a better way right?

So basically the data contains events, runners and odds. I'm looping through and assigning the variables to the relevant object propeties, alls fine.
The problem comes when I'm checking the next runner id (or event id) to see if it's changed so that I know to create a new object. Well in checking that the id has changed I've already moved one record too far so every time I'm changing to a new id I'm losing one record.
