View 4 RepliesI have a listview (details) with owner draw set to true (so i could make rows alternate in color, looks cooler) which basically contains items and subitems whose texts reflect status info that updates constantly
the problem is, sometimes (if the task runs quickly) the status changes really quickly, and as a result, listview items "flicker" for a millisecond no error, no real problem, its just really annoying and makes the program look less professional.
Is there a way to make the listview not flicker? Or maybe there is a way to make it so that the listview doesn't process too many drawsubitem calls during the same time interval? or maybe there is some customized list view out there that does the trick better?
NOTE: i tried with owner draw set to false. it flickers less, but still flickers. same problem :S
Also NOTE: i am not making cross-thread calls. i have 50 items in the listview and 4 colums, mainly the last 2 subitems change.

I am using visual studio vb 2005 and I searched the forums for an answer to this but didn't find exactly what I was looking for. I am using the following code to populate a list box. What I want is to have a datagrid view show the results of a dataset that is generated when a user selects something from the list box. I know how to generate the dataset, but I'm not sure how to bind that to a datagrid view and I'm not sure what event I should use from the list box.[code]

View 1 RepliesI am creating a program that allows a user to view a list of foods in a combo box, add that food unto a list box, and adds all of the calories of that food together. When the user highlights their select food, the program automatically shows the amount of calories for that particular food in a text box. The program is getting the food and calorie information from an access database. I managed to get all of the food calories to add up properly, however, I ran into a problem. Sometimes, well, most of the time, when I select certain foods from the combo box, the program automatically reselects another random food, usually a food that begins with either an A, B, or C. Also, the other random food that the program chooses usually has the same amount of calories as the food I originally wanted to choose. I have over 6,000 items in the database. I don't understand why this is happening. This is what my code looks like for the button that adds each food to the list box:
Private Sub Button4_Click(sender As System.Object, e As System.EventArgs) Handles Button4.Click
Foods_Selected.Items.Add(ComboBox1.Text)
Static i As Single
[CODE]...
And this is what my code looks like for the button that adds all of the foods together:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim x As Single
Dim TotalCalories As Single
[CODE]...
I have no idea what to try. It's like the program just skips over random foods, even though all of the information for them is in the database.
any simple coding that uses 2 buttons, allowing the items in listbox to be moved either up or down?I have been finding complex codes rather than simple ones. can someone help me on this?

View 4 RepliesI seem to be having issues with the selected index on a list box.
The list box is having various items inserted depending on the user selection. An example would be:
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "Item1")
LiIndex = ListBox1.Items.Count
ListBox1.Items.Insert(LiIndex, "AND")
[CODE]......................
This all work and displays without a problem. The issue I have is if I select the second of the two AND's. If I click the second "AND" in the list and then a button to fire a method, the selected index is always the index of the first "AND". Dim listIndex as integer = ListBox1.SelectedIndex
I can't work out why, the listbox itself will always show the second one as selected, but the action will happen against the first one.

View 6 RepliesI am using the code from the following link. Basically I am using the built in functions in visual basic for encryption (Cryptography). Seeing as there is a lot of code for it, I posted a link to the code I am using.

I get what this is doing and how it is doing it...for the most part. My question is how do you let the user set the key to be used instead of it randomly generating one? One of the reasons I want this over the random key is that the user will be able to remember it easier and the key generated sometimes has weird characters in it that not everyone will no how to use. I have tried everything I can think of.
The encryption works good, all I am using it for is to encrypt/decrypt a text document. If this is not too good of an encryption, that does not matter as I am not using it to encrypt any highly sensitive information. All I need is a way to be able to allow the user to set the key, but every time I try to pass a string through the encryption() method instead of a generated key (in the generateKey() method) it will give me an error.
I'm wondering how would I go about allowing a user to set up an account on a program and as button whn they click on asking their log details? And when they do log On. A pop up saying their name welcome to this program?
