I have a listview with four columns (category, name, date , amount). More than one items falls in a category and I mark them with a number. ex - different kinds of pens as no.5. So, if I make an entry of five pens, five "5"s shows up in the category column. I want to display only one "5" in the category column and not to make it crowded with same numbers.
View 5 RepliesI have to create a report that lists tests that a student has taken and how they answered each question...the column header layout (roughly) looks like:
Test #1 1 2 3 4 5 Test #2 1 2 3 4 5
TestA A B C D E TestB C C B C E
The problem is that the Gridview doesn't seem to like repetitive column names and is renaming the second set of Question #s to something else.
I have 4 Columns in a ListView. The first one is called Serial No. Every time I populate it, the serial number increases automatically. After populating the ListView couple of times, I select any row(s) and remove it. When I remove one or more row(s) from the listview, serial numbers stays same. I want the serial numbers to be fixed automatically when I remove any number of row(s). How can I do that ??? Here is my code -

How to create a function to find the largest value(subitem) within a listview column
View 11 RepliesI have added three columns to the ListView control,
listView1.Columns.Add("id", listView1.Width / 3); listView1.Columns.Add("Name", listView1.Width / 3); listView1.Columns.Add("Address", listView1.Width / 3);
Assume the ListView1.Width is "30", then each column should be in event width of 10. Furthermore thereshould only be three columns becuase i have added only three columns. However, when i resize teh form, the listview controls shows an additional column.
How this was added? How do i fix this, so that when i add 3 columns it will have only three columns even when resized the form or not

I wrote a function to format numbers like this: 123456100,12 -> 123.456.100,12 (I have a function too, which converts numbers from this strings).Now, I have a dgv and a column with these numbers (or rather strings). The sort mode is set to automatic. If I sort the column, it doesn't work, because the values are not really numbers, but strings. But I get the same result (the sorting doesn't work), if I use the formatnumber function (this returns strings too).
I could use the programmatic sort mode and before sorting I format the strings to numbers, then sort the column, and then format the numbers like above. But this is a bit slow (the dgv has appr. 800 rows), and in this case, I haven't an arrow next to the column header text.is it possible to sort the column like a normal number-column with automatic sortmode?
I am trying to do repetitive loads of images to one picture box. That is: An image is loaded to the picture box from a bitmap image.It is done this way so the image can be scrolled using the mouse.That works fine.The image is loaded from a file.When I attempt to load a second image from a file, I get an error indicating that the resource has not been released.I have tried Dispose() etc, nothing seems to be working.I started with VB 1.0 and worked up through VB6 over the years and am now transitioning to VS 2010. A bit of a neck snapper, but it seems to be worth it.

I am trying to find a solution, in eliminating repetitive string names, say for ex.,in a literal field, i am populating names of the contributor of certain article's history version, and so, if "ron" has contributed to the versioning of an article 3 times, the name "ron" gets added to this literal control, and outputs "ron" 3 times.
View 5 RepliesRepetitive Statements: Looking for an alternative to a function or subroutine. Years ago, I wrote programs for a company using a language called "Algol", I am sure some of you know of it and but many more do not, it is a pretty old language. It had a capability that I used called a "Define" where you could take a statement (for example x = y + z ) and create a 'define' which was a simple, short replication of that statement. (x=y+z) could be defined as 'mysum'. You could then use 'mysum' any where in the program in place of the 'x=y+z' statement.

Is there a similar type capability in Visual Basic? A sub routine does not satisfy the need unless the variables x, y and z are globally dimensioned to the module? I can do this, but would prefer not to. I am expect there is a similar capability, but I personally have only scratched the surface of the VB capabilities.
I have a lot of repetitive code that references components of my main form. I wanted to create a separate module (correct terminology?) for all this code to be contained. I cut the offending code and pasted it into my new module, changing each label reference, etc to form1.label.click
Form1 was then underlined and I get this message:Handles clause requires WithEvents variable defined in the containing type or one of its base types.I think I'm headed in the right direction, but what exactly am I looking for? Here is a sampling of the code that I would like to keep in a separate place other than Form1.vb:

I am stuck on hiding a column in listview. I want to hide the items in that column as well. I tried setting the width to 0 but the user can still size it out and see it.
