I have a form with a Listview. I have not manually added columns through the gui so I need to do this too.I have a stored procedure which returns two sets of data. One is titled url and the other occurrences in he procedure.I have bound the results to a dataset. I am having problems taking that dataset and putting the results in the listview. Here is the code I have:
[code]...
It is not creating the column headers. It is not putting both results in the view. It is only putting the first column "url" It is not putting the next row on the next line, but placing it in the next column where the occurrences should be going. It is also not resizing the columns to match the data , but keeping at the size assigned (I assume) in the columns.add section.

The table has data!
I have a dataset that I search using the
dataset.tables("table").Select("WHERE clause")
method to query. I then use a datarepeater to display the results. Is there a way to programatically tell if no results are returned? I'm aware of the Dataset.tables.Rows.count, but can this be done after the select method?

i have a sql database, and have created a dataset for a sample table in it.The dataset is HotelDataSet2 and data table adapter to insert to it is Various_itemsTableAdapter.
MsgBox(HotelDataSet2.various_items.Rows.Count)
Various_itemsTableAdapter.Insert(Item_nameTextBox.Text, itemcode, PackingTextBox.Text, UomTextBox.Text, PriceTextBox.Text, RemarksTextBox.Text, TaxTextBox.Text, StatusCheckBox.Checked, Rate_inclusiveCheckBox.Checked)
MsgBox(HotelDataSet2.various_items.Rows.Count)
This always reflects the same count, before and after inserting..But if i execute this
[Code]...
it shows the new count to be +1 of the old one. So i concluded that everytime i change some data to the table via table adapter, i have to always refill the dataset?? How is that useful then??
I have a piece of software with two tabs, inside each tab there are buttons (the user can add the buttons when they want). when tab1 is full tab2 should start to fill. I currently know how many buttons fit on the screen so I just say something like if buttons > 150 then start to populate tab 2 The problem i have now though is if the resolution is changed then a different amount of buttons can be displayed. so if I put my screen to 1280x720 some buttons are left of. I was thinking of detecting the resolution and then using different cases for different resolutions but this seems very inefficient im wondering if there is a different way?

View 1 RepliesI have some reports that I use with the MS ReportViewer and I need to get a count of the physical pages (as opposed to logical page count) to use with a print dialog.

The only publicly accessible property gives the logical page count.

this its a very silly problem i have with CheckBoxList control, i dont know if its just me or what but the whole idea of the control its just great but the implementation its very confusing.

What I would like to do is to have four different buttons (e.g., buttonA, buttonB, buttonC and button D). I wanna give the following instruction to the people: press these buttons in the following order: first buttonA, then buttonB, then buttonC and last buttonD. If they obey this instruction then a picture will be displayed, for instance a happy face. All the other combinations will not activate this picture to be displayed, or in other words, there won't be any consequence. I would also like to save this data using windows note pad e.g., writeline (1, xxxxxx). Is there any chance I will make it?

View 3 RepliesI am currently creating a program that outputs an image, but the image being outputted consists of text and other graphical elements.
So the text element would look like:
graphics.DrawString(text, variable, variable, variable, variable)
My problem is that I cannot create more than one set of each element that I am creating. And then put that into the code that creates the image. Is there a way of creating this line of code and then putting it into say a variable and then putting the variable into the code where the image is created?

View 6 RepliesI need a little advice in manipulating DataGridView in Visual Basic .Net. This is my first time playing with DataGridView. My program is to load a .txt file containing data of every room in a building and display them in the DataGridView. Here is a portion of the file showing 2 rooms:

Or am I doing it wrong?
