i am trying to get an output from a data grid view into a text file and align it properly into columns. i have been able to get the output into the text file.. but they are not properly aligned as they appear in the data grid view. They always appear this way

I want to align a sample of data that is reproduced in the ListBox so that it would look neat. However, I have failed to find any alignment related property available for ListBoxes. Therefore, I would appreciate an expert advise on how to invoke it without extensive coding.
View 1 RepliesI am writing to a txt file from vb.net. I cant write 2 columns of data and have the 2nd col start at same place. Col1 is OK but col2 starts at different places depending on how big col1 ,row data is. How do I force this as currently I use tabs but again this doesn't work.
Private Sub write_file()
w = File.AppendText(filename)
eqNo += 1
count += 1
If count > 2 Then '2nd col

I need it to look like the following:

I've seen several representations of how to do this in VB6, but I would prefer managed code (VB.net). Also, I want to make sure that what appears in the textbox will translate to the printed page the same way.

So I am adding StaticTextField controls to a page. This is using ExtJS, but we use VB.NET methods to add ExtJS so we don't actually have to write it.I tried using
.Style = "text-align:right"But that isn't working, in fact it isn't doing anything. Here is the whole code of one of the controls:

Anyone have any idea why these aren't right aligning using CSS? For some reason, if I try to use the same code above (the CSS), to try and right align comboboxes, or number fields, it works, and they are located right underneath these static controls, but it's not working for static controls. They need to be static because we don't want the "box" outline on each of the values, we just want it to be text, nothing else on the screen.
i created a panel with few buttons, all buttons have the same size, most buttons hold images, 2 of them hold string (1 or 2 digit) the string buttons will not align with the rest of them, and i have no idea why ?

I am creating a project in VB.NET in which one of the reports require that the name of employees should be displayed as column names and whatever work they have done for a stated period should appear in rows below that particular column.Now as it is clear, the columns will have to be added at runtime. Am using an ODBC Data source to populate the grid. Also since a loop will have to be done to find out the work done by employees individually, so the number of rows under one column might be less or more than the rows in the next column.Is there a way to create an empty data table and then update its contents based on columns and not add data based on addition of new rows.

View 5 RepliesI converted a VB6 application to VB.Net and in doing so, I seem to have lost the ability to auto-align the controls on the form. I thought I could change that in the "Tools > Options > Windows Forms Designer > General" area but that doesn't seem to work. Anyone have any ideas? I really don't need to use a grid for aligning since the auto-align functionality can be used but I just don't know how to get it back.

I have a form on with I have a label inside a panel, with a button I can open a fontdialog and change the font of the label (inside the panel). The font (name and size) I also display in 2 textboxes. This works as far. But I also want to display in a different label (so not the same as the label inside the panel) which fontstyle is selected (at this point when I select bold, the number 1 is displayed in the label, but I want to the word Bold displayed. Also I found out that when I make the fontsize smaller, the label inside the panel isn't align in the middle of the panel.

I am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.

I have a procedure that sets a datatable variable called dtP equal to prpParametersTable at the beginning of the procedure. I then add three new columns to dtP.Here is my problem.
