VS 2008 - Merge Two Text Files (Rows And Columns)

Jan 28, 2011

I have two text files. The first text file has the format:
ID h1 h2 h3
a 1 5 7
b 3 3 5
c 0 4 8

And the second file:
ID h4 h5 h6
a 2 4 9
b 3 6 1
b 4 1 5

Now I want to merge two files. The output likes
ID h1 h2 h3 h4 h5 h6
a 1 5 7 2 4 9
b 3 3 5 3 6 1
b 4 1 5
c 0 4 8

The two files has the same rows and columns. For the first rows(except header) in the two files, they have the same first column. Therefore just a simple append. The final first row becomes
a 1 5 7 2 4 9
The question is in the first only has one
and the second file has two

I want the maximum count of items from each list in the resultant list. I put some white spaces after "b" then append strings.
b 4 1 5
For key "c", because it is only in the first file and not in the second file, so I append white spaces after the corresponding strings.

Slow Resizing Of A TableLayoutPanel?

Jan 26, 2010

Resizing a form with a TableLayoutPanel is very slow. The form is blinking and it lasts seconds before the form is resized.To find the problem I do the following:

- Make a new windows application

- Add a TableLayoutPanel with 5 rows and 7 columns

- In Form1_Load every cell is filled with a label control.The property Text is set.

- Run the example

Resizing the form is very slow.

What can I do to make resizing faster? Is a TableLayoutPanel always slow when resizing?

TableLayoutPanel Design With DataSource?

Mar 28, 2012

I have created a database using SQL Compact that has two tables.  One table called tblRack contains the following columns;


On my form, I have labels for each RackID.  What I want to do is use the TableLayoutPanel to create a layout like this.Here is the code that is generated by the control;

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
'TODO: This line of code loads data into the 'WarehouseInventoryDataSet.tblRack' table. You can move, or remove it, as needed.
End Sub

But nothing is returned, ColumnCount property = 2, Columns = Collection, GrowStyle = Auto.  Basically what I want to control to do is sort through the records and return a value in each cell, 2 columns, auto expanding.Do I need to have a separate control for each field in the table or can I dynamically create a control like a TextBox?

TableLayoutPanel/Button Controls Being Very Odd?

Jul 17, 2009

I have a class here that is misbehaving, and I can't understand why.Basically, when resizing to make this Form smaller, the buttons begin to extend outside of the TableLayoutPanel that contains them. This is not ideal.This is not an issue about resizing, my project does not allow resizing the main form, the problem occurs on my form before any resizing takes place; I simply demonstrate that the problem gets worse when resizing here as additional information.

Auto-sizing Buttons In TableLayoutPanel

I have a form with a TableLayoutPanel with the following properties changed from default:


This is a stripped-to-the-basics version of part of my app. I want to generate a vertical, scrollable array of buttons which will allow me to select groups of photos. Each button will represent a group of one or more photos in a collection. The app will scan a folder and determine which groups are present, and which files are in each group. I create the buttons (with AutoSize), then determine the width of the widest button (at the same time, setting the button anchor property to make all buttons the same width. I then set the form to accomodate the width of the widest button.

C# - TableLayoutPanel GetControlFromPosition Does Not Get Non-visible Controls?

Aug 22, 2011

I'm using a TableLayoutPanel and I want to get the control at a specific position in the TableLayoutPanel. I want to iterate over the rows and columns of TableLayoutPanel but this question applies equally if I just wanted a single control at a specific row and column.Unfortunately GetControlFromPosition(int column, int row) only retrieves controls that are visible (that is their Visible property is set to True). This is no good to me as sometimes I want to access a control at a specific position that is not visible and then make it visible.

I have had to resort to iterating over the TableLayoutPanel.Controls collection, and then get the position of each control using GetPositionFromControl(Control control) or GetCellPosition(Control control) until I find the position I want.(I'm not sure of the difference between GetPositionFromControl and GetCellPosition methods as MS documentation is meagre, but I'll ask that question separately).

Dynamically Displaying Some Controls In A TableLayoutPanel?

Feb 17, 2012

I am dynamically displaying some controls in a TableLayoutPanel. The problem I'm faced with is that I want the controls to be displayed in a specific order, instead of just filling the TableLayoutPanel from 0,0 till the end of the panel.

I have 5 columns and 5 rows.

1st row is for buttons only, 2nd row for combobox, 3rd row for radio button.

I want it to be displayed like this:

Button1                Button2           Button3
Combobox1         Combobox2
RadioButton1      RadioButton2    RadioButton3     RadioButton4      RadioButton5

Expand Control Size In A TableLayoutPanel?

May 15, 2009

I have a routine which allows me to expand the size of my DataGridView within a TableLayoutPanel.  Effectively it repositions the DGV to the first row and first column of the TableLayoutPanel that it is in using the SetRow and SetColumn methods of the TableLAyoutPanel.  Then it sets the column and row span by passing the row and column count properties of the TableLayoutPanel to the SetColumnSpan and SetRowSpan methods. It work fine. There are two buttons on the form, One expands the DGV the other returns it to its original state.

My question is, how would I set this up if I wanted to do this for all the controls in this TableLayoutPanel and/or every control on every other TableLAyoutPanel on my form. I am assuming I have to use a class as I would have to create an abundance of public variables to pass the row/colum and row/column span starting positions to.[code]....

VS 2008 Autosize Tablelayoutpanel With Textboxes?

But if the user hides a column in the datagridview, I want the textbox below to disappear as well and the other textboxes automatically take up the empty space.

I made some screenshots so you will be able to understand it better:

When the user hides the column:

The column named "Totaal prijs" has now gone and so has the corresponding textbox below. But the columns in the datagridview now stretch nicely to take up the free space. How can I do the same with the textboxes?

XML Serialization To Save TableLayoutPanel's Contents?

Oct 5, 2010

I have used the XML serialization to save a single text and a picture in a XML file.However, I am confused on how to extend the concept further.I have a second Windows Form which has a TableLayoutPanel in which each cell has a Picture Box and a TextBox. The user has the option to set the number of rows and columns himself, so I do not know about the number of pictures that have to be saved in the XML file. Further, when the user pressed the load button, the same pictures have to come back to their original pictures boxes in the TableLayout.

How can I save the contents of the TableLayout in the XML file and retrieve them in their corresponding cells?
