Select All Used Rows And Columns And Display As Text?
Nov 24, 2011
I have this function that i created below, this function gets all values in each cell of excel, but i do have a problem with this because its taking minutes to display the text from each cell, is there a way that i could make a function or call a excel method or property to get all values in a worksheet and put it in a string so i could display it or store it in a single column in our database.. actually our main purpose is to store all data that we could get into the database for reference and search criteria.[code]...

For a project i am working on, i am taking bookings. These bookings are stored in a database alongside a users personal details. The personal details are assigned an ID according to the user who booked it. A user can book more than once with different personal details.
My problem is that i want a user to be able to edit a booking. I want a list of all the names that user booked to be listed in a combo box. This is the part i am having trouble with. i am using an access database and using sql statements to pull out the data. This is what i have tried so far:
SELECT [First Name]
FROM PersonalDetails
GROUP BY [First Name], UserID
HAVING (UserID = ?)
If i execute this query in the query editor, it works and shows the two records currently assigned the input id. However, if i try to output this to, for example, a text box, then it remains blank. I am assuming thisis because there is more than one output, but i'm not sure.

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
b
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.

I have Dataset ds filled up with values Until now I was displaying values in GridView. Now I want that all the rows should be columns and columns should be rows.I have 2 options: Either 1 I can directly convert grid to columns and display it, or 2 I can convert the GridView to html and then write loops to convert. I was trying the 2nd option but I cant figure out how I should do that.[code]With this code I am still getting same as GridView. Please help me for converting rows to columns and vice versa.

I made a form with text boxes in a 6x6 square pattern. It will do a streamreader from a text file a number that indicates the size of the array. Then fill in the boxes with the numbers of the array. Then it will calculate the rows and columns to see if they add up to a single answer. Then it will display to an output window if it is a magic square or not. Meaning if all rows and columns add up to a single number its magic. If they dont add up to the same number then its not magic. Then it will repeat this check and output from the information of the other arrays from the text file.
I know how to code for the streamreader and get it to add the rows and columns. Im not sure about what code I need so it can check the answer if its magic or not and repeat it till the end.
Here are the contents of my text file which it will read from.

I'd like to display 2 columns of text.Is there a better way to do this than
for line: drawstring (text @ column, ypos + (line_inc * line)) ?
I thought Visual Basic would be less tedious than the SDK in terms of having to do things by coordinates. Designing other things on the form, for instance, would be awkward since there is nothing to indicate the boundaries of my columns.

I am stuck on how I go about using the nested for loops.Add code in the Draw button�s Click event to create the number of rows and columns selected, using the character selected Use nested For loops to create the rectangle of characters based on the user selections. The outer loop will control the number of rows. Use the value selected in the Rows combo to determine the stopping value of the outer loop. Use the value selected in the Columns combo to determine the stopping value of the inner loop, which controls the number of characters per line.

I'd like to copy some rows of data from a data-bound datagridview to a different datagridview.I thought adding a row would just be like this: [code]The trouble is that, instead of copying all the data from the row and putting it in the correct cells in the other datagridview, it seems to be taking the whole row object and putting it in the first cell, so the first cell contains this: [code]And the other rows are empty. How do I make rows copy properly?

I am using Datagridview to show some table data from database. It is working but its appearance is not what i am looking for. Is there a way to edit columns and rows manually ?
This is a list of what i want to do :
1. First of all i want to change column captions. because they are like "Fld_name" etc.
2. There is a column that shows date. I want to write a code for it ( convert date type )
3. I want to add a button at the end of each row and write a code for it ( show detail about that record )

how to print, and got it working pretty well. The text string I have printing into a rectangle, and if a word does not fit it will wrap down to the next line, and then keep going like that, but now I need to split my page into three different areas that will each print different text.I am pretty sure I could draw three different rectangels then draw the text I need on each of them, but is it possible to somehow merge them together into a single rectangle that will be printed?

I have divided the circle into rows and columns and each block(square) formed in the circle is of equal size. I have the X and Y co-ordinates of each square/block. Each block is either defined as good or bad.
Problem: I need to add 2 blocks on the same row and determine if the result is good or bad. If any of the block is bad, the group of two block is called as bad. If both are good, only then group is good. what would be the algorithm for it? I need to do in visual basic language. Also, I need to do more cases like adding 3 blocks and determine if the group of 3 block is good or bad. In this, if any block is bad, the whole group is bad.
Update: When I divided the circle into rows and columns i.e blocks, I remove the blocks that are not in the shape of square. That is, those square/blocks which are touching the circumference of circle are deleted. I can upload the photo tomorrow now.

I want to change the row color of every row in my DataGridView where a particular column value = "RBF3". I am currently using the DataBindingComplete event which seems to work fine, but it fires every time I change a cells value. I'd like for this bit of code to only fire when the datagridview is first displayed, sorted, or filtered. Is this possible?
