Looping Through RTF Box With Tabular Data?
Feb 22, 2012
I need to be able to copy and paste data from a spreadsheet that may be an .xls, .xlsx or .csv into my app. Then once the data is pasted in I need to do some parsing and saving to an Access database. So I put a RichTextBox control on my form and put the following code in a command button to get the data into the textbox. Will this work as is to allow me to get to the values? And if so, can someone show me a little snippet of how I can get to the values? And if this approach is wrong, then how do I go about this?

What is an alternative way of presenting tabular data aside from DGV? I tried DGV but i cant seem to populate the DGV automatically using datasets. Is there a way to manually place my data on the DGV using the read.Item("column1")?

I am currently developing an application that will require each end user to specify a rather large set of tabular data specific to his/her own preferences. Each time the user starts the application, it will load this set of data.
what is the best way to store this data locally on the end user's local machine? Should I use XML, Access mdb, flat text files?

I'm really hoping I can describe this question in an understandable way. This is a puzzle that I have not been able to begin to solve even though I (mostly) understand it. I'm just not sure where to start, and I'm really hoping someone out there can get me headed in the right direction.
I have a LARGE table of data. It describes relationships between objects. Let's say the Y-axis has items numbered 1-1000, and the X-axis has items 1-1000 also. If item #234 on the Y-axis is related to item #791 on X, there will be a mark in the table where the row and column cross. In some industries this is referred to an a Truth Table. One can, at a glance, see how many items in a system relate to each other. The marks in the table can help to identify trends and patterns.Here's some other helpful stuff about the nature of the table:
The full range of the number of relationships (r) for each item on either axis can be 1 <= r <= axisTotal.The X and Y axis will share common items, but each axis will also have items that the other axis does not.Each item will only exist once per axis. It can be on X and Y, but it would only be on each one 1 time.The total number of items on each axis will most likely NOT be equal. Each axis could have from 50 to 1000's of items.
The end result is that this is going to be a report that needs to be printed. We have successfully printed a table that had about 100-150 items on each axis on an 11in X 17in piece of paper. Any more than that and it begins to be so small it's unreadable.
What I am trying to do is split the super large tables into smaller tables, but related points need to stay together. If I grab item 1-100 on X then I would need each item they relate to from Y.I've generated a number of these tables and, while the number of relationships CAN be arbitrary, I have never seen an item relate to all other items. So in real practice the range is more like 1 <= r <= (10% * axisTotal). If an item's relationships exceed this range, it can be split up into multiple tables, but that is not optimal at all.
At the end of the day I think we, and our clients, would be happy if a 1000x1000 item table was split into 8 to 10 printed pages of smaller, related tables.One other thing worth noting, there will be no empty rows or columns in the table. Every item on both the x and y axis will relate to at least 1 item on the opposite axis.

I have a csv file with data in it in the format...
EVENT|RUNNER|ODDS
1 - 2 - 1
1 - 2 - 3
1 - 2 - 5
[Code].....
So basically the data contains events, runners and odds. I'm looping through and assigning the variables to the relevant object propeties, alls fine.
The problem comes when I'm checking the next runner id (or event id) to see if it's changed so that I know to create a new object. Well in checking that the id has changed I've already moved one record too far so every time I'm changing to a new id I'm losing one record.

Is there a way to save either an array or list of data to excel without looping through the array/list? I know I have read from Excel this way but what about writing? Seems it would be faster.I'm collecting data from a device and storing into a list, then I copied it to an array getting ready to blast it in a single shot to Excel and got stuck.

When my application loops through the first code block below, I get valid data for all datarow fields. [code]...
But I get an error when looping through that code block "Collection was modified; enumeration operation might not execute." [code]...
However, in the second code block, I get a valid record for MgrID, but I get a blank value for the other fields.
When I look in the database, all fields in that table have valid values.

For example
month1 month2 month3 total
district1 5 2 9 16
district2 1 0 11 12
total 260 150 140 550
Here final total is not much important. But at least I need to show count per district per month.
SELECT Districts_mst.district_name,COUNT(Payments.PaymentId)users ,DATEPART(M,payments.saveon)Month
FROM Payments
JOIN Subsciber ON Payments.SubId =Subsciber.SubId
JOIN districts_mst ON districts_mst.district_id = Subsciber.District
where lang_id=1
group by district_name, DATEPART(M,payments.saveon)
Which give me list like.....
district_name users Month
dist0 1 1
dist1 1 11
dist2 3 11
dist3 1 11
dist4 3 11
dist5 1 12
dist6 1 12

Currently I have a problem with updating my database with values in my Data Grid View.
On my form I have a "Populate" button and "Submit Details" button.
The "Populate" button fills my Data Grid with numerous lines of data.
On the click event for "Submit Details" I want this data to be inserted into a table in my DataBase by looping through each record.
For Each dgi As DataGridView In DataGridView1.Rows
Dim productCode As String = DirectCast(dgi.FindControl("product"), Label).Text
Dim description As String = DirectCast(dgi.FindControl("description"), Label).Text
Dim quantity As String = DirectCast(dgi.FindControl("order_qty"), Label).Text

I am using datarepeater to display rows of information from database. When i click a 'save' button and i would like to loop through the rows of data in repeater. The code i am using is able to do all these. The only problem i encountered is at the Interface side. When i am looping the data-repeater. The selection 'frame' (refer to the picture point as 'A') is moving from record to the next record and scrollbar is auto moving as well to scroll to further down until the last row where looping finish.Is there anything can be done to remove the selection 'frame' and stop datarepeater from scrolling while looping the datarepeater.

When I debug and click space down, my picture box of the knob slides on down to 175, pauses, and shoots back up. The problem I'm running into, is that it doesn't do anything if I try to pull the knob down again. It doesn't bug out or anything, but it just doesn't do it again

I'm trying to write a program right now for my computer science class for a program where you insert text into a text box, (the text being a password), and then click a submit button. The goal of the assignment is to have a program that looks at the user given password and see if it matches the const password (or one of the three const passwords in my case). If it doesn't, it is supposed to loop back so you can re-input the password. Also, If you enter the correct password, the loop ends and you are to get a msgbox (or, in my case three different ones), and then the application closes. We are to write the code so that if the password is wrong "x" (insert 3 as the number I have chosen), a MsgBox will pop up with a message saying
something along the lines of "you have gotten the password wrong to many times.", and then the application is supposed to close. I don't think I could rant on much more, I've done a good (or in my eyes terrible) job of summarizing the assignment.
[Code]...
My problem (aside from, I don't know, a problem with my code itself) is that when It reaches the loop, it goes through all the code again, but I'm unable to change the user given password, and so it just pops up the three failed password entry MsgBoxes (the code for which is temporarily removed), then the failed to many times MsgBox, OR one of the successful message boxes. What I'm wondering is if anyone can help me fix my code so that it functions as desired.

I need a loop to run in the background while my app. is running. The loop has to constantly check for the value of a var and return a value based on the values of the var.
Can a Loop be running constantly without slowing the PC down?

On a form I have a series of 20 checkboxes (cbS1 through cbS20). With that I have an integer named 'Count'
What I need to do: When the forms loads it will get a value for Count. I need all the checkboxes that are greater than this value to be checked.
So if count = 7 then cbS8 through cbS20 will be checked.
Im not really sure the best way to code this is. I know I can do it with a giant case statement...but there has got to be a better way right?

This is for .net frameworke 3.5 and visual studio 2008 in VB.Net.Two things we would like to do: 1) loop repeating node blocks 2) loop (through repeating node blocks) within repeating node block loop
First thing:
How do you loop through an xml that has repeating node block (<STRUS name="1000A") and extract the following node? For example you want to extract the IdentificationCode in the node that has <SVALU name="ZRT" and is from pos="9".So, the following example has the IdentificationCodes (TGJ23, PGA12, TPX12)
<?xml version="1.0" encoding="UTF-8"?>
<DocSplitterReport xmlns:xsi="http://www.w3.org/2001/X .......
<STRUS name="ROOT" lineStart="-1" lineEnd="-1">
<STRUS name="TAC" lineStart="1" lineEnd="194">
<SVALUs>

I have an array structure called Survey and I'm attempting to loop through all the data and get it printed out. I'm trying to follow the example in my text but I must have something different.Here is my basic structure:

Dim ID_Code As Integer
Dim Members As Integer

I'm not understanding how to fix? The objects and properties to the right of "Family Size: " are getting errors saying "Value of type Integer cannot be converted to System.Drawing.Font.
e.Graphics.DrawString("Family Size: " + Home.Members, PrintFont, Brushes.Black, HorizPrintLocation, VertPrintLocation)
