Get Values From A Column And Put Them In Another Part Of Program?
Nov 15, 2009
I am working on a program where the user inputs values, then the program calculates those values and outputs the sum. When the user hits the button exit then those values entered by the user are saved. When the user starts the program again, the values are still there. I wrote the code and everything works fine. I am saving those values in notepad... and the program grabs the input in notepad and outputs those values to the program. But here comes the problem:
Lets say the user wants the information in a certain column to be added to another column somewhere in the program. Is that possible ? And if it is can it be done when I am saving those values in notepad ?

I was wondering can you get a program made w/ vb to click on a certain part of the screen outside of the program? and also, can you copy information from outside the program in another window and store it in the program as a variable.

Im trying to make a fast food program on which the user will input the amount that he has, then he will click on what he wants, by using check boxes. There are 7 different check boxes with 7 different amounts of money. I got an idea on what to do (they will check on what they want and the program will add up the total and there is only one of each item), but im confused on how to put the amount on where the check boxes (in the program area and not the text area) and add them together. After that all I need to do is add everything up, with sales tax, and tell the user if he has enough money or not. But what im confused on is how do I get the check boxes to a amount of money and add them up (all the ones hes checked) I just dont know how to code this part of the program, once I get one done all I have to do is the same for each one, and everything showed be easy after that. But how do I put an amount on a check box and add them all up?

Have a program that collects response data as part of a psychology experiment and i want the output text files to show up on the users desktop so that they can find them easily and e-mail them to me. I'm using Parallels on my Mac to run windows XP and found the files in a desktop folder but they were not on the desktop. Am I coding this right?

im making an application in vb.net (duh!) anyway i have created and coded the whole project and it performs exactly as i want it to (i dont need code help). my problem lies with the fact that my project is 2-3 parts
1.a setup form that gathers inital data about the enviroment stores this data encrypted in a config file. after inital setup this form is not displayed again. but needs to be run on both computers
2. the second form is the real application form im in the process of turning this part in to a background service anyway this form is the one that establishes the connection between two nodes it works correctly
3. the config files
anyway here is my problem i want to make this application distributional with just one file the (.exe) and have this .exe make everything else happen. it runs the setup form and creates the first config file which it does then it needs to produce a copy of just the second form and the config file to transfer to workstation #2 that will run independtly without the whole application which i cant make happen then it needs to turn both workstations application on by only starting one on either computer and invoke the other computer to start its corrosponding app also no idea how to make this happen any ideas or suggestions as to where to look to try to find my answers.im thinking i might need to make two seperate applications (a setup app, and the running app) and include them both in a project and use the setup.exe to to package them together this is a little side project that im making for my self to use to make programming a little easier so i plan on giving it out to some fellow students to test and tell me what they think so im not really worried about ease of use or complicated procedures yet but if it turns out to work and actually be of use to anyone else i would be willing to rewrite it to distribute to the masses but for now i just want it to work for me.

I am using a Webbrowser in my program.
In the page source of a certain URL is the following: <input type="text" name="email" maxlength="50" value="email@email.com">
I'm trying to get the value part from the source and have it printed out to a TextBox on my program. I'm not sure how to do this but I tried. I made a new HtmlElement called email. Then I did email = WebBrowser1.Document.All.Item("email") However, when I try to add it to my textbox it doesn't work.

I have the following worksheet:
Quote:
SEP138 F-001-13, 8kV
SEP138 F-003-13, 8kV
SEP138 F-004-13, 8kV
[code]....
I wonder if anyone knows a macro developed in Visual Basic to separate the first part "F-001" to a different column
example:
Column A = F001
Column B = Sep138-13, 8kV
The spreadsheet is quite wide, going up to about F-220 I could only get to it:
StringElement Function (str As String, chr As String, ind As Integer)
As Variant Dim arr_str
arr_str = Split (str, chr)
StringElement arr_str = (ind - 1)
end Function
is very simple, just separates into single column and not the entire worksheet?

I have a table called Table1 which already has a few other columns and 4 rows. I want to add three new columns to it. When the columns are added I want all the cells in the column to equal the variable I supply in the Add method. When I add the column named "BatchID" it works beautifully, but when I add "UserID" it gives an error "Cannot find column [iqz9]". Why? This is how Table1 should look like:

I have a database and a dataset as the image shows in the link, how would i add the values of the colums "amount1" and "amount2" for every row and entry as the user make entries to be automatically displayed in the "total" column. Meaning that every time values are entered in those amount columns, they will be added and the total displayed in the "Total" column.

I have a databound DataGridView and use a button to control updates.
The problem is that if a db Column does not allow a null value an error is thrown ("Column <ID> does not allow null values") and then the datagridview automatically removes the row. This error is raised as soon as the user leaves the cell and before the update command is issued.

I have a db with Column name Break. I have attached to my datagrid view and all that works and shows up correctly. However Im needing to put this code in a timer to get all the times in the Break Column but I need to get it from each and every row. For example:

7:00am
6:30am
I need it to look through each row and get that value. Ive tried various things, but Im not on my normal computer so I cant post my code.

I have a a few checkboxes that I want to be checked based on a value of columns in a table.So I have a table that has a date column and I run a search based on a particular date. Then I want to be able to go through the rest of the columns based on the selected date. But I need to be able to check individual values. Not sure if this is making sense. It is for a checklist. I want to click on a date, and it will auto populate checkboxes based on what was pulled from the db.

I need to find rows in resultsets that have every column without null.these resultsets got variable number of columns.currently, the only way that I can think of is creating a view on each resultset and filter this way:
select field1, field2, field3, field4, ...
from "huge query"
where field1 is not null and
field2 is not null and
[code]....
and then in a storeproc/function or .net code(c# / vb.net) loop through all rows / columns and flag or remove every row that got any null?
