My program creates a dynamic table of information, Im trying to simplify some of the information by using a loop. To make it easy I will just say that the table starts on A1 and goes to (columnindex:rowindex*6) (that part is already done).

I have an Access 07 database I'm using to store my data. I have no problem at all filling a worksheet in excel or a table in word from the textboxes currently on the screen and saving it as a pdf. That's basically how I'm reporting my data from my program.
Where I'm stuck is how can I do the same process for each row in my dataset that has a date or value similar to a filter? I can filter the dataset by adding a query in the dataset designer so it only displays the rows I want to build form reports for, but I don't know how to code a loop to make it work for each row.
Basically I'm looking to find a way to print and/or create pdf form from one button click for multiple records and not just the one currently bound on the screen.
How would you take a numerical input from 10 text boxes and total it up and send it to a label. Then average the 10 numeric text boxes and send it to its own label. I am not asking for any code, I just need a hint or two to jog my memory. If this is not clear for you, I'll provide more detail.

View 4 RepliesI am relatively new to the world of programming and I was wondering if anybody could help me with a small project. I am trying to create two programs in VB.Net that each do one of the following individual actions:Find the average grade given several user-inputted scores on assignments. The program should also provide the following feedback according to the final score (i.e. A, B, C, D, F).Run two separate threads printing numbers (or words) in ascending and descending orders. (The numbers (or words) should be given by the user.)I have a basic understanding of VB.Net, but I am having trouble when it comes to creating even remotely complex programs. I have a few ideas on how I may go about these, such as using an arraylist for the first question that takes user input to find the grades, and then uses a series of If-Then-Else statements to display the letter grade, and possibly using steps simply with dual threading that would result in numerical order being printed in ascending order and descending order.

I am working with a folder of xls files that are all in identical format (automatically generated by entering numbers into a pricing app). I need to pull the data that is in cell D54 on the worksheet of the same name in every file. Can't seem to get anything to work to make it loop.

Here is what I have so far.

I am trying to save details from my program into a sort of mini database using excel, my program isnt having a problem opening the excel file, it is having trouble inputting the data. The first problem i would like help with is maybe a loop of some sort to get my program to look through each line on my excel spreadsheet and find the next empty line so it can input the data.
I was having some help from another person who gave me some code which go's to the very bottom cell and goes up until it finds text and then off sets by 1. However this was in the form of a macro, and I need a way to do it from my program.

View 1 RepliesI am working on trying to update a list of items to an Excel spreadsheet. I have created my own custom class called Songs and a List(Of Songs) that I want to update the spreadsheet with. It seems like everything is working -- I have even put in a debug msgbox that displays what Song it is currently on while iterating thru the loop -- but after the code iscomplete, I check the spreadsheet and only the first song in the list gets updated. I'm thinking it must have something to do with either the connection string or the parameters that prevents it from updating any other song records. BTW, there is no errors being tossed so it ats like it everything is being processed, just that the data doesn't change for the update inside the loop. Here is the section of

I'm using VB.Net's Excel component to read Excel file, but the performance is totally slow, since it has to loop through cells to get values. Reading a file containing one sheet with 1162 rows and 105 columns (which is small size compared to my general requirement) already costs more than 5 minutes.1. I want to ask if any of you have suggestion on reading such an Excel file with better performance, except OleDB, cuz most compies here have vesion problem?2. Is it normal that it tooks a long time for Excel component to read Excel file, or is it that I implement the code in a wrong way?

I need to import a .csv file so that it formats it all nice-nice so I can easily get the information from a column or row, then I need to grab certain rows, then reorganize it and save it into a different Excel spreadsheet for the program to then use. The original .csv does not contain the information in a way that we need it to be.

Makes the following statement about the code below:
**"The computer evaluates the loop condition in the Do...Loop statment to determine whether the loop instructions should be processed. In this case, the inputsales <> String.Empty condition compares the contenst of the input sales variable to the String.Empty value. As you know the String.Empty value represents a zero length, or empty, string if the inputsales variable is empty, the loop condition evaluates to True and the computer process the loop instructions. *If on the other hand the inputsales variable is not empty, the loop condition evaluates to false and the computer skips over the loop instructions.
Based on the code I think it is the opposite: ...that while the inputsales value is not empty it should evaluate to true and process the loop and if it is empty it should evaluate to false and skip the loop?
See below.

I am currently working on a project, which purpose is to call a webservice through a VB script. VB is by far not my first language and I simply reach the point where I do not know how to go on from here.
I have a Webservice descriped in a WSDL document that defines a service that takes a complex type as parameter and returns such one as answer.
The complex type is basically just a string that is wrapped inside a class object. So what i did was to create a new class module and added a public variable to it. I created a new instance of this class, gave it for the purpose of testing a value and tried to call the webservice. Everything goes well untill i reach the call to the webservice, where the program throws an exception that says:
"Class does not support automation or does not support expected interface"
My first thought was that the initialization of the object might have gone wrong but i am quite able to set and get the values on it. So i have to assume that the object is okay. I know that the url to the WSDL document is correct, due to the fact that I can call the document via the browser and it will throw an exception of "wrong type" when i feed the soap method with a primitive.
With out luck I browsed several pages on the net to find a clue what this could. So now i wanted to give this forum a shot.
You should know that i am not able to alter the WSDL file. I have to go with the way it is. In addition am supposed to stick to VB 6.0.
I used a Form in VB to make the call to the webservice.
Here is the call procedure:
Private Sub Command1_Click()
On Error GoTo ErrorHandler

I have a custom modelbinder built to handle my accountRequest class.This class consists of some boolean values and a UserViewModel.The UserView Model is made up of strings such as Firstname, Last Name, Address.Originally I was just passing the UserViewModel as the action parameter but I now I need to package UserViewModel inside of accountRequest.however, now my modelbinder will not map the strings in the httpContext.Request to my UserViewModel inside of AccountRequest. All of the booleans map just fine.Is there an easy way to get his data to map to the UserViewModel properties other than hardcoding it? [code]
View 1 RepliesI'm trying to save some settings in a complex object. If I make a dll of the class I can then add it in the projects properties settings list as that type.When the program runs though it won't show up as anything other than nothing. I read you have to have a sub new empty constructor which I have but don't know why else this would fail.First question is how to you do this. Second is there anyway to use a class inside the project as the target of the settings type or do you have to bring a in an external dll to do this every time? [code]
View 4 RepliesI suppose this is more of an opinion question, but, when you start a big project, what do you think about before you even start Visual Studio? Do you setup structure and files before actually coding them, or do you code them one-by-one?
