Counting The Number Of Rows In A Database?

Apr 30, 2009

I am using a tableadapter to connect my project to an MS database. I need a a function which counts the number of rows in the table for something which I am doing. I have sucessfully used the count function to count the number of rows for my other tables, but when I tried to reuse it for another table, it wouldn't work. I get an error...

An unhandled exception of type 'System.ArgumentException' occurred in System.Data.dllAdditional information: Input string was not in a correct format.Couldn't store <AH25> in ProductCode Column.  Expected type is Int32.

and this is the code which I used

Dim record As Integer = TAProduct.GetData.Rows
Do Until record = TAProduct.GetData().Count
' other codes
loop

It only seems to work if the first column is an integer datatype, which is the case for my other tables, but the table which I am currently dealing with using a string datatype. Is there another way to count the number of rows without using SQL statements or can I adapt my existing code in some way?

Filtering Rows In A Gridview?

Apr 4, 2012

I have a gridview that contains user info and one of the columns is a date when the user was added to the system. Is it possible to use the GridView.onRowCreated method to check if the user was added within a given time frame? If the user was added within that timeframe, then the row is added, if not, then that row is not added.

Note that I can't modify the datasource of the gridview, so I need to do this somehow as the gridview is being created.

Counting Rows / Columns In Excel Worksheet Using VB 2008

Mar 16, 2012

This is my first time posting in a forum like this, so please excuse me if I accidentally break any thread rules (btw, where can i find these?). I am very new to Visual Basic and have been trying to teach myself as I create this program. I have experience with macros in excel so I do understand some of the coding, but definitely nowhere near being proficient. I am using Visual Basic 2008 Step by Step (Michael Halvorson) to teach myself.

I am trying to create some code in my program that will allow the user to open an excel file and then return the number of rows and columns in the worksheet. There will only be 1 worksheet in the workbook (since this is just a small part of a larger program I am writing). I already tested the code that will open the file in another program and it worked fine; the thing that is catching me is the row and column counts. I'm a bit stuck here and was hoping someone could point me in the right direction. Here is the code as follows: Code: I have another sub for a quit button which I chose to leave out. The last line for the MessageBox is causing me problems.

VS 2008 (DataGridView) :: Delete Successful Inserts Of Rows And Move Rows Up?

How would i delete only the successful inserted rows for insert and then move the non successful rows up and allow the user to correct the data and get it ready for an insert. If i dont delete the successful rows then i will have multiple inserts of the same dataRow and we dont want that! AND if i dont move the data up then it will have blank rows uptop and will end the try and not insert the corrected data. You can better see what logic i am trying to perform at the bottom of my code, right after I insert into the database. Here is my code.

VS 2010 : Combine Similar Rows In A Datatable (the Rows Only Differ By One Column)?

May 8, 2012

I have three sub tables that I want to process. For each I want to combine the rows, as they are only different by contents in the second column(I want to do the same to the fourth column, later):

'Sub table 1
xx|C201 |02300877 |Samsung |....
xx|C201 |02300877 |Toshiba |....
xx|C213 |02300877 |Samsung

p.s. For the fourth column, Manufacturer information , I want to do the same and I'd probably get something like this for the final table:

xx| C201,C213,C606,C619 |02300877 | Toshiba

Accessing Specific Rows And Information From The Rows Using VB In An Access DB

Mar 23, 2010

Public Shared Function isMatch(ByVal username As String) As Integer
For i As Integer = 0 To table.length - 1
Dim cellValue As String = table.getRow(i).getCell("Alias")

[Code].....

I have the code listed above as a translation from a Java snippet. The problem i have is that in Java, my table was stored as a dataset and as such, the methods were easily identifiable by "getRow" and getCell" using specific numbers and column names. However in VB the information is stored in an MS Access database (which i already have an open connection to, called: "_SalesPerformance_AnalyticsToolDatabaseDataSet12") and as such i do not know the correct way in which to iterate through each row in the database, checking a specific column against an already specified variable and then returning an integer based upon the value of a seperate column in the same row.

Counting Instances In Bindingsource?

Mar 7, 2012

Is bindingsource.count only used to give the total items in a list? I'm trying to prepare data for a pie chart, and need to count the instances of different items in a column (If there's a way that the Chart will do this itself, I've not been able to find it, it seems to need linked items and values). The bindingsource is already filtered and would prefer not to combine filters.Would it be best to loop through the rows of the column and count them 'manually' or is there a quicker way of doing this?Put it in a datagridview? Is it possible to use Aggregate Count on a bindingsource?

I would like to know how to count specific characters for a proper split value so I can seperate the name of the file from the rest of this address:

C:\Program Files\Folder\Folder\File.file

The reason is so I can combine it with other addresses taken in my code to cuase a proper copy command using the File.Copy with import IO The character I am trying to count is: \ This is so when I command the split, I can choose the split number (starts at 0) so if there are 4 of the "\" characters, then I would subtract one from this number, and use it as the Split index so I can capture the split data at: File.file

Making A Counting Program?

Oct 5, 2009

I am making a program that is very simple, but I'm have problems with it. It runs like this:Theres a textbox and you enter in any amount you want.Next to that there are three radio buttons, deposit, check and service charge.If you enter in 100 in the transaction text box, and check the deposit radio button, and hit "Calculate" it will display 100 (in a total display box); hit calculate again, it will display 200, then 300, etc..Now lets say you keep 100 in the text box, but you check either "service charge" or "check" and hit calculate then it will MINUS the amount in your total display box. So for example if you had 300 in the total display box, and 100 in the transaction box and you checked "Service Charge" and hit calculate it would display 200 in the total display box, hit calculate again, and it shows 100.. etc..

VS 2008 Counting Down From 30 Mins?

Feb 7, 2010

I've done what I thought was a lot of work with DateTime and Timespan but what I am trying to do now I cannot figure out. It seems simple enough but I can't think of the code I need to make it work >.<

Currently I am using a timer to tic on 1000ms to count down a timespan. However, what I would like to do is set a timer for 30 minutes. I would like to display the minutes:seconds of the timer on a label and perform actions when the minutes and seconds are specific values, say minutes = 5 AND seconds = 0 to perform an action when the timer reaches 5 minutes exactly.

My goal is to have a 30 minute timer that performs actions at specific times, then when the timer reaches 0:00 it restarts at 30:00 This seems like such a simple task but I cannot for the life of me figure out where to start.
