Don't Add Value If Already Exists In Datagridview

Sep 28, 2011

I have a datagridview with two columns: name and str.

i have this inside a for loop:

DataGridView1.Rows.Add(namevariable, strvariable)

this adds a row in the datagridview.

sometimes the value of strvariable could be the same of a value that is already in the datagridview in the str column.

when this happens i dont want to add the row.

basically: if the value of strvariable is already in some row of the str column, do not add the row.

Search A Datagridview Column To See If A Value Exists First?

Jan 22, 2010

I am creating a program which searches saved .htm files for the source codes. I get the source code and do manipulation on the code to pull the values I need into a datagridview.

Is there anyway to search a datagridview column to see if a value exists first, so no duplicate rows of data will be added? I was thinking of making access table and linking the datagridview to it, but i'm not sure how to set the database links up with code (other than the gui), and then still search the column so I don't put in duplicate rows.So far, I have only come up with the way to add the data row by row...

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim IMsku As String
Dim IMskuitna As String

IDE :: Use Sql To See If Record Exists In A MSAccess Database (without A DataGridView)

May 30, 2012

I'm updating an app for children I wrote in VB6 to VB2010. It uses a rather extensive MSAccess Database. It works perfectly but I need to update it to utilize better speech technology. I have read a lot about SQL and can't find how it is useful for anything accept business applications that add, delete or update records as long as you hard code in a name. I don't use datagrids and I never display a table. how to do a few things, I can figure the rest out.

In VB6, I had:

Option Explicit
Public db As Database
Public rs As Recordset
Public Reader As Recordset

Check If URL Exists?

Jul 10, 2009

This is the standard way of checking if URL exists [code]....

return true; } catch (Exception ex) { return false; } But my problem is that we have to check it for around 100 URL's. It takes more then 2 minutes to check for all as it is trying to get response of all of them. Is there any way that we can check if URL exists without getting complete Response so that total response time is less.

How To Verify If Value Actually Exists

Feb 10, 2011

I've created a little procedure that I use to verify if a value does actually exist. I'm currently using this all throughout my application for things such as verifying if a control's EditValue actually has a value. I was wondering if I have missed any scenarios where a value would not be available, missing, non-existent, blank, etc., and how would I incorporate in my procedure.

Try
ValueExist = True
If IsDBNull(CheckValue) Then
ValueExist = False

.net - Row Doesnot Exists In DB- Exception?

Oct 25, 2010

We have a dataset dsActualCost which fetches query value: MonthName in one column and Cost in another.We have a code to display data in table format.

For MonthIndex = 0 To dsMonth.Tables(0).Rows.Count - 1
Dim tdMonthlycost As New TableCell
If dsActualCost.Tables(0).Rows.Count > 0 Then[code]....

This code works fine when,we have data in all rows.we have no data at all But it gives exception for all other cases.I tried to debug and issue arises when it searches for any row which is not available in DB. Say the dataset has only 2 rows for Feb month,so when it executes line

IsDBNull(dsActualCost.Tables(0).Rows(2).Item(1))

It throws Db null exception.

Asp.net - Check If Referrer Exists?

Jul 25, 2011

In my code, I want to check if a referrer url exists and if the referrer url contains a specific sub string. I know how to check for the sub string:

If( InStr( Request.UrlReferrer.ToString(), "some sub string here" ) > 0 ) Then

But I don't know how to check if a referrer exists or not. No refer exists if the url is entered in manually in the address bar. So I tried this, but this does not work:

If (Not (Request.UrlReferrer.ToString() = "")) And (InStr(Request.UrlReferrer.ToString(), "some sub string here") > 0) Then

how do check if a referrer exists?

Asp.net Mvc - Getting String Value When Delimiter Exists?

Oct 18, 2011

I am working on finishing up a mvc 3 vb.net app... I have to parse about 2000 entries in a database and get the string value to the right of a " : " delimiter from one of the columns... Everything to the left I am not worried about but I need the value that is to the right of the colon for that item.. I have more issues involving needing to select string characters to the right or left of a delimiter... But if someone can show me how to achieve the above I can figure out the rest from there...

a example of the string is Jackson Smokehouse Fish Food:John Jacob JinggleHimer Schmit I would want to eliminate the first part of the string or just select the second part and put it in a variable for later processing...

Check If Permission Set Exists?

Mar 17, 2010

I am using Caspol.exe to install a custom Permission set and add Code Groups for my .Net 2.0 Windows Application.

I have created a Console Application that uses caspol.exe to add Permission Set and Code Groups. I first install the Permission Set and if I do not get an error, I continue to install the Code Groups

Now sometimes I need to add a new Code Group to the client machine, so I make the changes to the console app and it is executed on the client machine. If the client machine already has the Permission Set installed, it returns an error and stops the further processing.

So, I want to know if I can check whether a custom Permission Set is already added or not?

Check If SQL Record Exists

Jul 19, 2011

I have a small database. 2 main tables called CaseDetails and Checks.Each record in CaseDetails can have 3 checks recorded against it in the Checks table. But can only have one check of each type (check types 1, 2, 3).I have 3 linkbuttons which will take the user to the input form for each 'check'. If a 'check' already exists i want to hide the linkbutton that takes the user to that 'check type' input form (the 3 input forms have different fields).So what i need to do, is connect to the SQL database and see if a record exists for each 'check type' and hide the linkbutton to prevent users from entering another record with the same 'check type'?I have tried reading the reults into an array and examining that array, but havent been able to do so.
