My Application uses For...Next loops to read a spreadsheet into a DataSet and then display information from it based on the results of search conditions (search term and a date range).I'm having a problem with the data where, if I run a search that should return the first 400 rows in the spreadsheet, I'm only getting around 200 results. I know the search should return the 400 rows because I checked it in the spreadsheet before running the search.I think my problem might be caused by my date comparisons. I think the problem might be that I'm comparing String valueHere's my code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If ListBox1.Items.Count <> 0 Then : ListBox1.Items.Clear() : End If
I have been looking for some syntax online to help me do this, but i cannot seem to find anything. I am trying to move some rows from a table in an access database to another on a click event handler.
One of the tables names is "Basket", and the other is order.So far i have this.
I have two datatable that I pull information from a db. I have a complicated form, and I have found it easier to write a simple SQL statement to pull the records. I have then used other controls on the form to trim the info down even further. When a particular falls out of the secondary control it is then deleted from the datatable.
I am then going back through the datatable and performing other actions on the datatable. When I narrow the information, sometimes I'm getting a DeletedRow is inaccessible. I have been looking at a way to do an IF statement to see if a row has been deleted, but I haven't figured out a way to skip a deleted row. Is there a way to skip a deleted row that I'm not seeing.
I have a for each loop in vb.net for this particular example there are 2 items in list but after the first item the loop exits are there errors in the code [code]
I have a problem saving a dataset which contains rows that i have imported from another dataset. i can successfully view the imported rows in a gridview but i cannot commit the rows back to the database.
I have two Datagrids, One grid has all the customers garments on it with style number and contact length. The other grid has the users who have garment issued to them. the style number is in both grids. I need to loop through the users grid and say if the contract number is 1 from the first grid then the contract date on the second grid will be todays date + 365 days (year contract) I have looked at using a stored procedure and also a for each command but I am just getting stuck with it all. [Code]
I have a parent/child relation I am trying to create fow 2 datasets.The parent ds consusts of a range of PO Header information
After I fill this dataset I loop through it getting the PO number. I then take that value and execute another sql statement on the DETAIL file and fill a dataset(dtlDS) for EACH row in the parent. How do I add to this dtlDS for each row? I am getting no CHILD data in the merge. Should I be filling to a datatable and do an add.row and THEN dump into the dtlDS?
I have a model that returns a dataset to a view and builds a list. The crazy thing is that I have tested this code with IE, Safari on Mac and Windows, Chrome and Opera and all return data. However, on the iPad or iPhone, zero rows are returned from the dataset object. It seems that the model is in fact passing the dataset to the view. I am using jquerymobile to render the view for the iOS devices and have taken that out of the mix to test and it still doesn't work.
how can I test if a dataset has rows? I'm trying to see if my sql procedure call managed to fill up my dataset.Also, is there an easy way to print the rows to a label?
I have a dataview grid where I am loading data from a sproc. I now need to loop through all of the rows and make changes to some of the cells that are binded through the datasource
I have a piece of code that works for adding multiple rows to a dataset but I think that it is a lot of code and thought maybe someone may know a better way of doing it. I need to add rows to the dataset based on the selection of a combo box. ie if the user selects 15 the the program adds 15 rows to the dataset.
Case cboQty.SelectedItem = 3 Try Dim dr As DataRow
I am new to vb.net and I am trying to query a database and print out the records in the row to the console window. I got it to work, but I have a feeling that there is a more concise way to do this. One thing that I am sure is wrong is that I had to convert the dataset to a datatable to be able to retrieve the values. Is that correct? Could you take a look at the code below (especially the for loop) and let me know what I can improve upon?
I pass it a valid dataset that has the department name and the Department id as a number..20, 40, 30..... I want to get the department number.. I pass it HR(which is in the ds.table) but I am getting an error on the rows.find() "Input string was not in a correct format" it is a string.. what else could i be doing wrong here...
Public Function GetDeptID(ByRef ds As DataSet, ByVal strDepartment As String) As Integer 'Dim dr As DataRow ' Check to see if date is already in the table
I have a form with the datagridweiw object. I have connected it to the datasource and it displays the data fine. I also have set the persissions for editing. I am assuming i need a button for accepting changes to table and a button to cancel. My use for the form is to add or delete rows of data and save the changes. The database and application are both in visual basic and sql server express both 2008.
I have used VB6 for all kinds of database programming. Now I am fairly new to the vb.net. How do we read the records (rows) from a dataset and manipulate data? I want to populate a combobox or a datagrid with a recordset (in VB6 language). What is the .net equivalent of ado dataset, and how do I use it. I have tried several ways using dataadapters and dataset, etc.
I have a strongly typed dataset that has rows with duplicate [sopnumbe] I am looping through them and displaying row data I want to only display the Distinct sopnumbe rows in my initial loop1.. but the sub loop uses the data out of all rows.. So I cant filter the actual dataset.
I have a dataset which is bind to a datagridview. When changes are made and that dataset is modified, i want to edit the dataset and update two datarow with WHO did the change and WHEN did the change occur.
I have a question similar to this one, but reading the (accepted) answer didn't give me much insight, so I'm hoping to state it more clearly and get a clearer response back.
I'm attempting to insert a data row into a table. I'm using TableAdapter's custom "insert nonQuery" that I wrote (it works, I tested) to accept some parameters. I'm fairly new to this business of communication with a database via .NET and what I'm doing is probably wrong by design. My questions are why is it wrong and what's the right way to do it? Both are equally important, IMO.[code]...
I have datagridview1 which contains data and what I want to do is get the data from first selected row then carry out MyRoutine and then do the same for the next selected row until their is no data in: RW.Cells(2).Value.ToString RW.Cells(1).Value.ToString
This is what I have come up with so far: But I can't get it to move on to the next selected row once it does the first. Private Sub Button13_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button13.Click For Each RW As DataGridViewRow In DataGridView1.SelectedRows 'Send the first cell value into textbox2 and other cell value to textbox1' End Sub [Code] .....
Below is my export to csv from listview using vb.net
Function ExportListview2CSV(ByVal lstview As ListView) As Boolean Dim saveFileDialog1 As New SaveFileDialog() Dim csvFileContents As New System.Text.StringBuilder

i want to exclude the records from the 1st and last rows where should i make chages in above code
