Parameter Update Reports 1 Row Updated But No Data In Table Added

Oct 13, 2011

I am getting an incorrect repsonse after an update to a table. In my RowUpdating event I have the following code which builds an Update Parameter to call an SP to update a table. I must be doing something wrong but everything runs fine. My rowsAffected variable reports 1 after the update, but the table never gets the data.[code]I found a solution that is working. On the original DataSource for the update command I needed to add the following.[code]This in essence allows the original data source to call the SP. Note: that the command type needs to stay as TEXT not Stored Procedure as one might think.

VS 2008 - Update A Date Field In Table When A Record Is Updated

Jun 26, 2009

I want to update a date field in my table when a record is updated to reflect when the last update was made. I have this for the parameter: objEXTCommand.Parameters.AddWithValue("@entryDate", Now.Date)

However, this inserts the Date and a time of "12:00:00". I want the date and current system time. I've gone about several ways, but none seem to work. I try this: [Code]

DB/Reporting :: Updating Client Data Tables When Data Table On Shared Drive Is Updated?

Sep 28, 2009

I would like to know the best, or standard, way to accomplish real-time client updates in a small multi-user application using an access data table as a data source.Specifically, this application will be used by 3-4 people. It uses a datatable which is filled on form load and bound to a datagrid at design time. The datatable is stored on a shared drive. The data table on the shared drive is updated in two ways:

1) Users can update the datagrid which then updates the datatable on the shared drive via the data adapter's Update method.

2) A server application does some work on some text files, periodically updating the data table.

I need the clients to reflect the changes to the data table on the shared drive as closely to real-time as possible. I know that the data table stored in memory on the client is disconnected from the data table on the shared drive, so I must query again to get the updates.

1) Is there an alternvative model I can use which is connected, and which will automatically reflect the updates in the data table on the shared drive?

2) If not, what is the best way to check for changes in the data table (so I can know when to call the data adapter fill method)? I am planning to poll the drive for a change to the .mdb file, raise an event and then fill the data adapter when the event is triggered. I am using this method successfully now to check for changes to a text file in another application, and I know how to implement it?

Updated Table Loses Saved Data After Project Rebuild

Mar 17, 2009

since I still use VB6 and the code is in VB8, I can't find the solution.The sub below is executed in a button's click event, and is supposed to save data to his database. It seems to work fine : you can add persons (in a separate form), and see them appear in the datagrid. You can stop the program, go back to the VB editor, and run it again (without rebuild), and the previously added persons will still be visible in the datagrid. But...If you add some persons, then go to the editor and force a rebuild (for example by adding more code), and than run the code again, the the previously added persons are gone (nomore visible in datagrid)!To me, it seems that the problem is to effectively update the database. I have searched on the internet about this topic, and I read that you must "set" the UpdateCommand.

Populating Rdlc Reports From Data In A Form OR Data From An MDF Table

Mar 27, 2008

I have a simple windows form that i would like to send the values of a few textboxes and comboboxes to an rdlc report after saving them (I have VS 2005 standard, so no crystal reports) - it's as follows:

-1 form
-3 textboxes - textbox1, textbox2, textbox3
-1 label - label1
-1 combobox - combobox1
-5 buttons - button1, button2, button3, button4, button 5

the textboxes are labeled length, width, height the combobox is labled unit of measure and contains two options - inches or centimetres the label has text of "your total cubic inches/centimetres is:" - followed by the unit of measure selected.the buttons are labeled save, calculate, print, print preview, and exit.Having said all of the above, the save, calculate and exit button code is easy enough and is good to go - it's print and print preview i'm stuck on the solution i'm after is to take those values and send them to an rdlc report that immediately prints (calls up the default printer dialogue) without preview or anything when the print button is clicked and also have a print preview function as well for when of course the print preview button is clicked.The report has already been created with the titles mentioned above..

ListBox Update As Data Added To Database?

Jan 15, 2012

I have a form where i can enter new product. In that same form i have listbox where i show the current product from the database.

I want to know how to update that listbox as i enter new product into the database so that user can see the current content of the product table.

my code to load the listbox

Try
Dim ds As New DataSet
Dim cmd As New OleDbCommand

[Code].....

To sum it up, what i want is something that will refresh the current display of the listbox so user can see the actual and updated contents of the database.

with the above code, the newly entered product/data can only be seen when the program is closed and reopened again. Which is not very convenient.

Data Table Only Partially Updates (Parameter Related)?

Jan 25, 2012

I have a data table that I am updating. The table has 5 rows.The first row in the data table that has an ID of 1 will not update with new values, but the rest of the data table does update, I can't figure out why.

It is an access database I am updating, Is there a problem with my Update String? Because it updates all of my table except for the first row that has an ID of 1.

Dim sqlSSRTotalUpdateParameters As String = "UPDATE [SSRTotalChecker_" & FullName & "] SET [Totals]=@Totals,[Category]=@Category,[Materials]=@Materials, [Labour - Field Effort]=@LabourFE," & _

VS 02/03 Crystal Reports Parameter Passing?

Aug 12, 2011

I seem to be passing the parameter to the report (I placed the parameter field itself on the report to verify this) but it does grab any information based on this parameter. All of the fields appear with no data but the parameter is showing up correctly.Yes, I have verified that the parameter is in the select statement of the report.The report also is exporting correctly but still without the data.

Changes To Data Row In Table Do Not Update

Oct 18, 2011

I have an application in VB2008 and using SQL Server 2005 Express Edition. I found an error in a value that I had entered in the SQL Table and want to correct it. All I needed to do was to change a numerical value in one of the columns from 18.4 to 16.4. This table is used to fill a combobox drop down menu in the application. After I changed the number in the data row, I saved the change and ran the applocation in debug but the original number still appears in the drop down menu. If I exit Visual Studio and re-open it, the change still appears in the database table but does not appear in the combobox, when I run it in bebug.I have made changes like this many times in this application and this database table, As I recall, all I had to do was save the change and I have never had it fail to update the change in the data row.

Update Data From Data Set And Table Adapter

Oct 6, 2010

I have a windows form program that pulls data from a sql server. That same data is being read from a ASP.NET website that sets properties for the site. The SQL server has 3 tables: tblWebPage, tblObjects, tblProperties. and 6 views for the 6 web page: vWebPage01, vWebPage02, vWebPage03..ect. When the program loads you see buttons for each web page on the site. When the user clicks on the Home Page it loads this data: [code]Now, the problem lies in updating vWebPage02, vWebPage03, ect.. I assume with the same data I can copy my form with the code and change the form name and the data set to build and update. So that's just what I did changed the form name where needed and changed "vWebPage01" to "vWebPage02".When I tested the program My "vWebPage01" form it built and updated no problem. when I went to test "vWebPage02" it built the dataset and table adapter fine but it did not update at all.

Update Existing Folder With New Updated Files?

Jul 6, 2009

im having a problem with replacing some files in a folder, i have made a Auto Upater for a application im making (so beta testers can test it and also get updated stuff to test) now i can replace the Main application.exe with

If File.Exists(Application.StartupPath + "\test.exe") Then
File.Replace(Application.StartupPath + "\update\test.exe", Application.StartupPath + "\test.exe", Application.StartupPath + "\test.exe.old")
End If

This is after i have unziped the main update.zip folder it downloaded

but i also have a Data folder in the Main application folder and inside the new update\Data folder its has updated files now i cant list all files to replace like above as i want be replacing all files all the time, so im looking for something like you have on windows (would you like to replace files) without the prompt its just replaces them, so really im looking for a move and replace without prompting

i have tryed

Directory.Move(Application.StartupPath + "\update\Data", Application.StartupPath + "\Data")

and

Directory.Move(Application.StartupPath + "\update\Data\", Application.StartupPath + "\Data\")

but it errors saying the folder exists and i cant delete the folder as it will have files in that DONT need updating

Db Update - Get All The Data From Table And Set It As The Datasource Of A DataGridView

Jul 28, 2009

I have this

[Code]...

which is supposed to get all the data from my table and set it as the datasource of a DataGridView. You can see where I put in two msgbox's to view how many columns are in the DGV before and after the "update". The first count gives me 22, which is the correct number. After the .DataSource and .DataMember lines are ran, the count jumps to 41 and I have no clue why. All I want to do is clear a dataset, fill it with the new data and set it as the data source of a datagridview. It appears the info is being saved to the table correctly too.
