View 3 RepliesI have some text boxes in my form that takes data and saves the data to the database. There is a combo box on the form that loads data from a specific field of a database.
When I enter and save the new data (using the textboxes), the combobox doesn't show the newly entered data. I tried to refresh the combobox using code like combobox.refresh, me.refresh etc....to refresh the form but nothing is working.
The combobox only display the new data when I close the form and reload the form again. Anyway, the data loading in the combobox is done using datasource, displaymember, valuemember in the properties So, how can I make the combobox show the updated record (field)?
the combobox name is cboManager
the Displaymember: Mname

After several hours of searching the internet I could not find any Report Viewer tutorials that show a project that contains a parent/child report. I'm using rdlc report files.I can create a single report but we want to create a report that shows shows invoice header information followed by the invoice details followed by the next invoice header and details and so on.
If a sample project is not available, do you know of an online tutorial that shows how to do it?I saw something that might help on gotreportviewer.com about subreports, but it's in C# and not VB.Net so I could not figure out how it works.
I have a table there in SQL SERVER 2000 which has five fields[date income amount expense amount]. Now user wants to input first date & last date there in form to show records ok? To show record by one paraemeter was easy for me & I did it by following code. I mean I made one parameter & got one form with one text box & one button & one report viewer. Let me show you my code for button event what I used to show report by one parameter.

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?

I'm having a problem with my crystal report with regards to report footer. I want to display the data from the table, column name "Remarks" in report footer but when I try to call the data it doesn't show the remarks. I'm using VB 6 and mdb files as my back end. Is there any command or fundamental that I've missed?
View 1 RepliesI need advise on how to solve this scenario. I am not sure whether I should use any Report Application such as Crystal Report or I can just simply use datagridview.My scenario:In a new form, a table will show a least 3 columns.
First, ItemID
2nd, Total Quantity Sold for the Current Month
3rd, Total Quantity Sold: Last month
ItemID Current (Nov) October
ABA1 100 85
ABB1 80 90
Hence, I can compare the figure of the current month with the past few month.Right now, I do not have any problems building SQL_String for calculating the Total Qty Sold for the Current month and display it via DataGridView. But I am not sure how to additional column that calculate the Total for the past few month
I am trying to convert a VB6 Data Report (.dsr file) to a Crystal Report through the migration process within Visual Studio. I have read articles that reference adding a Data Report to a Project from Visual Studio 2005/2008 and that it will convert the Data Report to a Crystal Report, but I have not been successful in doing so. Does the VB6 Data Environment need to be converted too? Has anyone been able to do this successfully and if so, how?

View 8 RepliesWhat I have managed to do is currently display a chart with 3 bars on it linked to textboxes what have numerical values in them when the form is loaded. i.e TextBox1 has an initial value set in it's properties of 10, TextBox2 has a value of 20, TextBox3 has a value of 30.
When I run the program the graph displays these values correctly.
I have also got a button, Button1 which when pressed will plot the chart again, (so if I manually change the values in the TextBoxes after the form has loaded), it will display the new values via the bars.
The problem I have is that if if once the initial values have been plotted when the form loads, i.e. 10, 20 & 30, the Y axis of the chart has a maximum value of 35, so that all the initial values for the bars are shown. But if I change the values to say 15, 30, 80. and then press Button1 to update that bars to thier new values, the bars change but the one that show's 80 can not been seen fully as it goes off the chart, as the Y axis still only shows a maximum value of 35!
Does anyone know how to get the chart to resize to be able to display all the bar values within the chart each time the values are changed and the Button1 is pressed, whether it be reducing the graph for smaller values or enlarging the chart for higher values?
I am not 100% sure I am going about it in the correct way as I have not got any experience in using charts and am having to stuble about the net trying to find basic example code of how to setup and use a chart
My code so far is:
Imports System.Windows.Forms.DataVisualization.Charting

I have an issue with a data table that I have updated using the datatable.update command.The datatable is bound to the datagridview using dgv.datasource = datatable.I have used INSERT and UPDATE commands and the INSERT command writes the data back to the database ok. However my problem is that it the dgv is not updated with the primary key (ID field) from the database. So when I save a second time, instead of updating it just inserts the data again.

I have a DataTable that's constantly being updated with new data from my database via a timer. That data is eventually reformatted and displayed in a DataGridView control.In an effort to prevent the DataGridView from completely refreshing from re-databinding (thus, clearing out selections, resetting scrollbars, defaulting sorting settings, and making the gridview flash as it reupdates), I'm simply removing old rows from the datagrid that no longer exist in the DataTable, and adding new rows to the datagrid that appear in the DataTable since the last update.
For the sake of simplicity, we'll call DataGridView the LEFT table, and DataTable the RIGHT table I'm looking for a way to go through both tables (LEFT and RIGHT), and remove old rows that are no longer in RIGHT and delete them from LEFT. And look for new items in RIGHT and add them to LEFT. Each table has a column called "RecID" containing a unique id for each entry that can be used for comparison. is there a way to do this all in one loop? What I'm looking for, in pseudo code:
<loop through everything>
if RecID does not exist in LEFT but exists in RIGHT
add new item to LEFT
if RecID does exist in LEFT but does not exist in RIGHT

I have an Access database that is updated directly in Access. I'm trying to write a program to 'monitor' the database, and have a DataGridView control showing the contents. When the program is first started, it shows the current data in the DB fine, however, I've been unable to get it to refresh with any updated data from the mdb file. I have a timer running on 5 second intervals, and if i clear the dataset, the DataGridView refreshes to empty.

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.
View 3 RepliesI want to work on a project I have in mind and this envolves saving data which would need to be updated every time the user exits the program. I suppose I need to know how to save a file to a blank text document, and how to get the application to read the information when it is called for. I believe I need to set delimiters or such, the helpfile is useful, but limited and some information is not listed at all.
View 7 Repliessince 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.
