Hallo All,
I am having issues with Viewing report that I added to my project and I need your help please.
I am using Access DB, VB 2010, .NET4.5 and As you can tell I am in learning process, so I am new to VB.
Any help given is highly appreciated.
HERE are the Two error I am getting:
1 st one. I want to view Total Profits for all times.
Error "A data source instance has not been supplied for the date source 'AllTimeReportDataset'
I named this on the wizard when I was creating the report wizard but how do I add the data source.
2nd Error: Happens when I want to view Total profits between two Date:
HERE is the Error: The Report definition for the report 'TBS.TotalProfitsBetweenTwoDates.rdlc' has not been specified.
Here is my code:
Private Sub ShowReportBtn_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ShowReportBtn.Click
If ReportComboBox.Text = "Total Profits for all Times" Then
'Fill the information for the report Selected.
Dim TA As New TBSDSTableAdapters.TotalProfitForALLTimeTableAdapter
Dim SelectedDS As New TBSDS
TA.Fill(SelectedDS.TotalProfitForALLTime)
'Clear previous report run (Data Source) and Display the new report selected
ReportViewer.LocalReport.DataSources.Clear()
'Create a new Data Source now ---selected report from Combo box ---In this case Total report for all time
'Dim RDS As New Microsoft.Reporting.WinForms.ReportDataSource("TBS_TotalProfitForAllTime", SelectedDS.TotalProfitForALLTime)
Dim rds As Microsoft.Reporting.WinForms.ReportDataSource = New Microsoft.Reporting.WinForms.ReportDataSource
rds.Name = "TBSDS_TotalProfitForAllTime"
rds.Value = SelectedDS.TotalProfitForALLTime
'tell the report control to use the data source
'also use the report template created (rds)
ReportViewer.LocalReport.DataSources.Add(rds)
ReportViewer.LocalReport.ReportEmbeddedResource = "TBS.TotalProfitForAllTime.rdlc"
ReportViewer.RefreshReport()
ElseIf ReportComboBox.Text = "Total Profits between two Date" Then
Dim TA As New TBS_RestDSTableAdapters.TotalProfitForALLTimeTableAdapter
Dim SelectedDS As New TBSDS
TA.FillByFilteringBetweenTwoDates(SelectedDS.TotalProfitForALLTime, DateTimePicker1.Value, DateTimePicker2.Value)
'Clear previous report run (Data Source) and Display the new report selected
ReportViewer.LocalReport.DataSources.Clear()
'Create a new Data Source now ---selected report from Combo box ---In this case Total report for all time
''''Dim RDS As New Microsoft.Reporting.WinForms.ReportDataSource("TBS_TotalProfitForAllTime", SelectedDS.TotalProfitForALLTime)
Dim rds As Microsoft.Reporting.WinForms.ReportDataSource = New Microsoft.Reporting.WinForms.ReportDataSource
rds.Name = "TBS_TotalProfitForAllTime"
rds.Value = SelectedDS.TotalProfitForALLTime
'tell the report control to use the data source
'also use the report template created (rds)
ReportViewer.LocalReport.DataSources.Add(rds)
ReportViewer.LocalReport.ReportEmbeddedResource = "TBS.TotalProfitsBetweenTwoDates.rdlc"
ReportViewer.RefreshReport()
End If
End Sub

can i develop a software that splits ,joins,compress and decompress using visual basic 8.0?

Yes, if you have some programming skills. Google or MSDN will help you to find the documentation for each feature.
|
|
|
|
|
Since we know absolutely nothing ablut you and your skill set, it's impossible to answer this question.
Can any one of us do it?? Sure!
Can you?? We have no idea.

insert multiple values in single column from diff text boxes in dtabase using vb.net
|
|
|
|
|
Is there a question, or are you asking for permission?
|
|
|
|
|
You can concatenate all the values in the textboxes and insert them into a column. Or delimit them with a character and insert them.
Either way you can only have one piece of information inside a column.

|
|
|

try this:
Private Sub insertData()
Try
Dim con As SqlConnection = Nothing
Dim cmd As SqlCommand = Nothing
con = New SqlConnection(System.Configuration.ConfigurationManager.ConnectionStrings("inline").ConnectionString)
con.Open()
cmd = New SqlCommand("insert into table_name(column_Name) values ('" + TextBox1.Text + "," + TextBox2.Text + "')", con)
cmd.ExecuteNonQuery()
con.Close()
lblMsg.Text = "Saved Successfully"
Catch ex As Exception
lblMsg.Text = ex.Message
End Try
End Sub

Please get yoursel a good book on the subject; posting questions here is not the way to learn programming. For a start you could read .NET Book Zero[^], and then work through these tutorials[^].
|
|
|
|
|
Please post C# questions in the C# forum[^].

Hello..........
I am beginner in c# programming, want to know How does this code executes. Kindly describe in detail.
!System.Text.RegularExpressions.Regex.IsMatch(e.KeyChar.ToString(), "\\d+")
Soon reply will be appreciated.....!!!!
Thanks....

Calls the method "IsMatch" on the Regex class (from the "System.Text.RegularExpressions" namespace), with the arguments of the current keycharacter (provided by an event you did not copy/paste) and a RegEx. Then it inverses the outcome.
Not very helpful, is it? It compares a key with a RegEx and reports whether they match. You'd have to look up the "\\d+" part on this page[^] from MSDN, I don't know the regex-code from my head.

It tests whether the e.KeyChar property (which is presumably a char) is not (note the ! at the start) a decimal digit.
It's a significantly less efficient version of:
!(e.KeyChar >= '0' && e.KeyChar <= '9')
or:
(e.KeyChar < '0' || e.KeyChar > '9')

Did you notice that this is the Visual Basic forum? Also a Google search for "masked text box" should find you some useful reading material.

my youtube video downloader app was working but it stopped working due to Dec-2012 YouTube changes. my code is unable to load the download format.
Currently, the video info loads but the application is unable to load the available download formats and download the video.
Download the VB6 Source here http://www.abhisoft.com/misc/UTubeVB6.zip
I hope anyone is able to take a look at the code and see what's wrong?
I think the error is in here:
DownloadRequest.Open "GET", m_StrVideoURL, True
|

You're not going to get help with this. Downloading video from YouTube violates their terms of service and we're not in the habbit of breaking those.

Hi all,
It's my first question in this forum...just read a response to another guy that helped me a lot.
I am working for some project in my university and they asked me to make an application in vb.net. Then I had to save different data for every user in order to check his own work, so I used SQL management studio to import some information to arrays there.
The big problem that I face now, it that they would like to work this project online, so as users can open it through their website. I have no idea if all the code I wrote in vb.net and connections between VISUAL studio and SQL studio could be transfered online ! Maybe I could convert most of them so as to run the project online.
Can anyone help me ????
I would really appreciate every advice or help !!! I am searching for a solution so as not to lose my project( that I almost finshed ).
Thans in advance !!!

Without knowing what your project does, it is hard to determine how to go about this..
Basically, you would need to develop a web page which collects the data and stores it in the database your already have configured.
It can be done. More details are needed. (Desccribe what data is collected and stored)
Good luck.

We have many VB2008/2010 programs converted from VB6.
They used the VB6 Control Arrays (which I really miss).
The VB.Net code uses VB6 compabitity control arrays which works well but hard to maintain if new control arrays are needs.
We have begun replacing these with List (of ..) and AddHander's which also works well.
What we would like is for our code to populate the list ofs and do the AddHandlers to be done when the InitializeComponent is done.
So how can we 'extend' the IntializeComponents to our code or have our code run after the InitializeComponents.
Thanks
