Check the joins of your query providing the data to your sub reports. Chances are you have linked 2 or more tables together, but one of them has no related data. If this is the case, then change the link to Always show data from the main table.

Please your explanation is unclear to me.
The query for the main report is
SELECT ComplusoryFields.CFactor, ComplusoryFields.MudWeight, ComplusoryFields.CirculationRate, ComplusoryFields.CurrencyForMudCost, ComplusoryFields.WellName, ComplusoryFields.ReportType, ComplusoryFields.DataDate, DataIdentity.DataID, ActivitityRemarks.Remark, DrillingMudProperty.Alkanity, DrillingMudProperty.API, DrillingMudProperty.Chlorides, DrillingMudProperty.FlowLineTemperature, DrillingMudProperty.Gel0Mins, DrillingMudProperty.Gel10Mins, DrillingMudProperty.HTHPFilterates, DrillingMudProperty.MBT, DrillingMudProperty.YP, DrillingMudProperty.PV, DrillingMudProperty.MudWeightIn, DrillingMudProperty.MudWeightOut, DrillingMudProperty.Water, DrillingMudProperty.Solids, DrillingMudProperty.Oil, DrillingMudProperty.AveROP, DrillingMudProperty.MaxROP, DrillingMudProperty.VIS, DrillingMudProperty.ShaleDensity, DrillingMudProperty.ShaleFactor, DrillingMudProperty.FlowLineTemperatureScale, DrillingMudProperty.pH, MudWeightChanges.Depth, MudWeightChanges.OldMW, MudWeightChanges.NewMW, PressureLosses.DxC, PressureLosses.EMWLOT, PressureLosses.EstOverBalance, PressureLosses.EstFratureLoss, PressureLosses.EstPorePressureLoss, PressureLosses.MWDPressureLoss, PressureLosses.PipeRunSpeed, PressureLosses.CasingShoePressureLoss, PressureLosses.DxTrend, PressureLosses.EMWLOT2, PressureLosses.EstFratureLoss2, PressureLosses.EstPorePressureLoss2, PressureLosses.HydrostaticsPressure, PressureLosses.HydrostaticsPressure2, ReduceCirculatingRates.Pressure, ReduceCirculatingRates.SPM, ReduceCirculatingRates.Pump, Reports.ADT1, Reports.ADT2, Reports.Operator, Reports.Contractor, Reports.TVDDepth, Reports.MDDepth, Reports.Rig, Reports.Operation, Reports.ImagePath, Reports.SpudDate, ComplusoryFields.MudCost_Notes, ComplusoryFields.MudCost_Coins
FROM Reports RIGHT JOIN ((PressureLosses RIGHT JOIN (MudWeightChanges RIGHT JOIN (DrillingMudProperty RIGHT JOIN (ActivitityRemarks RIGHT JOIN (ComplusoryFields RIGHT JOIN DataIdentity ON ComplusoryFields.DataID = DataIdentity.DataID) ON ActivitityRemarks.DataId = ComplusoryFields.DataID) ON DrillingMudProperty.DataID = DataIdentity.DataID) ON MudWeightChanges.DataID = DataIdentity.DataID) ON PressureLosses.DataID = DataIdentity.DataID) LEFT JOIN ReduceCirculatingRates ON DataIdentity.DataID = ReduceCirculatingRates.dataId) ON Reports.DataID = DataIdentity.DataID;
The query for the subrepotA is
SELECT DataIdentity.DataID, DrillingPumps.PumpNumber, DrillingPumps.RodDiameter, DrillingPumps.StrokeLength, DrillingPumps.Efficency, DrillingPumps.PumpOutPut, DrillingPumps.PumpSize, DrillingPumps.LinearDiameter, DrillingPumps.PumpType, DrillingPumps.PumpStatus, ComplusoryFields_1.DataDate, ComplusoryFields_1.ReportType, ComplusoryFields_1.CurrencyForMudCost, ComplusoryFields_1.CirculationRate, ComplusoryFields_1.MudWeight, ComplusoryFields_1.CFactor
FROM DataIdentity LEFT JOIN (DrillingPumps RIGHT JOIN ComplusoryFields AS ComplusoryFields_1 ON DrillingPumps.DataID = ComplusoryFields_1.DataID) ON DataIdentity.DataID = ComplusoryFields_1.DataID;
And The query for the subrepotB is
SELECT BottomHoleAssembly.HoleOrCasingType, BottomHoleAssembly.HoleInnerDiameter, BottomHoleAssembly.PipeOrCollarType, BottomHoleAssembly.PipeInnerDiameter, BottomHoleAssembly.PipeOuterDiameter, BottomHoleAssembly.PipeAndCasingLength, ComplusoryFields.CFactor, ComplusoryFields.MudWeight, ComplusoryFields.CirculationRate, ComplusoryFields.CurrencyForMudCost, ComplusoryFields.WellName, ComplusoryFields.ReportType, DataIdentity.DataID
FROM (BottomHoleAssembly RIGHT JOIN ComplusoryFields ON BottomHoleAssembly.DataID = ComplusoryFields.DataID) RIGHT JOIN DataIdentity ON ComplusoryFields.DataID = DataIdentity.DataID;
All tables are joined by a DataID .The DataIdentity table suppies the DataID to use

I have been looking into creating a calculator that requires the user to type in what they want solved. Not order, no clicking buttons, and no parentheses. They type everything in, click a button, and poof. They get their answer. Obviously, this needs to follow the order of operations (PEMDOS). For the time being, i am not doing square roots or powers. I would like the user to be able to type in the stuff they want solved in infix notation, while it should be solved using RPN. I have problems coming up with code to convert it- probably because i dont entirely understand the conversion. Here is a link to what i found, which pretty much spells it out.
http://en.wikipedia.org/wiki/Shunting_yard_algorithm[^]
If anyone could help me with the code to convert infix notation to RPN, i would be very thankful. As of right now, this is what i have.
<br />
equation = txtequation.text<br />
length = len(equation)<br />
for i = 1 to length<br />
temp = mid(equation,i,1)<br />
tempstack.add temp<br />
output = output & temp<br />
next i<br />
but of course, that doesnt move stuff around.

I created a new class and inherited the windows combobox. I also created a TextChanged event for the combobox. Then compiled it into a dll. When I use the combobox in a windows project the TextChanged event does not fire. What do I need to do to get it to work?
|
|
|
|
|
Can you post your TextChanged event code? It might have to do with the way you are handling it (overloads, shadows, etc.)

Public Class Class1
Inherits System.Windows.Forms.ComboBox
Public WithEvents ComboBoxMain As New System.Windows.Forms.ComboBox
Public Sub ComboBoxMain_GotFocus(ByVal sender As Object, ByVal e As System.EventArgs)
End Sub
End Class
When the class is used in a windows project the gotfocus event never fires. What do I need to do to get this to work? Thanks.

Here's what appears to have happened:
You inherited a combo box - this is good. However, now your entire control is the combo box; you don't need to create another. You have also declared a combo box variable, but there is no need to do this and it will never fire because you haven't added the combo box to the Controls collection and therefor it isn't visible in the UI.
Try this:
1. Take out the Public Sub and Public WithEvents statements (and the End Sub, of course).
2. In the object drop down in the upper-left corner of the code window, select (Class 1 Events).
3. In the event drop down list in the upper-right corner, select GotFocus.
You will now have a GotFocus event that will fire appropriately.

|
|
|
|
That worked perfectly.
Thanks a lot!

You're welcome.

One other question about this. My combobox class has a gotfocus event. I drop that combobox class onto a form and create a gotfocus event in that form. Which gotfocus event runs first, the one back in the defining combobox class or the one in the form?
|
|
|
|
|
The one you defined in your class will fire before the event on the form.

the below is an example of what you want.
<ProgId("DLLNAME.CLASSNAME"), Guid("C4CAB66D-291F-4bd7-9D5C-2E417AB75F49"), ComVisible(True), ClassInterface(ClassInterfaceType.AutoDispatch)> _

Sir,
Can i programically find whether the sql server is installed or not in vb.net 1.1
Thanks
|
|
|

|
Sir,
Please explain the difference between byval and byref.
Thanks

ByVal passes an argument to a method, well, by Value. It passes the actual value of the argument to the method you're calling by pushing that value on the call stack. When the method gets control, it pops the values off the stack and uses them.
ByRef passes an argument by pointer. Instead of passing the value, it passes an address to the value stored in memory somewhere. The addess is pushed onto the stack and passed to the method, which pops that address off the call stack, and now knows where in memory to find the value.
You can find out more here[^].

Simple class instantiation and method calls. There's no magic going on between layers.

Hi,
I have a stored procedure and it is returning a table as a result.
How can i call d proc & Capture table from Vb.Net using Connected arch
Thanks...

Hi
You can retieve data using a stored procedure in the same way as any other query. There is other (more optimal) ways to retrieve data using a SP, but this is the simplest.
Example:
'---Create Connection
Dim ConnectionString As New SqlClient.SqlConnectionStringBuilder
ConnectionString.DataSource = "localhost" 'ServerName
ConnectionString.InitialCatalog = "MyDataBase" 'DatabaseName
ConnectionString.IntegratedSecurity = True
'Open Connction
Dim Connection As New SqlClient.SqlConnection(ConnectionString.ConnectionString)
Connection.Open()
'---Create/Open Reader
Dim Reader As SqlClient.SqlDataReader
Dim Command As System.Data.SqlClient.SqlCommand = New System.Data.SqlClient.SqlCommand("MyStoredProcedureName", Connection)
Command.CommandType = CommandType.StoredProcedure 'Optional
Reader = Command.ExecuteReader
While Reader.Read
MsgBox("Field 0 :" & Reader.Item(0).ToString)
MsgBox("Field 1 :" & Reader.Item(1).ToString)
End While
'Close Reader
Reader.Close()
'Close Connection
Connection.Close()

Thanks
but genarally we r use Exectenonquery() for stred proc
is tere any othre way by using nonquery
Thanks

ExecuteNonQuery only returns Rows Affected, and populates any Output paramters that was mapped. So this would not work well if you need a resultset.
You could use ExecuteReader/Command, or Use a DataAdapter to retrieve the data.
