SQL Query Works In SQL Server But Not When Called From Checkbox

Nov 21, 2010

I've got a datagrid with checkboxes which calls a routine called checkbox_CheckedChanged. So far, so good. I've managed to get it to work out the value of another column in the dataview, which allows me to ascertain the id of the row I'm dealing with. I'm trying to get it to change the value of the column which defines the initial value of the checkboxes, but the SQL I've written doesn't work when called by vb.net - it does work when entered manually into SQL server, however. Here's my code behind:

Parameterized Query : Works With Execute Query But Not In Code?

Oct 22, 2009

I have created a parameterized query in my tableadapter. Here is the SQL:

SELECT CalcinerID, Comments, CorrectiveActions, CrucibleOxideWt, CrucibleWeight, DCPressure, DCTemperature,
Date, DischargePressure, FeedPressure, FiredCrucibleOxideWt, GmSampleWt, LIMSNumber, LotNumber, MaterialType,
OperatorID, QualLabOperator, QualLabTimeStamp, RecordID, ToteBinNumber [code]....

When I use the Execute Query button in the Tableadapter Query Builder, the query works fine; I get all the rows I expect. However, when I run this in my code, the query behaves like an equality statement (i.e. Lotnumber = @Lotnumber) rather than a LIKE statement (Lotnumber LIKE '%' + @Lotnumber + '%').Here is the code that is not behaving correctly. Note that I have a textbox, LotSearchTextbox, where I enter the portion of the Lotnumber that I want to use as the filter. I also have a button, LotSearchButton:

Private Sub LotSearchButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LotSearchButton.Click
Try
Dim SomeNumber As Integer = Me.LotCalcinerO2TableAdapter.FillByLotNumber(Me.CalcinerDBDataSet.LotCalcinerO2,[code].....

why the query works in the Query Builder but not in the code?

VS 2010 Checkbox - Field In My Table Called RentPaid

Jun 16, 2012

I have a field in my table called RentPaid, its set to bit data type. On my form I have a button called Pay Rent, when the user clicks that button I want my checkbox set to true.

I've tried both of these:

Me.chkRentPaid.Text = True

Me.chkRentPaid.Checked = True

Neither seem to be written to my SQLExpress database, however EVERY other field on my form does. The field shows up in my datasource for that form, I just dragged it over to my form with the rest of my fields.

Oracle Query Works In SQL+ But Returns No Rows

Oct 24, 2011

I am using the OLEDB adapter (Oracle OLEDB) with Oracle 10.2.0.3.0. My code generates the SQL for the query, then when I execute it into an OLEDBDataReader, the HasRows is False. However, if I output the contents of the query string, copy, and paste into SQL+ (logged in as the same user from the same client machine), it returns 993 rows. What gives??

VS 2008 : SQL Query - Works At Design Time But Not Runtime?

Aug 16, 2010

I've created an SQL Query using the query builder. In the query builder, you can test the query by clicking the button "Execute Query", and entering the desired values in the parameter fields.

My query returns the correct results when I do this, but when I seemingly pass the same values at runtime, I get 0 records returned.The query is designed such that you can pass nulls if you don't wish to filter data by that particular parameter.
SQL Query:


SELECT ID, UPC, Quantity, Manufacturer, Style, Color, Size, Category, DateReceived, Cost, OriginalRetail, Retail, LocationID
FROM Inventory
WHERE (UPC = @UPC OR

[code]....

In the query builder "Execute Query" dialog, I enter a value I know that the db contains in the "Size" field, "1/1/1900" & "1/1/2199" in Dates A & B, respectively, and nulls for all other fields. This returns 1 record, which is just as I expected. It works correctly.But when I pass the same values into the method created by the designer, I get 0 records returned. I can't figure out where the problem lies. Even if I enter nulls for all fields other than the dates, it returns 0. This tells me that the dates are causing the problem, but I can't figure out why, because I'm passing strings equivalent to what I entered in the query builder.

VS 2008 SQL Constraint Exception - Works Fine In Query Builder

May 3, 2011

I have created a query method for my tableAdapter in the dataset designer. I typed the command text manually, but tested it in the query builder after I got a Constraint Exception when debugging. When running in the query builder via 'Execute Query' I get exactly the results I expect. When running the application I get this exception: "Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints." I tried temporarily setting my dataset's EnforceConstraints property to FALSE but still get the same exception. I can't understand why the Query Builder would return the correct datatable but running the app would not. Is this a bug?

Email Code Works On Local System But Not From Web Server?

May 2, 2011

I have developed an ASP.Net 2.0 application and I am facing problem in sending email from my Web Server. Following is the VB code I have used to send email from my web application. Thing is when I try to send email from my local system (laptop) the email goes out fine and reaches the recipient address instantly but when I try to send email from my web server it fails.My hosting provider gave me a relay-host address for sending out email. The email goes out fine but the relay host has an annoying amount of delay in email delivery which is a problem during the sign up process.

Here is the code I am using:I have imported system.net.mail in my code and used async="true" on the aspx page.

Private Sub SendMail(ByVal actcd As String)
Dim mailMessage As New System.Net.Mail.MailMessage
mailMessage.From = New MailAddress(support@ihomejobs.com)

[code]....

I have tried the above settings and they work fine from outlook and the application when tried on my laptop but these settings fail on web server.I want to send email from my web server without using a relay-host.

.net - LINQ Query For Filter By Selected Items In Checkbox List?

Jun 30, 2011

Could not find this through Google or in SO questions.I have a checkbox listbox on my form. I want to filter my List by the list of selected Ids from that listbox that are checked, in SQL I would have done this like "Where TypeId In (1, 4, 5, 7)"... how do I do that in LINQ?

I feel like I am missing a really obvious answer, but cannot get it.

For argument sake... here is the what I have for sample data:

In Colors (List<of currentColors>)
ID, Name, TypeId
1, Red, 1
2, Blue, 1
3, Green, 2
4, Pink, 3

Selected Types 2 and 3 in CheckboxList: filteredColors

.net - Out Of Process COM Server Works Fine In The Unit Test Harness But Not In The Real Service?

Jun 1, 2011

We have a WCF service hosted in IIS that currently calls a VB6 DLL to do part of its job. This works fine, but we can't deploy the service to a 64-bit target environment without configuring IIS to run it in a 32-bit worker process.I am currently investigating ways around that restriction. Porting the VB6 DLL to .NET is not possible for various reasons, so I created an ActiveX EXE wrapper around the DLL in VB6, so that the service can run in 64-bit and the VB6 parts in 32-bit.

When I tested the service I got this error:

Type: System.UnauthorizedAccessException
Message: Retrieving the COM class factory for component with CLSID {9AE7303B-D159-43F6-B1A5-52D297581820} failed due to the following error: 80070005.

After some Googling I found that this is due to either:

Calling an MS Office component
DCOM permissions not being configured
NTFS file permissions not allowing read/exec access to the IIS worker process identity (ASPNET in my environment)

Of these:

Definitely not applicable Also not applicable; I am not hosting the EXE in DCOM or COM+, just a simple COM out-of-process activation
This looks likely; however, I checked the permissions, and NTFS reports that the Users group (which ASPNET is a member of) does indeed have read/exec access to the file I tried calling the EXE from a unit test fixture, which is executed in my admin-level account rather than the IIS worker process account, and it worked fine, so the error is definitely something to do with permissions. I'm not sure what to do next.

UPDATE:The IIS virtual directory is configured for Anonymous+Windows access; the WCF service uses only Anonymous authentication, the Windows authentication is for the VS debugger. Task Manager reports that the aspnet_wp.exe process is definitely running in the ASPNET account.I explicitly granted Read and Execute access to the ASPNET and IUSR_<machine> accounts on all the COM exes and dlls involved. This made no difference.

I explicitly granted Local Launch and Local Activation access to the ASPNET and IUSR_<machine> accounts on the relevant interfaces in the DCOM configuration. This made no difference either.Keep trying to get this working somehow.Go the whole hog and host the EXE in COM+.Give up. Tell users that the WCF service must be configured to run in a 32-bit app pool on 64-bit Windows.

Have A Column In The Datatable Called Amount And A Textbox Acting As The Filter Called Say Maxamount To Set It?

Feb 9, 2011

i was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails.

Properties - Default Property Set Being Called Mysteriously Called?

Apr 2, 2012

I have the following line of code in my program:

JCL_History.Enqueue(JCL_History(I))


This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:

Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))

[Code].....

In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.

After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.

So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.

Grid View Checkbox And Javascript Not Informing Server Side Code

May 6, 2011

I've got a asp.net gridview and inside of the grid view I have a check box at the header of the grid view like so: [Code] This gives me a nice little check box at the top of the grid view, the event OnCheckedChanged calls a function called SelectAllRows that looks like this: [Code] So if I click this header checkbox it checks all of the items in the gridview, and if I uncheck it, it unchecks all the items in the gridview. This works fine...but what doesn't seem to work is if the page loads up and I check the grid view header checkbox to true and it selects all the items in the gridview, then i click a button such as a DELETE button that calls some server side code. That code simply loops through the grid view and checks if the checkbox has been checked, if it is it calls code to delete an item.
