I'm quite new to .NET and very new to TableAdapters. I am currently working on updating an existing program and am required to alter some SQL code to update a field in one of the databases where I work. I've changed my VB and code and everything in terms of my UI is good to go so I am now trying to update the TableAdapter that is used to account for my change.
I am adding a parameter (#jobNumber) and wish to update the field 'DISCRETE_JOB' in the database table I'm working in.
I've added in the 'DISCRETE_JOB' parameter to my INSERT INTO statement as the third parameter and added the '#jobNumber' as the third parameter in the VALUES() line of my SQL.
After Finishing the changes are there when I bring up the tool-tip (by hovering mouse over the TableAdapter Query) but the actual parameters listed beside the name of the Query int the DataSet.xsd file are not updated
Looks like-> InsertData(#Param1,#Param2,#Param3)
Should look like -> InsertData(#Param1, #Param2, #jobNumber, #Param3)
Even after saving changes to the .xsd file the parameters don't SHOW the changes of parameters. I also took a look at the DataSet.Designer.vb file for the DataSet.xsd file and it doesn't appear that my new parameter has been taken into account.
Again, I am new and there may be a couple of things I'm supposed to do to make these changes happen, but I just don't want to mess anything up, as there's a lot of queries in the file for this program.
Thanks! Let me know if I need to provide more detail.
UPDATE: I fixed my problem, though I'm still not sure exactly what was going on and why the parameters weren't updated automatically.
Here's the fix:
The SQL code I added remained in place, but I needed to manually add the parameter I wanted. To do this I went to the properties of the query in question and clicked 'Add', filling in the correct fields based on what the existing parameters looked like as a guide line.
Hopefully this can help someone else too!

I am rather new to coding an Access Application and I have a rather strange error I do not seem to be able to resolve.
I have multiple Forms which are used to write data to some tables. Basically one Form per table.
Mostly the forms are just used to show a selection of the data in the tables. To make sure that noone accidentally alters some data you have to press the button "alter" first, which unlocks the fields to alter the dataset. In one form, however, when you ppress the alter button it switches the dataset. I have one column which is an automated ID which serves as a primary key to distinguish the data from one another.
So when I am debugging the issue and print this ID (Debug.Print Forms(formName).Controls("ID")) it returns the ID of the data that I want to alter, but as soon as I access the data and change one field (Forms(formName).Controls("Column1") = "foo") and print the ID again the ID switched to a completely different dataset.
I have absolutely no clue how that could happen. There is no other code being processed in between. I have googled for multiple hours but have not found anything in this regard yet. Maybe I am just using not the right keywords.
Any help is highly appreciated.
Thanks in advance :)
I have the following issue.
In the past, we have added some fields to transaction IH09.
However last year we migrated to HANA and a lot of programs were updated in the process including the program RIMARA20, which is the program behind IH09.
IH09 has worked fine with the added fields were seen.
Last week I was asked to add another field and I did it however although the field catalog has the new field, it is not shown in the output of IH09.
I have debugged the code countless times trying to figure out what is going on but I don't know what happens.
This program internally uses the function REUSE_ALV_GRID_DISPLAY.
We still have the former SAP environment and I tried to make exactly the same enhancement with this new field and I can see it as expected.
In other words; the same field, the same data element, and the same enhancement in both environments but in the HANA instance I cannot see it.
I'm truly frustrated because I see the new field in the field catalog but I can't make it visible in the report.
Any advice on this issue?
Sounds like the REUSE_ALV_GRID_DISPLAY has "remembered" the old catalog
Did you try
to reset the layout / add the missing field?
I have a data set with multiple tables. In one of these tables I have included some scalar queries that take various fields of the table and spit out a single result (for instance average of fields X, Y, and Z), etc. Up to now, I have had great success with this, but now I am getting a very odd issue cropping up.
When I try to add a new scalar query, I am putting my SQL in the screen and naming my query, just like I normally do. However, whenever I do this now, it creates a duplicate of the DataSet.Designer file (now DataSet*1*.Designer), and I start to get compiler errors since all functions within the partial classes are duplicated. I am only able to back out of this by deleting the new designer file, in which case my new SQL query is now unavailable (but I still see it in the original designer view).
I am not sure why this is happening. Can anyone shed any light on why the IDE is creating a new DataSet.Designer file instead of modifying the original?
Discovered the answer. It looks like this may happen if some process is using the original designer file, and the IDE tries to generate a new one. Unfortunately, it doesn't reconcile that the old one is still there. This will correct the issue.
Delete the newest (offending) designer file from your project
Close the project.
Open the vbproj file using a text editor.
Search for the following..
<LastGenOutput>myDataSet1.Designer.cs<LastGenOutput>
Take the 1 off of the dataset name
save the file and reopen your project.
I'm trying to load data from my database into an excel file of a standard template. The package is ready and it's running, throwing a couple of validation warnings stating that truncation may occur because my template has fields of a slightly smaller size than the DB columns i've matched them to.
However, no data is getting populated to my excel sheet.
No errors are reported, and when I click preview for my OLE DB source, it's showing me rows of results. None of these are getting populated into my excel sheet though.
You should first make sure that you have data coming through the pipeline. In the arrow connecting your Source task to Destination task (I'm assuming you don't have any steps between), double click and you'll open the Data Flow Path Editor. Click on Data Viewer, then Add and click OK. That will allow you to see what is moving through the pipeline.
Something to consider with Excel is that is prefers Unicode data types to Non-Unicode. Chances are you have a database collation that is Non-Unicode, so you might have to convert the values in a Data Conversion task.
ALSO, you may need to force the package to execute in 32bit runtime. The VS application develops in a 32bit environment, so the drivers you have visibility to are 32bit. If there is no 64bit equivalent, it will break when you try and run the package. Right click on your project and click Properties and under the Debug menu you'll need to change the setting Run64BitRuntime to FALSE.
you dont provide much informatiom. Add a Data View between your source and your excel destination to see if data is passing through. Do do it, just double click the data flow path, select data view and then add a grid.
Run your app. If you see data, provide more details so we can help you
Couple of questions that may lead to an answer:
Have you checked that data is actually passed through the SSIS package at run time?
Have you double checked your mapping?
Try converting within the package so you don't have the truncation issue
If you add some more details about what you're running, I may be able do give a better answer.
EDIT: Considering what you wrote in your comment, I'd defiantly try the third option. Let us know if this doesn't solve the problem.
Just as an assist for anyone else running into this - I had a similar issue and beat my head against the wall for a long time before I found out what was going on. My export WAS writing data to the file, but because I was using a template file as the destination, and that template file had previous data that had been deleted, the process was appending the data BELOW the previously used rows. So, I was writing out three lines of data, for example, but the data did not start until row 344!!!
The solution was to select the entire spreadsheet in my template file, and delete every bit of it so that I had a completely clean sheet to begin with. I then added my header lines to the clean sheet and saved it. Then I ran the data flow task and...ta-daa!!! Perfect export!
Hopefully this will help some poor soul who runs into this same issue in the future!
I'm building a Sharepoint 2010 export tool for back up reasons (a bit like the filemanager from Metavis).
When downloading a file to local disk I need to back up the metadata associated with the document. Which I will store in a csv-file. My first approach was to iterate all listItem.fieldvalues, but that doesn't really work because some fieldvalues are complex types, which would needlessly complicate the backup file. Some values even have line endings, for example "MetaInfo". Furthermore not all values are needed to restore the content when that might be necessary.
So my idea is to only get the values from the Fieldvalues collection which are needed to do a functional restore, supplemented with all the user added metadata.
To do this I want to check all fieldvalues against an exclusion list to see if it is present. If it is present don't back up. If it is it is either user generated metadata or a value I need like for instance "author", "created".
So my question is, does anyone know of a list of all fieldvalues keys?
Or is there a better approach to my problem?
Thanks
Update: Well, as I was iterating through the FieldValues collection any way. It was easy to do a dump of all the values to a CSV. Running it once was enough to get all the values. Now all I need to write is an xml file for configuration. This leaves the question: is there a better way of doing this?
Filter the list fields by writing following code
using System;
using Microsoft.SharePoint.Client;
clientContext.Load(
listItems,
items => items
.Include(
item => item["Title"],
item => item["Category"],
item => item["Estimate"]));

You can create an view with all fields, get the view using sharepoint object model and and get its column name from collection and filter them as per your requirement.
I have finished the application. As I wrote in my update I have made a list of all fieldValues by exporting them to a CSV file. After that I made a configuration-file with a boolean 'Backup'. This makes it possible to control which values are to be used when a backup is made.
I retrospect I think a configuration file was not needed. The values used when backing up are so much part of the whole workings of the program that a configuration file gives an administrator or casual future developer the impression that a simple reconfiguring will fulfill there needs.
I can now see that if the program needs to change due to new requirements the code has to be changed anyway. So even though setting a value to 'True' will change the output. Some other code has to be written as well. If I were to write it again I would probably use constants. This makes it all less dynamic, but still fulfill the needs of the program.
(BTW a list of all the names off the standard fieldValues would have been nice to start with. I would publish it here, but I don't have access to the file anymore, because I switched jobs recently.)
