I am trying to store a value into a session like
Session("className") = lblBldgClass.Text
the above one is in ascx.vb file.
I want to use this value inside .vb file (not aspx.vb or ascx.vb) just .vb file
while I am trying to access this like:
bldg.cClassName = Session("className")
I am getting:
session not declared, it may be inaccessible due to it's protection level warning.

When I try to load my .NII file as a 4D Niimg-like object (I've tried both nilearn and nibabel),
I get the below error
Error: ImageFileError: Cannot work out file type of
"/Users/audreyphan/Documents/Spring2020/DESPO/res4d/1/res4d_anat.nii"
Here is my code:
ds_name = '/Users/audreyphan/Documents/Spring2020/DESPO/res4d/1/res4d_anat.nii'
block = nib.load(ds_name) #Nibabel
block = image.load_img(ds_name) #Nilearn
Both attempts result in the same error.
I'm not sure what's causing this error to occur?
Thanks!
It looks like the libraries are not able to extract the file type from your file.
So first of all we have to be sure that the file is not corrupt. Therefore, can you load the data correctly with a tool such as ITK-SNAP (http://www.itksnap.org)?
If yes, you can try to define the file type by your own in the nibabel package by using the specific loader function. E.g. you can try each one of the following loader functions:
img_nifti1 = nib.Nifti1Image.from_filename(file)
img_nifti2 = nib.Nifti2Image.from_filename(file)
Oddly enough, this error also occurs when the access permissions are not set appropriately for the file you are trying to load. Try using chmod to change those access permissions appropriately and then loading the *.nii file.
I am dynamically creating a File in the workspace and trying to generate a IFile instance of it.
IPath location= Path.fromOSString(file.getAbsolutePath());
IFile iFile=ResourcesPlugin.getWorkspace().getRoot().getFile(location);
FileEditorInput input = new FileEditorInput(iFile);
but when I try to see if ifile exists or not (using iFile.exists()) it gives false.
I tried using canonical path as well but that also did not help.
Changes to the file system are not automatically detected by the Eclipse workspace, you'll need to tell the workspace to refresh its view of the local file system. You can do this with:
iFile.refreshLocal(IResource.DEPTH_ZERO, null);
If more than one file has changed you can do the refresh at the folder level changing the depth.

What am I doing wrong?
Should I completely eliminate this File System Task and replace it with a C# Script Task to copy the file?
Is there something obviously wrong with my process?

the properties page is asking for a variable name and you are providing a file path. Do you have a variable in your SSIS package that can hold the fully qualified file name?
Your SourceVariable property (in screenshot #2) should refer to your a variable name, not the actual value of the variable.
I'm seeing an issue with an SSIS (SQL Server 2005) job where I'm getting the following error:
The file name "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=\UNC\FOLDERS\filename.xls;Extended Properties="EXCEL 8.0;HDR=YES";" specified in the connection was not valid.
My searching around this site and others indicates that the most common cause of this is a permissions error but I don't believe that's the case in this situation since any number of files have successfully been processed through this implementation.
Here's an overview of the setup:
Vendors FTP files to us on a daily basis that a Windows service picks up, copies to a temporary directory and then calls SSIS jobs on those files. There are two SSIS jobs for each vendor one for a snapshot data feed and one for a transaction listing.
There are currently over 50 different SSIS jobs in the overall process. All of them work except for one specific transaction job which fails with the above error in a script task step. Files come in at least daily with unique file names so I grab the job, determine the vendor based off the source directory and then the file type based off indicators in the file name to determine which SSIS job to call. Since file names change every day, when the service calls the SSIS job, I pass in a series of parameters including the vendor file name so it can properly connect to the file.
Each job begins with a script task that sets necessary variable values for the rest of the job. For example, since the vendor file name changes with each run, I pass in the vendor file name through the SSIS variables collection then set the connection string of a datasource using that file name as the DataSource in the string. It is at that point of the script task that the above error occurs. Here's the task script code where the error occurs:
Dts.Connections("Transactions File").ConnectionString = _
Dts.Variables("ConnectionString").Value.ToString().Replace("##FILE_PATH##", sourceFilePath)
The ConnectionString value is: Provider=Microsoft.Jet.OLEDB.4.0;Data Source=##FILE_PATH##;Extended Properties="EXCEL 8.0;HDR=YES";
The sourceFilePath is the full UNC path to the vendor file in the processing directory
I don't believe it's a permissions error since all the other files going through this process (using the same holding directory for processing) are working. It shouldn't be an issue of the file not existing since again it follows the same process as every other file and I have verified the file properly ends up in the correct directory. I also considered that the connection string might be too long, but the filepath ends up at 109 characters and even with a shorter (<90) full path, the same error occurs.
Is there anything else you can you think of for me to look at? Thanks for any help.
Based on the information presented, you are doing everything correct. If you're new to SSIS, one thing I'd suggest, is that you get a copy of the excellent add-in BIDSHelper. It has great features that can really save you time especially with regard to configurations and expressions.
I created a reference package that had an Excel Connection Manager pointing to C:\ssisdata\so_paulsmithjr.xls and wired everything up.
At this point, I know things are working so it was time to make the package move. I created the following variables and their values
CurrentFile - C:\ssisdata\so_paulsmithjr.xls
PlaceHolder - ##FILE_PATH##
TemplateConnection - Provider=Microsoft.Jet.OLEDB.4.0;Data Source=##FILE_PATH##;Extended Properties="Excel 8.0;HDR=YES";
A fourth variable is set to be an expression (Right click on variable, properties window. Set Evaluate as Expression = True & Expression is below)
CurrentConnection - REPLACE(#[User::TemplateConnection], #[User::PlaceHolder], #[User::CurrentFile])
I compared the CurrentConnection value to the ReferenceConnection (which is the original value of the Excel Connection Manager's connection string) and things were a match. At this point, if I were to change the value of CurrentFile to C:\ssisdata\so_paulsmithjr - Copy.xls, that would automatically be reflected in the value of CurrentConnection.
The final trick would be to use an Expression on the Excel Connection Manager. Again, right click on the CM and under Properties, there will be Expressions. It won't expand as there is nothing under it. Instead click the ellipses and then select ConnectionString property and select the ellipses again and this time drag down the #[User::CurrentFile] variable. Click OK x2 and now your connection manager is set to use wherever the CurrentConnection variable specifies.
Does that work any better?
for some test I need to run a data driven test with a configuration that is generated (via reflection) in the ClassInitialize method (by using reflection). I tried out everything, but I just can not get the data source properly set up.
The test takes a list of classes in a csv file (one line per class) and then will test that the mappings to the database work out well (i.e. try to get one item from the database for every entity, which will throw an exception when the table structure does not match).
The testmethod is:
[DataSource(
"Microsoft.VisualStudio.TestTools.DataSource.CSV",
"|DataDirectory|\\EntityMappingsTests.Types.csv",
"EntityMappingsTests.Types#csv",
DataAccessMethod.Sequential)
]
[TestMethod()]
public void TestMappings () {
Obviously the file is EntityMappingsTests.Types.csv. It should be in the DataDirectory.
Now, in the Initialize method (marked with ClassInitialize) I put that together and then try to write it.
WHERE should I write it to? WHERE IS THE DataDirectory?
I tried:
File.WriteAllText(context.TestDeploymentDir + "\\EntityMappingsTests.Types.csv", types.ToString());
File.WriteAllText("EntityMappingsTests.Types.csv", types.ToString());
Both result in "the unit test adapter failed to connect to the data source or read the data". More exact:
Error details: The Microsoft Jet database engine could not find the
object 'EntityMappingsTests.Types.csv'. Make sure the object exists
and that you spell its name and the path name correctly.
So where should I put that file?
I also tried just writing it to the current directory and taking out the DataDirectory part - same result. Sadly, there is limited debugging support here.
Please use the ProcessMonitor tool from technet.microsoft.com/en-us/sysinternals/bb896645. Put a filter on MSTest.exe or the associate qtagent32.exe and find out what locations it is trying to load from and at what point in time in the test loading process. Then please provide an update on those details here .
After you add the CSV file to your VS project, you need to open the properties for it. Set the Property "Copy To Output Directory" to "Copy Always". The DataDirectory defaults to the location of the compiled executable, which runs from the output directory so it will find it there.
