.net - Error Accessing MQs From .NET?
Mar 15, 2012
I have a VB.NET console application that must write a message onto a queue (resides on the mainframe). We have all the clustering and everything set-up by our admin. We already have an existing windows service that successfully listens to messages and also writes messages to various queues.I have basically re-used most of my code from the windows service project.But when I try to access the queue manager, I hit the exception "MQRC_HOST_NOT_AVAILABLE". The error log from the Websphere MQ folder says
AMQ9213: A communications error for occurred.
EXPLANATION:An unexpected error occurred in communications.
ACTION:The return code from the call was 0 (X'0'). Record these values and tell the systems administrator.
Here is the complete exception stack.
IBM.WMQ.MQException was unhandled
Message="MQRC_HOST_NOT_AVAILABLE"

Here is the error: "Le thread appelant ne peut pas accéder à cet objet parce qu'un autre thread en est propriétaire." (Translation : The calling thread cannot access this object because it is owned by another thread)

I've got a problem whereby I get Permission Denied while accessing a database via OleDB. I know how to unlock this but i'm not permitted to do so. I was wondering if ODBC would work? I'm not sure on the settings around this on my the PC where I'm going to use this application but wonder if this has less security around it. your thoughts until I can test this next week. Or is there another way you may know that I can use a database. (access)

I have developed a website that allows users to upload office documents then uses the office object model to convert the document to an HTML file that it then displays in an iFrame. I have, of course, included references to Office.interop.word, and the site works fine on my development machine. When I uploaded it to my production server the site functions fine until I try to upload a document. I initially got a similar error that said "COM object not registered". I realized that Word wasn't installed on my production server. So I installed word and now when the server tries to access the word object model I receive the following error:
Retrieving the COM class factory for component with CLSID {000209FF-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))
I searched the registry for the corresponding CLSID and found a corresponding folder. I added full control to the IUSR_ account and due to the persistence of the error I eventually added full control to "everyone" and ensured these permissions inherited down to the rest of the folder. I then added full control to IUSR_ and again eventually added full control to "everyone" to my microsoft office folder.
I don't know what other permissions to grant and where in order to make this "Access is denied" error go away. I must be granting them in the wrong place, because as far as I know I can't be any more permissive than "Everyone" "Full Control".

Basically in visual basic 6 I could access word tables in existing templates with the code owordactivedoc.tables(1).select() where owordactivedoc refers to the active word document and tables(1) refers to the first table in the template.Trying the same code in VB 2003 just leads to errors. Secondly how do I access bookmarks or alternatively word variables.Furthermore how do one deploy web.services. For example the current program I am building is for another computer. Simply copying the web service to Inetpubwwwroot dont work because it is not picked up by the Internet Information Services program. I have to create the web service in vb2003 on the other computer change msconfig manually. Copy and paste the existing service vb file in the created folder replacing the empty vb file.

I have an ASP.NET (C# Code-behind) code. I need the very same functionality in one of my VB 6.0 program. As the code is too complex, I don't want to replicate it in VB once again.
Now, is there any way to access my .NET code from VB?

myObject.rect.X = 100
myObject has a property called rect (which is a Rectangle). During runtime I will want to chage the X position of such rectangle, but I am given this error:
Expression is a value and therefore cannot be the target of an assignment.
Then, how am I supposed to change such values?

I have two variables, X and Y (this is just figurative)
X = 123
Y = X
How can I get that X out of the Y to be able to get the contents of X from the Y? I just want to be able to do something like tell a textbox to display the contents of the variable within the Y variable (thus, the contents of X).

What I want to do is have my vb .net program open ms word and put an address into the envelope wizard this way the user can go from there adjusting the envelope size etc. In ms word 2007 I have found that if you hit alt, then 'm' then 'e' it will open the wizard and put the cursor in the right place to type the 'to:' address.Current I can open word and put the address directly into the new document.Here is what I have so far:
Dim oWord As Word.Application
Dim oDoc As Word.Document
Dim address As String
oWord = CreateObject("Word.Application")

I read a an array of bytes from a file I pass this to a class that then assigns various bytes from that array to various members of varying sizes.
Ideally i would like to do something like this
memberThatIsAUShort = bitconverter.ToUShort(tempArray.subArray(3,5))
memberThatIsAShort = bitconverter.ToShort(tempArray.subArray(6,8))
Instead of looping through the array, copying the bytes to new shorter array and passing them in.

I've an application that's uploading data to a server. Occasionally the server returns a 403 response from a call to HttpWebRequest.GetRequestStream(). The response contains more data than simply the response code, but I can't figure out how to access it. Is there a way to do this?

I need to show a grid of saved projects (compare "orders") in a datagrid, where the projects are saved in an Access 2000 database with a similar schema as follows:
ID Name Country_ID Plant_Type
1 'Test' 1 1
2 'Second' 2 2
Let's call the file "Projects.mdb". This is then showed in the datagrid as:
ID Name Country Plant Type
1 'Test' 'Germany' 'Free Range'
2 'Second' 'France' 'Inclined Roof'
where the countries and "Plant Types" are fetched from a different table in a different .mdb file (also Access 2000, call it "Language.mdb", although there is a lot of different background data in it), depending on the current user's language preference. It is unfortunately not an alternative to merge these .mdb's into one file.
To be able to show the datagrid I have so far linked the tables from "Language.mdb" into "Projects.mdb", but this screws up when the project is being installed on another computer with the .msi file i created (we'd like to have this easily packaged and installed), as the "Language.mdb" doesn't exist on the linked path on the target computer (Basically the problem here).
I can come up with the following solutions:
Force all users to install on the same path, so that the links will work (undesirable)Use connection strings in the query as shown here on MSDN (still trying this out, but I need to work on the details)make a post-install script that relinks the tables according to the correct path.

I have a sqlDataSource that runs a stored procedure that returns a table of the days of the month that was passed in as a parameter, arranged as they would in a calendar. It also returns a second table which contains the event details associated with certain days of the month.Basically, how would I go about accessing the values contained in the 2nd table that is returned by my query?I have tried putting the result of the .select in a dataset, unfortunately I get a cast error. If I try to put it in a dataview, I only get the first table.[code]

I am currently working on a project for school. I have the project all laid out in my mind and everything but there is one thing that stops me. I can not access the data from the database itself ...
(detailed info)
I am using an AMD Athlon x64 bit processor with a windows vista 64 bit operating system. I am writing the program on visual basic 2008 express edition. When I open up the visual basic 2008 express edition and create a new project the first thing I do is go to the view menu and activate my database explorer. I connect to the database in question through the database explorer. The database I am connecting to is an access 2007 database (ive opened up the access 2007 files and they do open and display information properly, in otherwords, they do work) I then put in a listbox and use the following lines of code in a form load event to both A) create the datatable and B) automatically fill the listbox with the database info.
Dim dt As New DataTable()
Dim connStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & _
"Data Source=MEGACITIES.MDB"
[Code]....
When I test the program the listbox does not fill up with any information from the MEGACITIES access 2007 database. Ive tried connecting to the database by establishing a connection through the datasources window. Ive tried establishing a connection to the database through both the database explorer and data sources window. No matter what I try I can not get that information accessed.
Im almost confident that this has to do with my processor being 64 bit.
