how it might be possible to only request the FileIO permission for the data directory created by clickonce? I want to run my clickonce exe from the web, but I only want to request the IO permission for the data directory where I am storing some user files. Unfortunately, I don't know the directory when I build the project.
View 4 RepliesI am writing a program to try and centralise alot of data i have on my network so i can use them as templates and guides. My intension was to have an easy to browse program with links in the program which open the particular file (eg. Word document, excel spreadsheet, pdf file etc).I have very limited programming knowledge and in my research i came across this code in VB which allows the program to open the determined file:
Public Class _010101ProgramTemplate
Dim procstart As New ProcessStartInfo("explorer")
Private Sub btnProgTemp01_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProgTemp01.Click
Dim winDirProgTemp01 As String = System.IO.Path.GetDirectoryName("g:Project Management SystemPMS TemplatesSetupProgramDD-IFC PROGRAM.xls")

View 3 RepliesI would like to query an Employee by matching First and Last name. Ideally, I'd like to be able to specify that in one EmployeeQueryRq QBFC object.
I think I have a start:
Dim EmployeeQueryRq As IEmployeeQuery
EmployeeQueryRq = requestMsgSet.AppendEmployeeQueryRq()
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.MatchCriterion.SetValue(ENMatchCriterion.mcContains)
EmployeeQueryRq.ORListQuery.ListFilter.ORNameFilter.NameFilter.Name.SetValue(LastName)
Is there any way I can add an additional NameFilter to the same request? Or am I stuck walking a response list for the other criteria (albeit a smaller one limited to containing at least one value)?
I don't know how to convert the nvarchar value into an int, but that is the way it needs to be set up. I've found other posts about this but I don't know how to use CAST in the INSERT statement I have. All the posts I could find were about converting to int in SELECT statements. I need this statement to change the field @Duration to an int in the database. @Duration is an amount of time. (01:00, 02:00...) They will all get rounded up to the next int value. So if a user enters 0:45, it should be converted to 1. how to get this INSERT to work?

I created a program which was deleting a particular directory for me. The program was compiled and working. Today I run the same program...did not do any system updates and now it won't delete my specified directory. I ran tests to make sure the directory is there when testing...I keep getting access/permission errors.
I rebooted system, ran my application...still gave me error. I turned off Windows Defender...still got error. If I manually delete the directory...no problem.
Is there a way to get system permission to delete the directory? I am being given an 'access denied' error...I do not have permission. I tried running my application as administrator...no good. - VB 2008 Express - VISTA OS

I have recently started using Request("key") instead of Request.QueryString("key") to access my querystring values. However I have read that:
'Gets the specified object from the System.Web.HttpRequest.Cookies, System.Web.HttpRequest.Form, System.Web.HttpRequest.QueryString, System.Web.HttpRequest.ServerVariables'
Therefore, if I have a querystring key and cookie key which are the same, which value is returned?
I'm using Visual Basic Express 2010 and SQL Express 2008 in Windows XP. At first I couldn't add a datasource (the .mdf file for the database) because of a "Operating system error 32" which I seemed to have resolved by giving myself full permissions for .mdf file (by right clicking on the file and going into properties and then Security) and restarting the SQL SERVER (SQLEXPRESS) service. The dataset for the database is in my solution explorer but when I right click on a table adapter to add a query and attempt to open up the query builder, I get the error in the title above.

View 10 RepliesI created a typed dataset a day or so ago, then I added a whole bunch of tableadapter/tables with some relationships etc... suddenly out of nowhere it decides my dataset "is not defined". everywhere in my code where i use this dataset now has an error. I tried not to pull out my hair and do a Clean then Rebuild solution... out of nowhere it just refuses to generate code. Object reference not set to an instance of an Object. It would be nice if it was my object so i could find it but it's not.
Curiously I also lost the little database icon on the dataset in the solution explorer.I can still open it in the designer and preview my queries etc... it just wont make the code. it's driving me insane. anyone got a solution?

My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.How can I get the regular key name working?
Visual example from the immediate window:I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
? request.Form("ctl00$content_innovation_body$stationIdea")
In my web application we have many users. I want to set permission for each user. In our windows application we used Database to store the Permission(Insert,Modify,delete and View). In web application can anybody tell me about where to store the permission. Somebody told that if we use database it will take so much time? In the case of XML it is easy and not taking much time. But if the client set permission for number of users,then it will create problem?.
(Permission means in case of "Category" page which user can view the Category page,which user can edit information about category,which user can delete information of category,which user can add new category)
Modifying a registry key we could 'write-protect' our USBs, and I wanted to make a program that would do such but I am getting a permission problem in adding a registry key to the local machine. My development machine is Windows 7 Ultimate 64 bit but I would want it that it will be able to run on other OS like XP and 32 bits. My thought is that I will use autorun and run my program so that upon insertion it will become 'write-protected' and be able to re-enable it also using the program.
