I've posted this question in asp.net web forum but no one replied.
I can't open "ONE" page of .pdf file using IE8 and give me an error message "the file is damaged and could not be repaired" when retrieved from SQL Server 2008, but more than one page I can open with no problem.
With Chrome I can open any number of .pdf pages.
The same page that I can't open using IE8 from DB, can be opened directly from hard disk using IE8.
My code in .asxh file:
context.Response.ContentType = "application/pdf"
Dim strm As Stream = ShowNewsImage(imgName)
If Not strm Is Nothing Then
I have a Motor Class, along with a Collection to hold objects address. Each Collection object holds the Class fields as a String to display in list box. I am able to write the collection string to the file and save the string. But unable to open the existing file, read the file back into the collection object.
Public Class Motor Private strId As String Private strDescription As String
[Code]......
I have looked all over for anything (samples or tutorials for working with files and collection objects) pertaining to type of operation with out any success.
I'm getting this error message when I try and run my program:
[Code]....
I have run this program man times before. I just added a Windows Form InputCrossForm.vb to my project. When I dbl click on the error message I get a message box title bar "Microsoft Visual Basic 2010 Express" with message "The definition of the object is hidden." Not sure what this means nor what to do to fix it.
I am writing a program that acceses a file in VB/Visual Studio 2008 on Win7 and running it as a user who has admin credentials. I am opening the file with the following code:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None) To test to make sure I can't access this file, I tried to open it with Notepad and I was able to and got no errors. I wrote a new value using Notepad and even saved it and I didn't get any errors form Notepad or my VB program.
I then went on and treid to open the same file twice from my VB program as:
Dim Input As New FileStream("C:FileTest est.txt", FileMode.Append, FileAccess.Write, FileShare.None) Dim Input2 As New FileStream("C:FileTest est.txt", FileMode., FileAccess.Read, FileShare.None)
And I receivded an error in my VB program as expected. So the FileShare.None switch kind of works. Although I was still able to open the file with Notepad while my VB program had it open. I was aslo able to open Windows Explorer and reame it and even delte it while my VB program had it "open", in the write mode no less without my VB program knowing anything about it.
Why are other applications able to ignore the FileShare.None switch? Seems pretty useless if that's the case. And a huge secruity problem
I am working in Visual Studio with a solution containing multiple projects. The solution is based on a co-worker's computer. I am trying to build the project, I get the following error:
Error 17 Unable to open module file 'C:DocumentsVisual Studio 2010Projects ReportCreatorMy ProjectApplication.Designer.vb': The system cannot find the file specified. C:DocumentsVisual Studio 2010ProjectsBlahBlahBlahReportCreatorMy ProjectApplication.Designer.vb 1 1 ReportCreator
It is on my co-worker's computer, but I don't see it in source control. He has ReportCreator checked out. How do I create Application.Designer.vb?

I am getting the following error when trying to open a vb .net 1.0 project using VS2002."Unable to open Web project 'ProjectName'.The file path 'FilePath' does not correspond to the URL 'ProjectURL'. The two need to map to the same server location. HTTP 404: Object Not Found."I have tried ALL of the links that Google threw at me (on the first page) on searching on "unable to open web project the two need to map to the same server location" term.I get this error when trying to open an existing vb.net 1.0 project and also when creating a new one.
I'm running windows vista. I get the upgrade for sp1 via windos auto updates. I then it adminstration by right clicking on the shortcut. I open up visual basic, I can't open my projects.I can click on the link, do it via file. None of the files will load up or open.
I have installed all of the patches and Hotfixes that I can find and truth be told, this is so enigmic that i dont know where to go to.I have been working on a project for a year and just recently I went to add a database (data source) and the Tab was gone. I thought I did something wrond so i went to Data -> Data Source and nothing happens. whats funny is that I cannot do what I want and add the datasource.
I also have VS 2005 installed (which I am forced to use) and here I have no problem.
Can anyone or does anyone have a simular problem and a resolution??I really would love to use all that is available in VS08 and not having to use a much older version...
I get the error "35750 unable to open internet handle" from a server running a Visual Basic 6 program using the Inet control to access a site. It used to work but now it stopped. What is causing this and how do I fix it?
So there I was working on a project. I was putting the finishing touches on the GUI and clicked on the Image list I had added. VB froze up a moment, and when it came back I was on a code view of the form showing the properties I had just set up in the GUI. Suddenly, I can in no way view the form. I get a View code option, but no View designer. If I close out the project and open another, there it is "View Designer" right where I expect it. But in the project I was working on, it is just plain gone.
Is there something I am missing here? Can I recover my project?
If I run it in the debuger the whole form shows perfectly, I just can't get to it to edit it.
Having just downloaded the Visual Studio 2010 Ultimate Beta, I decided to code from scratch a little project I coded under 2008 VB.Net and see how it goes. However, when I click on "New Project", select new Windows Form Application project and try to open it, I get the following error dialog box & msg:
"Unable to cast COM object of type 'System.__ComObject' to interface type 'Microsoft.VisualStudio.Editor.Implementation.IVsGlobalUndoCapableUndoManager'. This operation failed because the QueryInterface call on the COM component for the interface with IID'{305E8709-55B7-4732-B872-1C073AB58047}' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002 (E_NOINTERFACE))."
Anybody have any ideas what's up here, or should I post this in a different area? I tried posting this in the Microsoft MSDN Visual Basic IDE Forum but so far I have not received a reply.
I have a VB.NET application that will let me preview .DBF files that come in from some of our clients. The application then attempts to spit out a CSV from this file that we can then use in our various environments. This application worked under Windows XP 32 bit. Our company recently upgraded most of us to Windows 7 x64 which has caused this application to fail. I verified that the target build for this application is x86 and not "any CPU" and rebuilt the app but same issues occur.
It originally used System.Data.Odbc and connection.ConnectionString = "Driver={Microsoft dBASE VFP Driver (*.dbf)};SourceType = DBF;SourceDB=" & dbfSourcePath & ";Exclusive=No; Collate=Machine;BACKGROUNDFETCH=NO;". The location of the failure is at connection.Open(). The error given is: "ERROR [IM001] [Microsoft][ODBC Driver Manager] Driver does not support this function".
I noticed that the drivers for VFP were not installed and that the Access DBF drivers did not work similar to the post here. The fix listed there is to install VFPro SP2, however, we do not have any FoxPro installs to install a service pack on top of. I then tried to install the OLEDB driver for VFP 9.0 and am now using System.Data.OleDb and connection.ConnectionString = "Provider=VFPOLEDB.1; ourceDB=" & dbfSourcePath & ";" but it now tells me that the connection.Open() line has this error: "Feature is not available".
I am at a complete loss as to how to get this application to work under Windows 7 x64. Below are the 2 variants of the code with the file open path removed for readability (I have verified the path and file exist):
ODBC version:
Imports System.Data.Odbc Dim strSelect As String strSelect = "SELECT * FROM " & dbfSourceName
[Code].....
How can I use either an OLEDB or ODBC connection to open these .DBF files under Windows 7 x64?
I am using a IE browser in my application with IE8 installed.When i right on a link and open with new window, new window is opened but the page is not loaded. But the address is shown in the new window url box and when i click enter in the url box, then page is loaded. I didn't see this issue in IE7. I face this when i using IE8 in WinXP or Win 7

Why would a .sln solution file open and appear empty in Microsoft Visual Basic 2010 Express - i.e. no windows showing projects and code files etc.When I inspect the file in a text editor, it contains references to vbproj files (which are present) which indicate that it should not appear as empty.No error messages are reported when the file is opened.
I would like to open the excel file after create the excel file. The creating file function is done, but the system unable to open the excel file. My coding as below:

I've noticed that when you click on a web page in Windows Explorer, or open a file in general, and the default application to open it is internet explorer, ie opens and opens the file. However, when I tried this on my Web Browser it opened, but ignored the file and went on its usual routine. How can I get my Web Browser to open and open the file that was clicked on in explorer?
I saved a file with the extension .doc. I use the RichText to write and save the text. I did not set any encoding type when I saved it. When I tried to open the file in the Richtextbox again, I got all the formatting characters in the RTF file. How do I correct this? How do I open and re-open a .doc file in the Rich Text box control without the formatting showing up in the box with the document contents?
