I'm having some problems with people saving text files using my program, but only people using Vista. Since I don't use Vista myself, I'm not sure what this is but it's not a problem on any machine running XP.
Note that my file saves just using the standard Savedialog box and Filestream/Writeline commands.
From what my customers are telling me, the save dialog comes up fine and there is no error as the file appears to save, but when they look for the completed text file, there's nothing there.
Problem 1: I am running into a problem with my program that when UAC is active on Vistaaccess to C: and Program Files is not allowed. My program writes text files as a user types. Is there a safe place to write files to that may be some sort of standard instead of throwing files all over the place? Like maybe somewhere in the user's default folder's or something?
A query concerning opening and saving a file.i have two commands, one the opens and another that saves [the same file].i'm using the StreamReader and StreamWriter methods.issue is this:if i comment out the open code, the save works fine.if i comment out the save code, the open works fine.if i let both run together, i get an error, usually with the save saying that the file could not be accessed. note, before anyone asks, i do close the file after saving or opening what could be the problem? open works fine, because it usually happens prior to the save, and then save process cannot access the file..?
I have a VB.net applications that runs on XP and creates a directory and creates an Excell workbook and saves it. But when I do the same in Vista , when it tries to create a directory to save the excel workbook, it gives me an error that the directory does not exist. If I create the directory manually, it still gives me the same error. Is there a COM call for office 2007 on Vista other than worksheet.SaveAs(FileName:=path). All else works on Vista apart from creating a directory and Saving Excell Worksheet.
Public Function createDirectory(ByVal path As String) As String Dim new_path As String Try
i compile my form with the below code when i run it on vista work fine without any problem but when i try to run in on XP cant run... that happened with any XP machine.[code]when i run my exe to other Vista machines work fine... but on xp NO.
I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]
Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:
I am writting an application that stores data in an Access database. I can't put the files in the Program Files directory since standard users can't write to that folder. I can't use a 'user' folder since multiple users will need to access the same file. In addition to accessing the file, users on occassion will copy new versions of the file into the folder, overwritting the old file.Where should I put this file? I am thinking the ProgramData folder, but when I create that folder during the install, it is also read-only for a standard user.I'm lost as to where I should put a file that can be accessed by multiple users, that is read/write, and I can install the folder into the location. I don't think I have a programmatic way of installing a file into the Public users folder.
Ok I have a application that works great on XP, but in windows 7 it will not let me write to my login file, says access is denied since I am not running as admin. Log file is located in "C:Program FilesCompany NameProductMyLog.LOG"
I have encountered a small problem with my application due to the updater I built in.Basically the way the updater works is:1) Check for updates2) Download the new .exe file as "tmpMyApp.exe"3) Download "Rename.exe"4) Launch "Rename.exe" and exit application.5) "Rename.exe" then deletes the old application and renames the tmp one with the origional name "MyApp.exe"6) Launches "MyApp.exe"This all works completely fine for me, except when the program is installed in "C:Program FilesTinyGrab" this causes my app
ok, so i've built an application that iterates through some folders that i specified and adds any image files to a datagridview Image Columnhowever, .ico files pose an issue: ones that were specifically designed for WinVista Throw an Exception:"Paramater Not Specified"
I have a user of one of my programs reporting that they get an "access to the path...is denied" error during this section of [code]He's using Windows 7 x64 with UAC turned on. The location of "FilePath" is a subdirectory inside Program Files (x86) in this case.I tried to reproduce the error on my Windows 7 x64 system by enabling UAC (I usually have it off) but the program worked fine. However, in my case, "FilePath" is not in a protected system folder like Program Files (where write permissions are not given to normal users without admin elevation).So I tried to recreate this situation on one of my Vista x86 Virtual PCs where the "FilePath" would be inside Program Files. However, my program again worked fine. It had no problems writing to the Program Files folder with a normal user account, UAC turned on and no elevated permissions required.
Thus, I am confused. Why does it work for me and not for him? I want to try an x64 virtual machine but I can't with the software I have (Virtual PC doesn't support x64 guest OSs, VirtualBox won't run the software that my program interacts with). So maybe you guys can help me instead. Are the write permissions for the Program Files (x86) folder different between x86 and x64, or maybe even Vista and 7?
We have code in our former VB6 application, that ported fine to VB.NET, that plays a simple AVI file of the typical "flying folders" and "spinning maginfying glass" AVI. Under Windows XP, our application ran fine and everything was good.
Then we had customers start using Vista and Win7 and this stuff crashes. We were using the MS Common Controls (SP4) and then (SP6) - utilizing the Animation player. Now - these dont work and we get nasty errors.
I searched Microsoft and the web to answer the "what now?" question and though there are numerous suggestions, none of them work. We cant use Media Player because we dont want any menu - just the graphic. We dont know why, with the cool tools given in .NET, there is no animation player (seems a huge oversight...) But we need to get "unstuck" on this one, and we need that fast...
So, How does on play a simple AVI file using VB.NET code? What DLL or OCX does Microsoft recommend and is there a place we can find some sample code for it?
We have an application written with VB .Net (framework 2) that needs to run both XP and Vista machines. The XP machines have office 2003 while the Vista machines have office 2007.The application needs to generate reports as excel files. But when the files are created with xls extension the office 2007 in vista doesn't like the extnesion and gives a message before opening file about the file format.Is there a way to ensure through code that the correct file extension supported by the office version on the machine is used.v
Im working on an AutoUpdate class for a small application I've been working on, and with Windows 7 and Vista machines I get a permissions error when trying to replace some of the files in the Application folder. The only way to get it work is to run the application as an administrator. Is there a way I can either attempt to automatically run the app as administrator, or a way of replacing the files that won't be blocked by Vista/7's permission gatekeepers?
My application (vb.net) sometimes throws an "access denied" exception when attempting to delete files in the AppData folder and I'm not sure why.I confirm that the file exists before attempting to delete it and have not done anything to make it readonly, etcThe interesting thing is that it seems to go okay when I'm logged in with Admin rights
Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
Catch MsgBox("Selected Hero currently has no File with us.") End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.
I have a slight problem understanding how the following code works, it's specified in an example I have that the code is to check if FileName is a valid path for a text file and other things of course but I'm just interested in that part(checking it's a valid path). Here's the code:
I have a routine which populates a DataGridView. I generate the data on the fly in arrays and the populate the datagridview simply by saying
For each Row in DataGridView1.Rows DataGridView1.Rows(row.index).Cells("PastColumn) = Array(row.index) Next
I am not saving the data to log files. I only display the results at the end of my routine. When I close the project the data is lost.I am trying to understand why one would bind data. Would you do this in the case where you are saving the data to a file and you want the datagridview to update when the file is updated or loaded again at another time?
I am been working on an a small app that has a Forms.Webbrowser control that navigates to a Adobe Flash program. I have developed the app on Vista 32bit platform and have had no problems. I have sent the app to a couple of people to test out and one is using Vista 64bit and is running into a problem. I know the webbrowser control just uses the underlying base framework of IE. The problem on the 64 bit machine is when the site is navigated to it says that it needs to have Flash installed. When the user goes to Adobe's site it says they need to use a 32bit browser.
As stated on Adobe site here:[URL] the Flash player need to be in a 32 bit browser. What options do I have to be able fix this problem? Is there another control that I can use that would be the same in a 32bit platform and 64bit platform? Besides navigating to the Flash program, the browser also goes to standard web pages.
We have to learn VB.NET for the semester, my experience lies mainly with C# - not that this should make a difference to this particular problem. I've used just about the most simple way to save a file using the .NET framework, but Windows 7 won't let me save the file anywhere (or anywhere that I have found yet). Here is the code I am using to save a text file.
Any way to save all files that are being downloaded trough the WebBrowser I've made in my Visual Studio 2010 to a specific location, by letting user to chose option save file without knowing where it saves. Or maybe to don't show the "save file" thing at all.
what is the correct way to archive my work? That sound pretty dumb. Let me try again. I begin a new project and design a form and then start adding code then save my work.Tomorrow I want to make changes to the project an design - how do I save and keep track of my form and code versions?
I am working with .net resources using LINQ to XML. I want to edit some resources, so I coded this:
Public Shared Sub AddTranslation(ByVal filename As String, ByVal name As String, ByVal value As String) Dim items = From translation In XElement.Load(filename).Elements("data") Where translation.Attribute("name").Value = name
[Code]....
This seems to work, and even when I debug VisualStudio says that the file changed, but actually it doesn't. I think the problem is in the Save() action, but I don't know other way to save it...
