FileName As String - Application Installed Randomly Locks Up
Dec 23, 2010
I have a quite simple application that is having some random locks up. It's just a few text fields that the user fill it up, 3 sets of Radio buttons, one of them with flags to chose the language and click the PDF button. The application uses iTextsharp to load a PDf template, insert the text into it, depending on the language loads some extra text from a .xml file, and depending on the radio button removes the images from the PDF, closes the pdfstamper and uses [Code] to open the file with whatever PDF application the user have installed and closes itself.
Sounds simple, but after the application is installed in the machine (never in debugging mode) it randomly locks up the application. I tried re-publish the application commenting out the Start(filename) line and the thing stopped locking. And I double checked it, re-publish with the line again and it locked after just a few attempts. [Code]
Quick query...I'm trying to scan a long string and return any values that occur between the tags <FileName> and </FileName> I've got a bit of code here to use regular expressions to return the position of the occurunces of both substrings..Just wanted to find out if there is any way to scan for both substrings within one loop (as im currently doing 2, one for the first substring and one for the 2nd) so I can use something along these lines:
to msg box the value between the substrings...either that or another approach to return the value between the 2 substrings (it can be of variable length)
Dim patternstart As String = "<FileName>" Dim patternend As String = "</FileName>" Dim matchesstart As MatchCollection = Regex.Matches(XMLRESP, patternstart)
I develop windows applications in VB.NET using Visual Studio 2008. Recently I reloaded my pc and moved from XP to Windows 7 64 bit. Now when I am debugging, when I should get a runtime error, the executable instead locks up when it should bring up the code with the line that it crashed on like you'd expect in debug.
This doesn't happen all the time, only when I get a runtime error in a separate assembly that is not in the assembly I'm debugging. It used to work fine, but now it locks up. If I run the executable outside of Visual Studio (without debug) I at least get a runtime error like you'd hope for. I don't even get that when debugging.
I have a Windows Forms application created in VS2005 which runs fine on the user desktop but when running in Terminal Server session it frequently locks up when the remote desktop window is minimised and the user is working locally.There is plenty of RAM on the server so this is not an issue, the only solution so far has been to force the user session to log off on the Terminal Server and then reconnect.
I'm have a quite big application which have 2 serial ports and access 1 DB (running on Background workers). I'm experiencing some random locks while the application is running and I started looking for something that could cause it. One of the obvious possibilities would be if I had in the GUI thread some While_End that would never return.I have one While_End in my GUI thread but IMHO it does not look like it would lock, so I want your opinion: Does the code below looks like will lock?? If 'yes', Why ?
[code]...
Does anyone can imagine a scenario where this While_End would not return ?
I have a do until loop. But whenever my program get's to it, it always locks the application so I can't click on anything until the loop is finished. How do I fix this? I want to be able to stop the loop with a stop button.
I have a form with one richtextbox and one button. The idea is that: Form Load: data read from text file into arrayButton Click: random number generated, then used to select the string whose index number matches the random number generated
My StreamReader is working correctly and I can create random numbers with no problem, but I'm stuck on how I can use this random number to extract the corresponding string. I keep get the error saying QuoteObject reference not set to an instance of an object.
My code is below: Imports System.IO Public Class Form1 Dim questions(69) As String Dim i As Integer [Code] .....
I have created an shareware application using vb.net visual studio 2008 for windows desktop, and packaged it using innosetup 5.3.8. The problem is when i have installed the application in C:Program FilesApplication and it runs successfully(use trial period of the application), Im also able to install the application once again freshly with the same setup by installing in different directory.eg C:Program FilesApplication new . The application in C:Program FilesApplication new does not have any settings of the already installed one.
Where do i went wrong . Do i need to take care of this in my application(vb.net) or innosetup. How to take care of the already installed path in innosetup or carry the settings of already installed application to newly installed path by upgrading the older one.
I dont want to write any thing in registry because the application does not want any administrative permission requirements.If i install the application in same path it gets updated with the older settings being taken over to this new one and it works fine.
I have designed and published my small created app with WINDOWS FORMS using VB 2010 EXP on Windows 7. I can only install the app on the machine that I used to develop the app.I want to install the app on another computer but I cannot. I usually have error reports.
Example:Unable to install or run this application. This application requires Microsoft Common Language Runtime 4.0.3 to be installed on your computer.
what can I do to be able to install the app on a different computer which does not have .Net and does not have visual basic 2010 installed.
I'm using VB 2010, and am trying to add a simple TTS function to my program. I'm able to create a voice object, and get it to speak (Voice.Speak("whatever") with no difficulty.
The problem I'm having is that while the "whatever" is actually being spoken, the program doesn't seem to respond to input. The input does show up once the audio is through, but I really need to be able to detect some input (say, a mouse or button click) during a message and respond immediately, perhaps even stopping the audio.
I have recently created an application with Visual Basic.NET. I published my application and installed it. Now the question is that I need to know where exactly does the application gets installed on my system ?
I am trying to make a filename something like this:
dim Test as string = "name_" + now.toshortdatestring() + ".pdf"
The datestring is like MM/DD/YYYY, which is a particularly bad filename (who want slashes in their file names??)Is there a way to format the date string differently (ie MM-DD-YYYY)?What I was trying to do is tag the file with a date so I could tell when the last time that file was generated, and also keep multiple copies around for archive purposes. Maybe there is a better way and then I dont even need this differently formatted string?
How would I do that? Sample code is below that demonstrated that the file I opened contained the full path and file name.
I want to extract just the path and serialize that to the user.config file as a UserSetting value. Then next time the user opens the dialog box, it uses that saved path string to go immediately to the location previously used.
If openFileDialog1.ShowDialog() = DialogResult.OK Then Properties.Settings.Default.persistConnectionType = openFileDialog1.FileName Properties.Settings.Default.Save();
I have a userform in 2008 vb express edition. A part number is created from user input via a concat string. I want to then check if a certain portion of the part number exists in the existing file names in a directory. Below is a more detailed explanation.[code]...
I have a piece of code to debug. Because of unknown bugs it creates a dummy filename. I want to track all the pieces of code who fires that creates the dummy filename, so I can change the dummy file creation to a thrown exception. Since I the dummy filename is stored on a string, I plan to modify that string to contain an invalid NTFS filename, maybe containing invalid chars. Is there a reason to prefer some invalid chars over others? There are some predefined invalid NTFS filename destined to this purpose? (I may think of AUX , COM1 , LPT1 or PRN , but those names run the risk of start sending data to a port instead of throwing an exception).
Public Sub saveExcelFile(ByVal FileName As String)Dim Excel As Object
[Code]...
that is my code. everytime i open the saved file, it says that it has a different file type and asks me if i want to continue opening it and i click yes. the data inside the excel file is only the word "Success"
I have a Listview on my form with different files. I can selet a file en open it with the proces start method. To open the file i use the OpenFileDialog method and select the filename. This work very good. With the code below.
My question is if there is a method to get the selected file without using the OpenFileDialog Box. So when i dubbelclick the selected file the proces will start with open the selected file. Something like:
proc.StartInfo.FileName = Me.SelectedCell.FileName instead of proc.StartInfo.FileName = Me.OpenFileDialog1.FileName
PS) May be i can preduce the Filename using the OpenFileDialog method on the background.
Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick If Me.OpenFileDialog1.ShowDialog() = Windows.Forms.DialogResult.OK Then
i published an application in vb.net. the user will be able to install the application anywhere they choose on the computer (or perhaps not anywhere they choose but where ever the default location is). how can i programmatically get the location where the user installed the application? another words i need the application to know where it is running from. how do i detect that?
I know the default install path of the app and the name of the .exe file, but is there a way to see if it is actually installed? I've seen suggestions for checking registry entries, but I don't know if this app uses any or if if varies for different users on different pc's.
I am trying to install a program but I get the message Application already installed at other location The application does not appear in the program manager to be uninstalled. I have tried publishing a later version but when I try to install it I get the same message. The click-once publisher generally includes an uninstall program with the applications. when Ive had this problem before it was fixed by republishing as a newer version.
I have a very old plug-in software developed in Visual Basic quite years ago, now its getting time to modify the copyright info. At this point, the issue is now that I was not the author so I don't know anything about it.
I have updated the source files which includes a SLN, VBP, WIP, MSI and so on, then I tried to use VS2008 to open the SLN file and after Conversion it given me a message "The project for XXX.wip is not installed, please make sure the application for the project (.wip) is installed", Apparently this is not right version to get going on. Can everybody tell which VS version can proceed it? or any idea how I do this?
I have started working on the module based application (plugin based architecture) and client want setup of module that can be run later and added automatically in main application. So, what I am thinking to apply in module setup project is to find the installation directory of main application and then paste dll of module in specific sub-directory.
Is it possible? Is there any other way to add feature in main application later using setup?
I need to get a list of installed program on local machine with application icons. Below is the code snippet that am using to get the list of installed program and installed directory path.[code]....
