System Windows Forms Application StartupPath In WPF
Jun 12, 2011
i have one window application developed in VS 2005 which is running successfully on client side,My question is that now i want to convert this window application in WPF browser based application, so what should i keep in mind to convert this application to wpf applicaton, One more thing that in Window Application i have used one mdb file which contain database login detail, so on application startup this file is accessed using System.Windows.Forms.Application.StartupPath+@"/filename.mdb", now im just want to test only whether can i login to my application using WPF or not this time it give me this error "Request for the permission of type 'System.Security. Permissions. RegistryPermission, mscorlib, Version=2.0.0.0, Culture=neutral".
I have a windows forms application written in VB.NET which scrapes information from serveral web pages (who doesn't right)? Anyway, I am having problem with one particular site where partway through the page navigation my application hangs. When I press pause (or break) in the debugger, it stops on a call to System.Windows.Forms.Application.DoEvents.
Resuming execution shows that it really is stuck on this line (it does not reach the next line of code). It also hangs about the same point each time I run it (at least its consistent). Since System.Windows.Forms.Application.DoEvents yields to other threads on the same processor and then resumes execution of the current thread, I think the problem is that some other thread is not behaving well (not returning from some event handling code). I thought Windows 7 was pre-emptive, which makes me doubt that theory but I really don't know.
[Code]...
The program scrapes somewhere between 12 and 14 pages before it gets stuck on the call to DoEvents. Does anyone have a clue why this would happen? Why would any call to DoEvents hang?
I have the code which checks if there is a selected tab
Private Function GetBrowser() As WebBrowser If TabControl1.SelectedTab IsNot Nothing Then For Each c As Control In TabControl1.SelectedTab.Controls If TypeOf (c) Is WebBrowser Then Return c
I grabbed an example program to modify for my needs to grab data from a Word doc and transform to XML. Right off the bat I get multiple errors. [Code] I am getting Error Type 'System.Windows.Forms.Application' has no constructors.
I am adapting this code from excel vba to a Visual Studio program I am writing that will list files that are relevant to given information. I keep getting an error about filesearch not being a memeber of 'system.windows.forms.application' on line fs = Application.FileSearch, I have read and saw that I should be using the DIR function...
Sub SearchForForms() Dim fs As FileSearch ', ws As Worksheet, i As Long Dim SearchFileName As String fs = Application.FileSearch <~~~ ERROR[code]....
We just spent 300 man-hours fixing a buggy application in the field. It all came down to calling Application.DoEvents (re-entrancy problem).This was not caught in design reviews, code reviews.The code was inserted two years ago with the first version; the application was always "flaky" but recent changes exposed the re-entrancy problems to a greater degree. This incident is the second time in our organization that Application.DoEvents caused failures and multi-man hours of debugging.It was discovered in this case by simply noticing the call,buried way down in a complex event handler for an asynchronous task.What do you suggest to prevent this issue from happening again:
Add checkin gates to source control?
Developer training?
Code Analysis rules (why is this not already a built-in rule?)
I have a panel with some controls in it (several textboxes, a slider, 2 buttons, and a small groupbox).. When I click a button, I want all of the textboxes within the panel to be readonly... So I have this code: [code] When I run it though, I get the following error:Unable to cast object of type 'System.Windows.Forms.Button' to type 'System.Windows.Forms.TextBox'.If I remove a button, it moves on to give me the same error but for a label..
An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll it also says make sure you do not have infinate loop or infinate recursion il give all code in order that they are executed in Check the chechbox and it disables all irelevent stuff and populates the combobox

I get this: Base class 'System.Windows.Forms.Panel' specified for class 'MenuButton' cannot be different from the base class 'System.Windows.Forms.UserControl' of one of its other partial types.
Win7 64 bit; fully patched VS2008 targeting FW2.0; VB.Net; running in Debug Mode (not tested in Release mode)I have a resonably complex app which I am refactoring a bit. As part of that, I relocated some code from a subroutine into a Click Event Handler. The Event Handler will, late in the handler, call the, reduced in function, subroutine. The point of this is thatNow when I click the button associated with the modified Handler I get:A first chance exception of type 'System.AccessViolationException' occurred in System.Windows.Forms.dll<br />With Error System.AccessViolationException Attempted to read or write protected memory.This is often an indication that other memory is corrupt.

[code].....
All functions of the app, except those that start from the buttonclick in question, work as before in the problem version.The problem persists after rebuilding the entire solution, after restarting VS, and after rebooting the PC.
When I run my project I get "An unhandled exception of type 'System.StackOverflowException' occurred in System.Windows.Forms.dll"

I have the following code running, the first time I change the selected index, everything runs smoothly. However, if I try to change the selected index again, nothing happens and the subcategories combobox values do not change.
Private Sub cboMainCategory_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboMainCategory.SelectedIndexChanged '* make sure the combobox is fully loaded
I keep getting an eroor this error says: An unhandled exception of type 'System.ArgumentOutOfRangeException' occurred in system.windows.forms.dll Additional information: Specified argument was out of the range of valid values.

A first chance exception of type 'System.InvalidOperationException' occurred in System.Windows.Forms.dll It displays in my Immediate Window when i run my program, I'm using a text reader to read a number of XML files using background worker...most the time it stops so something is wrong but sometimes it works fine.
I am working on a card game, and i get this werid error:

The code that is cousing this error is:

I am writing a program for my A-level coursework But for some reason I got this build error this has never occurred to me before, I have no idea why I can't use string for the name of my form.
When I add a new, empty form to my VB.NET VS9 project, the linenherits System.Windows.Forms.Formis missing.What am I doing wrong here?I thought it would be added automatically.I experienced that some thing get weird if this line is not there (Form_Load is not firing, I think).
I've almost finished a binary clock, but I have one problem. The user should choose between two different backgrounds, named binary.jpg and binary 1600.jpg
Dim Bild1 As New Bitmap(Application.StartupPath & "/Bilder/binary1600.jpg") Picturebox1.Image=Bild1
i have this code but it doesnt save in Application.StartupPath :
Public Class Form1 Private Property voice As SpVoice Private Declare Function mciSendString Lib "winmm.dll" Alias "mciSendStringA" (ByVal lpstyCommand As String, ByVal lpstrReturnString As String, ByVal uReturnLength As Integer, ByVal hwndCallback As Integer) As Integer
I have a FolderBrowserDialog and I want to set the root folder to the folder that the application is sitting in.I do not know in advance where the user has put the application, but I can find that (I think) by using Application.StartUpPathHow do I set the FolderBrowserDialog.RootFolder to the Application.StartUpPath ??
Having finishedd an app, I'm having problems with Application.StartupPath in sql lines. I've tried commas, () and lots of different things. here's the code. This works, of course:
been banging my head on this, i need to get the applications path, then go up 1 folder then into another. As i have a main app and sub apps.
So were Application.StartupPath()is for example:"C: Main app folderSub app folder"How do i then go up a folder to"C: Main app folder"I Know it needs some string removal using on it but i can seem to get it right, after which i could then use Application.StartupPath() 'string removal here" & " ools"to navigate to another sub apps folder etc.
