In our projects we use setting variables to store user setting for the applications. Moreover, with every latest version of the applications, we upgrade these variables to retain user settings.Normally, this works fine, but recently one of my end user reported an error i.e.Configuration System failed to initialize". The error is related to user.config file. Therefore we requested the user to send us his file.After received the folder, we noticed that it contains 3 files (3begfjb.newcfg,3begfjb.tmp and user. config). 3begfjb.tmp is an empty file, while 3begfjb.newcfg and user.config are identical files. We tried to open these files but the data in user.config isn't proper xml rather its unreadable formatted file.Do any you guys had experienced this sort of issue or any ideas how and what may have created these files and corrupted user.config file.
View 3 RepliesI have a ASP.NET 2.0 website created in C# that acts as a completely independent site and I am looking to integrate this into an existing ASP.NET 2.0 website created in VB.NET. Unfortunately I just don't know much about the server management side of ASP.NET yet so too much I'm unaware of when it comes to IIS configuration etc. Does anyone have any advice as to how I can go about integrating this? Basically I want to host it in a subdirectory from root so when you hit example.com/myindependantsite/ it will pull up my C# site.
One possible solution I came across mentioned just dropping the project folder into the root directory and setting up that directory as an application virtual directory in IIS? A few other random questions were small things like would my application relative links (~/for-example.aspx) stay relative to my root subdirectory if it's made into an application virtual directory? Just trying to get this running on their site but like I said it's completely independent so want to preserve my websites environment.
I want to create a program to fetch information from a website (that's fine). However, you need to be logged in to get this information. I just want two simple textbox controls that I would type my username and password into and hit submit and the information would be returned to me so I can use it. (I don't want to use a webbrowser control)
View 2 RepliesI want to fill a dropdown in the pageload by using a BLL and DAL class. This is the code
Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
dropBrand.DataSource = BLLManufacturer.selectManufacturers()

The first dropdown fills up with brands as it is supposed to do, but the second does not. The second dropdown needs to show car models by the chosen brand in the first dropdown. However the dropBrand.SelectedValue always returns 0 whatever brand I select. Without the convert toint16 it doesnt work either nor with convert toint32 or toint64.
I am limited for space on my form. Is there a way that I can have a textbox act like a dropdown? So the form will show as one line. If the user starts typing multiple lines then it opens the drop down so they can see what they have typed. Will it have all of the same goods as a textbox, like copy and past? When they are not typing then it will be closed and only showing the first line.
View 3 RepliesI have been to internet hail and back trying to figure out what Im doing wrong with my combobox cells and columns.When I add items to the cell using .item.add("something"), othing shows in the cell. I can add 5 items and nothing shows up. No dropdown and nothing in the cell. In debug, I can stop and look at the cells value and see that n-items where indeed added but yet, they dont show up on the screen in the DGV.I have a DGV and I have tried this 2 ways.. creating the columns in the form designer and by adding the columns in code.Heres a snippit of the datagridviewcomboboxcolumn (thats a lot of typing) anyway.. this is the def for it and the surrounding columns:
Dim conx_text_col As New DataGridViewTextBoxColumn
conx_text_col.DefaultCellStyle.BackColor = Color.Teal

I have a large VB/SQL application that I have created a problem in. I have a table of procedures that have an active flag on them. This flag can be toggled through a user screen. Other screens access this same table to populate dropdowns. The values are stored in the table as the ID field (PK). The problem I have is that I am selecting the dropdown values based on the Active flag. If I select a record that has a procedure stored in it that has been made inactive, I get the old Object Not Set to an Instance.... error.
What I want to be able to do is check for the value in the record when populating the dropdown and allow the record to be displayed by bypassing the SQL error and just showing the dropdown value as blank while not altering the record itself. I hope I'm making sense. Code is below.but I'm back in app programming after being a SysAdmin for 20 years and I'm still rusty.[code...]
How can i make a dropdown list with checkboxes ? I have a windows app ( vb.net) and the checkboxlist control is not real an option with the available space on my form.
View 5 RepliesUrgh, I have spent the last couple of hours on this now. I normally end up finding the answer from a bit of Googling, but not with this one. Bit of a headache.
My questions:How can I catch when a user clicks the dropdown arrow on a combobox and prevent the dropdown list from being displayed.How can I then clear and populate the dropdown list and display it programmatically?
I have one agent program remotely connected to a server over the internet. When you click the dropdown arrow on the agent, it queries the server to determine what needs to be in the dropdown list. It then displays the dropdown list. The comboboxes act as filters for the subsequent comboboxes on the GUI. A delay in displaying the dropdown list is perfectly acceptable while retrieving the data. Initially querying all the possibly entries in the dropdown list is not an option because there are so many! Needs to be comboboxes compared to listboxes as the user may also type an entry that is not in the list.

Is there a way to add to the "Show Output From" dropdown list. I've been going in circles on MSDN looking at Listeners, Writers, Trace, Debug, ConsoleTraceListeners etc. with no luck. I really would like my own pane for debug output because I don't want to disable any of the messages in the debug pane, and a lot of stuff gets pumped out there.
I found a way to add a new pane to the output tab through a macro/addin but don't know how, or if, it can be written to through code.
Short of that I'm really just looking for a better/more intuitive way do display debug output. Colored would be nice. I've tried very unsuccessfully to use nLog - but the configuration/documentation left me scratching my head.
Is the output window really what most people settle for?

I'm trying to make a user control similar to the Windows Vista/7 breadcrumb bar used in windows explorer. However, when I show the drop down menu for a breadcrumb with many sub items, I get a very long list that sometimes exceeds the screen size. In the Windows Vista/7 example however, there are a maximum of 18 items displayed at a time and a scrollbar appears at the right when the number of sub items exceeds this number (18).

So in winforms, every dropdown combobox has this little arrow thingy to the right that tells the user it's a dropdown, kinda like this:Now how do I figure out how wide that is in pixels? Reason is, I'm using ControlDrawToBitmap, this doesn't draw the text properly for the combo boxes, and I can redraw the contents, I just whack some of the arrows (which are drawn properly).

View 1 RepliesI am using VB.net 2005. I have a DataGridView with several columns. One of the columns is a ComboBox. What I want to happen is when I populate the DataGridView by binding it with the DataTable I want the ComboBox item that is in the DataTable field to be the one that is shown as selected in the drop down. Then if the user wants to change the value they select a different one from the DropDown (and I will perform some update action). My code displays the correct DataTable item in the ComboBox, but the ComboBox will not drop down so a different item can be selected.
This is the code where I set up the ComboBox in the Form_Load and add all the possible items that can be in the DataTable Destination field.
c10 = New DataGridViewComboBoxColumn
c10.Name = "Destination"
c10.DataPropertyName = "Destination"
c10.MaxDropDownItems = 5
c10.Items.Add(" ")
