I have created a procedure as below for ressting colors of any control I decide
Private Sub ResetColors(ByVal Control As Control)
Control.BackColor = SystemColors.Control
End Sub
But the compiler cant accept (Tooltip1) I think because it is not a control Call ResetColors(ToolTip1)<---- Error
I am using a monthcalendar control in my application to allow a user to select a day from the calendar that will load data for that day. the background is totally white (ugh). there is a backcolor property, but when i set it to say Cyan (yea right), the calendar still displays as white. I also can not set Forecolor, TitleBack/Fore color either.
I have gone to my project properties and turned off the "enable xp visual styles", and that had no effect. turned it back on...cant tell a difference. i am currently on windows 7 running VS2008 Team Edition. It would be really nice to change the look of this control to match the styling of my application.
I want to set a color on items and subitems being displayed within the listview control in a detailed view.Using the forecolor property setting would change the color of all the contents in the listview control. All I want is to display different colors on each column of the listview control. If I have four colums on the listview, it should display the contents on each column in a different color. I tried to do it on my own but it was unsuccessful. I'm looking for the exact code to set the color successfully. Currently, the code below is what I have to display the data on the listview. What line of code should I add on the code below to set different colors on items and subitems of the listview?

I am trying to use a background image for one of my programs and I get this error when I try to make the BackColor Transparent. It allows me to use the Background image I want but I get this error when I try to change the BackColor to Transparent. A Box pops up that says "Property value is not valid.", then when I click Details, it says "Control does not support transparent background colors."

View 3 RepliesMy main form is a tabbed control with 2 tabs. The first tab is has two listview controls which display information about the current machine. The second tab contains a treeview control and two listview controls. This tab recreates the device manager in windows. I created a Machine class to gather the information about the machine that I want to display to the user. When I call the Display() Method from my form's load event everything appears to be fine the first tab's information is displayed in the listview controls.
Here's the kicker, when I click to the device manager tab there's nothing there. The LoadTree() procedure never fires. This code works, I've seen my device tree display a thousand times in the past. When I comment out the call to Machine.Display() my device tree reappears no problem. The code compiles fine no errors. I know the problem has to be in my Machine class but I have no idea what could cause this kind of response. I've never seen a program compile clean and then refuse to fire a procedure call but not produce some kind of runtime error.
I am trying to make a routine that will be called everytime the mouse button is clicked. I want it to be called so that the controls event that the mouse is clicked on is triggered.
For example:
You have a button control on your form. Instead of having the Button1_click event
You have a Control_click event. And that Control_Click event will be used for each control on the form.
I've got the following set up:On a webapp, I've got an updatepanel Inside this update panel, I've got two regular panels and a set of two radio buttons, radio1 and radio2.On Panel1, I've got 4 drop down lists (lets call it DDL group1), being loaded by the CascadingDropDown Extender, meaning the first box triggers the second, and so on. All 4 DDLs have autopostback enabled, meaning that every time I select a value, a SelectedIndexChanged method is called which loads data from a database, based on the information selected on the last DDL.
On Panel2, I've got the same set up, except that I've only got 2 DDLs (let's call it DLL group 2), also linked as cascading dropdowns. These also have SelectedIndexChanged methods.

I've created an application that runs queries against a SQL server (via Data Adaptors) in VB.NET 08 and returns the results to a DataGridView. It works great and returns my data, but when I switch to a different query that returns different columns, the DataGridView keeps the old columns from the previous query and adds the new columns from the new query to the end (far right) of the DataGridView. Is there a way to counter this? I don't want those previous unused columns showing up in my results. I tried setting the DataGridView DataSource and DataMember to Nothing and that didn't fix it.
View 3 RepliesI have a DataGridView in which their is one column defined as a CheckBox. This checkbox is used to delete the record if the user chooses to do so. When they check the box, the user is prompted with a confirmation deletion message. My issue is that if the user chooses not to delete the record, I want to "Uncheck" the box and I can't get this to work. I've tried using the below code and it still won't work.
dgvBuild.Rows(e.RowIndex).Cells(6).Value = False
dgvBuild.Rows(e.RowIndex).Cells(6).Value = CheckState.Unchecked

View 4 RepliesLooking to make a simple VB form, that has three text boxs on it. One for a users username, and two for passwords. What I want to do is provide teachers with this form, they type in a students username, and if that username is found in AD it enables the two password boxs. Then the teacher can type a new password for that user in the boxes (the second one obviously being a validation) and then when they click save, it updates the AD account with the new password. Any ideas on how to do this? Does anyone have any code?

View 1 RepliesUsually, when I reset the IIS of a remote server, I have to use "Remote Desktop Connection", log in, and go to DOS , and type "iisreset". Now I'm wondering is it possible to do the exact same thing without using "Remote Desktop Connection" application? Could this be done programmitically and remotely (because the program will not be running on the actual server)? Of course, I'll be providing the username and password within the program.
View 2 RepliesI have a form with lots of labels on it, and a reset button to reset them to a default text. This reset sub has lots of lines of code to get this done, but I think it cen be done in just a few. I thought of something like:
For Each Label In Me.Controls
Text = "0"
Next
but this doesn't work, or anything else that I've tried. how to do get this done? And what if I want half of the labels set to 0 and the other half to 1? Would that be possible without setting them all seperately?

I'm storing data using my.settings (e.g., to use as a incremental counter). When I run my application it increments the value but, I do not know where to reset this value despite looking at all of the project files for them.
Is there a file that contains this data?
Note: at times during testing I don't want to reset the value(s) back to zero.
I'm trying to do a simple loop while reading a file. I have tried to make the streamreader as a public value, so this way it would be passed between the subs, or rather changed by each sub working with it. The problems comes into play, when I double click the read button, since the value of sr is assigned to -1 after the first full read, so the program doesn't read the data from begging but assumes the end of the file and stops. Is there any way to reassign or reset the value of sr so that the file will be read again from the beginning? This is the example code I got.
Public Class formcollegetut
Public sr As IO.StreamReader = IO.File.OpenText("colleges.txt")
Private Sub btnDisplay_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDisplay.Click
Dim test As String = ""
Do While sr.Peek <> -1

I'm using the font dialog and have noticed that when I select/highlight portions of text and then cancel out of the dialog, the selected text is changed to the default settings (i.e., font type, style, size, color, etc).

I have a web site which uses cookies using ASP.NET, however everytime I publish a new site and upload all or some of the new .dlls it invalidates all the existing cookies. The cookies are used to track simple logins, but I want to maintain the cookies that were created before a publish so they are still usable afterwards - this seems to affect webkit based browsers and in my testing I can replicate this issue after each partial or full publish.

Long story short I have a situation where some users have access to two domains that do not trust each other. They log into one domain and their user ID's are identical on the other domain. So when they change their password on the first domain they need to call into tech support to have it reset on the second domain. I'm writing a app that checks if they have access to the first domain but not the second and if this is found to be true it prompts them for the new password to update the second domain.
Here is where I am stuck. The following code works GREAT but I need it to be more flexible:
Code:
Friend Function ResetPassword(ByVal OldPassword As String, ByVal NewPassword As String, ByVal UserName As String) As String
' Resets a users domain password
[Code]....
The issue is the CN is different between domains (one is first name last, other is last name first) so I need to search by UserID which is the same between the two. So I tried searching by sAMAccountName but it says object not found. Also I need to be able to search the entire Super Corp OU. When I get rid of the extra OU's the search also fails
So I need to search LDAP for sAMAccountName anywhere in OU=Super Corp. How can I do this? Every combination I try seems to fail yet if I hard code it like the above example it works great. The idea is to replace CN=John Q. Public with sAMAccountName=" & username & " to pull jsut that user on the fly.
If it matters all clients are XP SP2 or higher, both domains are Server 2003 or higher. VB 2008 SP1. The error message when a different search is done is a "Object not found".
after the backround image property of a form was set by the main code how can the user reset the form's backround image to none (the plain grey color)?

My deployment of upgrades to an application written in C# (.NET 3.0) consist of simply replacing an older .exe with the new one. Because that older version can currently be used by some customers, I simply rename the old version to blahblah.exe.old and copy the new one to the same folder. When the user opens up the application again, the new one loads up.
The problem is, every time I deploy a new version, the user scope settings are always reverted back to the default values.
I use VS 2008 Standard. If I do a QuickOnce deployment after resetting Application Files in the Publish Tab I get a bunch of messages saying that various files are not in the GAC. To solve this I change the Publish Status from Prerequisite (Auto) to Include and set Download Group to Required. Then when I install the application I get the splash screen and then the message that the application has stopped working. There was a workaround posted to delete /bin/obj/.cache etc, but I have no /bin/obj/ folder.
View 1 Repliesive added a special color for some items into a listview, that was the only reason i picked up a listview over a listbox btw, anyways when i sort the items into that listview the items backcolor simply does not exist anymore, is there anyway i can still sort the items out and avoid this problem?
The only way i know right now is to add loops and numbers as reference and then setting those numbers as colors reference, then erasing them and add the backcolor, this is not viable to performance at all
