I have constructed a user control and I would like to be able to save a simple option (very little data) that can be loaded/saved.There could be more than one of these on a form.And if I were to write a small program for my wife, I wouldn't be sure what directory to use to store the data

View 4 RepliesI am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I am trying to create a wpf program that allows the user to create custom shapes or pick premade shapes and that after making their selection, a canvas shows their shapes randomly sized, positioned, colored and copied in multiples. I am hoping that on click, the program will put its output on a time interval and that the user can click stop when they are satisfied with how everything looks. My issue is, I would like to also give the user an option to save their created artwork as a jpeg file. Also if I wanted to link this file to a web browser what will I have to do?

I am creating a windows application using visual studio. I want somehow to insert an excel file into the application so the user will be able to download it from the program and save it to his computer. This means that the file will be a part of the program. There will be a button that will prompt the user to save the particular file somewhere so he can then view it.
What should I do in order to "embody" the excel file to the application? And what code should I write to link the file with the button?
I need to store specific information about a user in a file of some sort. Something like an old ini file?

All things point to a database but for several reasons I can't use a database.
My program requires the reading and writing to a file that is shared among all users of a system. Currently I keep this file (an XML configuration file) in the directory that my application is installed to, which is C:Program FilesSomething by default. On Windows 7 (and probably XP too, but I haven't checked), regular users cannot write to this file. While I could probably set permissions as needed in my installation program, I'd rather find a more appropriate place for this file.All users need to read and write to it. Doing some Googling turns up C:ProgramData for Windows 7, but XP doesn't create this folder. Is there a common place on both platforms? Finally, is there an environment variable I can query for it?
View 2 RepliesI'm trying to create an app to launch at start up that will ask you what applications you want launching, or if you want all your favorite app's to start up etc. But before I go any further, I think its crucial to know how to save settings that a user has entered (such as program location and name in this case) so that he/she doesn't have to enter them every time at start up.
So far I have just made this, can anyone tell me how I would get it to save the settings entered?

Option Explicit On

I just want to know what is your suggestion about storing database connection strings in .NET? I am using My.Setting usually, but now I am facing with versioning of my application. When I upgrade my application to higher version the value in My.Setting has been changed, it didn't remain as user has set before, but changed base on my machine's setting. eg. the value in My.Settings Version 1.0.0.0 (User's computer) is 'ABC' When I develop again some new feature on my machine and set its version to 1.0.0.2, of course the connection string in my computer's My.Setting file is different with User's computer's My.Setting. So when I copied my recent updated file to use's computer, then run the application, the application read the new My.Setting file from my computer but not from their computer. the value in My.Settings Version 1.0.0.2 (Developer's computer) is 'DEF' Therefore I have to reset and reset their connection strings onve I updated their application, that's too annoying?

I am working on a VB.net winform application which makes extensive us of a mssql database. For the most part (almost exclusively), I have used the Visual Studio dataset for accessing the data. This means that the connection string was created as a program setting, and is saved in the app.config file. The problem that I have, is that I need to move this connection string to the system registry because it has been deemed by the powers that be that a config file is not secure enough.
I think that I can figure out how to access a registry key, and I know that I can save the string to a registry key, but the problem that I am running into is that I don't access the connection key in the code anywhere to easily swap out the registry key for the existing program setting. When VS creates the connection and dataset, where is the connection string referenced? Is there a simple way to swap these out? is it possible even to just reference the registry key in the setting so that I don't have to find where the setting is used and switch it out?
I have a user control in the toolbox and can now put it on a form in a project.However, I play a .wav file in the control and it is referred to in code by the filepath and name.But I want to "embed" it in the control so that it isn't dependent on the path.As far as I know, I embedded the resource, but I don't know how to refer to it to get it to play with My.

I am currently creating a tool that can manage local user accounts on Windows-PCs. I am using the functions described on
this MSDN page ; and after some struggling, I got most of them to work.
Unluckily, I haven't found a way to set the option "User must change password at next logon" while creating a new user account. I use the
NetUserAdd -Function to create the new user. I set the level to 1 and supply a
USER_INFO_1 -Structure . This structure accepts flags, and the flag UF_PASSWORD_EXPIRED seems to be exactly what I want - but when I set it, the user can log on without changing the password first...
I'm developing on Windows 7 Ultimate 64-Bit using Visual Studio 2010 Express.
Here's my code:
#Region "Constants"
Public Const UF_PASSWORD_EXPIRED As Integer = &H800000
Public Const USER_PRIV_USER As Integer = 1

View 1 RepliesCurrently, I am try to get the email addresses that have been saved or stored by the user of the computer. This isn't the emails that the user has sent or received, or the contacts he/she has in his address book. Just simply the email accounts that have been accessed from the computer.I know that there are some locations stored in the registry that have the email account. The email addresses that are used on the current computer. I just can't seem to find them on my computer.I am not sure if the registry is the only place to find it or if it stored on the web browser such as internet explorer or google chrome.
View 1 RepliesI am writing an application that connects to a specific com port. This com port can change depending on how many physical ports are on the PC, and if other USB devices have installed com ports before this one.
I have the communication to the com port all working great, but I need to get the com port description not just the "COM#" which is all I currently get.
I found in the registry where the description is stored but am having trouble doing what I need.
In this key:
Code:
HKEY_LOCAL_MACHINESYSTEMControlSet001ControlClass{4D36E978-E325-11CE-BFC1-08002BE10318}
there is a varied number of sub keys. The are numbered 0000-NNNN depending on how many ports you have. Inside each of these keys, there are multiple values, although I am only interested in one or 2 of them.
My problem is, that I do not know how to get a list of the subkeys (the 0000-NNNN keys/folders) from the original key I posted. I have looked through a few registry tutorials, and I can view the default value in the listed key, but I could not find how to list the subkeys of the listed key.
Does anyone have any sample code they could share that shows how I can get a listing of subkeys, and then run through those subkeys checking for a specific value in one of the strings contained in the subkey?

View 2 RepliesI have an aspx page that has two different user controls. I want to find user control A and be able to set properties, etc., from user control B.
I was thinking I could do something like this:
Dim CMFilters As Control = Me.Parent.FindControl("CMFilters")
...but that doesnt work to be able to set properties and call methods. I somehow need to get the user control and and declare it as that user control type.
I made a custom progressbar as a user control. And I have only been working with forms 'n classes. As you all know, when you create a component in class, it gives you the dll file for the custom component or whatever you made so you can use it on any program. On my custom progressbar, I don't know how to get the ocx or dll file so I can use it on my other programs. OR.. if this is even possible lol. If you could help me on this, that'd be great. And I don't know how to make a custom progressbar out of a class, only user control, so if you could teach me how to make a progressbar out of a class, then that'd be awesome too.
