Incorporate INI Files For Profiles In Order To Quickly Pull Up Data From One Person To The Next?
Nov 1, 2011
I am attempting to create a basic program and I need to know how to incorporate INI files for profiles in order to quickly pull up data from one person to the next.
Public Class IniFile
' API functions
Private Declare Ansi Function GetPrivateProfileString _
Lib "kernel32.dll" Alias "GetPrivateProfileStringA" _
[code]....
And placed it into a module, which I then wen't to my main program and attempted to place this:
Dim ini As New IniFile(Profiles.ini)
Dim value As String = ini.GetString("Names", "1", "Default Value")
To attempt to retrieve the data, but I get no error or information from it. The ini file is inside the folder of the project and I set the SectionName and KeyValue to the corresponding names. I think I am having trouble with syntax? Not 100% sure. This is the code that I got from the same source as the module for using the module.
Dim ini As New IniFile(FileName)
Dim value As String = ini.GetString("SectionName", "KeyName", "Default Value")
And I adjusted to what I believed would be the proper format.
I am trying to work with an access database. If this line pulls data from a dataset and puts it into a textbox: TextBox1.Text = Me.A_DataSet.a_Table.Rows(0).Item(0).ToString How would I pull the field name? For Example, in this database I have 3 fields:
I have a SQL database that is different than the one in ASP.net so I had to create a custom membership Provider. The provider to get the user looks like this:My SQL class name is CustomSqlProvider:
Public Overrides Function GetUser(ByVal username As String, _ ByVal userIsOnline As Boolean) As MembershipUser 'Dim connectionString As String = "Server=***;Database=***;User Id=***password=****"'
[code]....
After adding those gets and sets and assigning parameter variables to my Sproc parameters I get the following error: "Reference not set to an instance of an object." at this line of code:
Dim currentUser As MembershipUser = Membership.GetUser() Dim UserId As Guid = CType(currentUser.ProviderUserKey, Guid)
And this is what I have on the UserInfo.aspx.vb Page under the Button click:
Dim sql As New SqlClient.SqlCommand("Update_User", con) sql.Parameters.Add("@UserId", SqlDbType.UniqueIdentifier).Value = UserId sql.Parameters.Add("@UserName", SqlDbType.NVarChar).Value = txtUserName.Text
I am working on a application that stores videos, images and files. I would like to give the user the possibility to encrypt them. I am tying to use AES to encrypt them but the problem is that the decryption takes to long.I was hoping that the loading time from the hard disk of the encrypted file was far longer than the process of decryption of an image for example but i was wrong
So if i try to 1) load the image 2)decrypt it and 3)load it in a image control it takes 15 times more time that loading the original file not encrypted
I want to create my special full-text index using text files, without database.I saved records ids for every word in index, in text file..Now if I want to search for tow words together; I have to get ids that is shared between these words by comparing text files of these words ids; and saving the result in other text file.[code]But now the problem if the first word has 100,000 ids and also the second word same it; the loop will take too long time! It will loop 100,000 * 100,000 times!How can I find another way to compare these files quickly; or another idea for my full-text index with text files?
How do I incorporate my custom ASP.NET/VB.NET stuff into a DNN site? Long Version: I'm learning about DotNetNuke. I haven't done much yet, but I'm spending a while analyzing the software, hoping to be able to use it for a very large upcoming project.
I have 202 .html files and at the beginning of each file, I need to add a chunk of php code. I could make this myself, but to be honest, it would take me forever and I might as well just manually edit them lol. All the .html files are in one folder.[code] one other thing that would be VERY cool, is if it could add the files that are not edited to a listbox or an outputted text file.
I have a Person class, which contains two public properties. I am trying to add items to it as follows.
Code:
Class frMain Dim persons As New List(Of Person()) Private Sub frmMain_Loaded(sender As System.Object, e As System.Windows.RoutedEventArgs) Handles MyBase.Loaded GetInfo()
[code]....
When I try to use the Object Initializer, I get an error Error"Value of type 'Person' cannot be converted to '1-dimensional array of Person'.
I'm trying to make a application that allows the person to script config files for an open game server project so they don't have to do it manually... I'm starting with 3 groups. Those groups are "NPC NAMES", "MONSTER NAMES", and "MONSTER WALK POSITIONS"... I want the user to be able to add as many items to the group as they want... Right now I'm using a listbox, but its very messy... I want the user to be able to add items to these groups, and then add the items of each group to a .txt file.
i am working on the MSDN tutorials through virtual labs and am encountering a problem with the very first tutorial regarding consoles. I am required to create two notepad files: Module HelloWorld & Public Class Person which I have done without errors having triple checked them. When the files are created I compile the HelloWorld.vb file and a .exe is created
I follow the rest of the steps and encounter an error when i try to compile the Person.vb file using the line vbc Person.vb/t:library/out:HelloWorldLib.dll as i am getting the following errors:
vbc : Command line error BC2001 : file 'HelloWorld.vb/t:library/out:HelloWorldLib.dll' could not be found vbc : Command line error BC2008 : no input sources specified

I have a databound Datagridview. The DGV is bound to a datatable of a strongly typed DataSet created using the wizard. Is there any way to re order the columns before displaying them eg: the Columns are displayed in the DGV in this other Col4, Col6, Col3, Col1,Col5, Col2
But I want to it to show as Col1, Col2, col3, Col4, Col5, Col6?
I realise that the display order followed the Column order in the database table and by extension, the datatable. I have re-arranged the columns in the Database but the Datatable still retains the old order.
I have a form that searches the computer for a particular .xml file that will have the same name in different folder dates. Set in this format[code]...
I am trying to learn the new methods in .net, but, I cant see a way to step through the data like you can in an ado recordset. I want to pull data from a table once, then split the data with a filter, then step through the rows gathering the dtata till eof. Clear the filter and reset it for the next batch.
I want to make a program that looks like an address book (name, birth date, phone, e-mail etc) and stores all the persons data in a txt file. If I add a new person, for example, it will be added after the last person that was added in that txt file.

I have two comboboxes and a listBox to display data from several databases. The whole process should be that after an option is selected in the first comboBox, the second comboBox and the listBox are populated. So for example, I could select a Company from the first comboBox, and the second conboBox will be populated with all it's locations while the listBox will first display the location of the headquarters(default location). But the user can then select a different location from the second comboBox if they want to and the listBox will then display the location of that newly selected office location.how do I dynamically pull these data from various databases cause all the companies will have their information in separate DB's. My challenge is how to dynamically pull these data from the various DB's to populate these 3 controls.
My program pulls a weeks worth of records at a time and filters it into daily columns on a form, the problem is that there are ~80 fields to be filled in this manner and as far as i know each one has to be check for null before it can be filled. Could someone tell me if there is a faster way to do this? Below is my current code for one set of fields.
Private Sub cboDigit_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboDigit.SelectedIndexChanged, cboOffice.SelectedIndexChanged, dtEndDate.ValueChanged, dtStartDate.ValueChanged

I'm having a problem to pull data from MS Access to my combobox. I know how to search one data using another data (e.g: using IC num to search name) but this time I just want to pull the data (e.g: name) that has several rows to my combobox. I think the method is the same but don't know where to change it.
Then when I added new names to the combobox, want to save it to my database, can each name be saved in different rows? I added the names to the combobox 1st, after that then I saved it. [code]...
I am working on a VB.Net project and trying to get it to pull data from a database. I have the data base located in my bin folder with in the project but I do not know the exact path how to do it. The code that I am using is noted below
