Create A Multi Client Scheduler Using Visual Basic That Save Data In Xml (as A Database)?
Jun 13, 2010
I am a student and trying to start a programming career, my colleague asked me to make a multi tier or multi client desktop application for the schedule tracking using xml as a database; however the desktop application would be deployed in one or more computers but my leader can monitor the info from her office in addition she wanted me to put administrative privilege to avoid unauthorized access in some database features of the system. an info regarding multi-client desktop app.
However I have hit a massive brick wall with my program. My program that I'm trying (can't emphasis this word the importance of that word) to create a Client/Server chatroom using TCPClient in Visual Basic. So far I can get my client to speak to my server. However, i'm trying to get the returned data to display in a listbox which never happened, i then tried a label, which again never happened then a text box which I'm sure you can figure out how that went! I'm not great at networking programmers nor am I not bad I'm terrible but duty calls when it comes to projects.
The code I currently have was mostly taken from the net but when I have the program fully work and I understand how the software works I intend to heavily modify for it to suit the needs of what I need to achieve. where I can get my client to display the data from the server that I have already sent to the server (which displays successfully within the server).
I was wondering what is the easiest way to save and load data through different forms in vb. I just want to save 3 textbox.text that a user saves and be able to load it o
I'm a college student and starting to use Visua Basic 2008.Unfortunately couldn't find the right algo for adding a database in vb 08. T_TMy problem is that how to add a database access 2007 in visual basic 2008.
For example, i installed the windows application in more than one pc. All the pc's are in network. I want to save the data in a single database. How it is possible?
I was wondering how to get a certain data from a MS database and display in a label. Example(Database entries)
[Code]....
The name will be displayed in the label depending on the year and number typed in two text boxes. So if typed 2009 and 1001, the label should display name2. I don't have any background on SQL. The only thing I did for now is that I added the database in the data sources and added a TableAdapter.
I am trying to Save my data into Local Database (*.SDF or *.MDF) but i due to some reasons i can not do it. I have seen 100s of Video on it and tried all possiable ways, but still my data is not saving into Local Database. and i do not get any error messages. However i can save my data into SQLEXPRESS database. i am using Visual Stodio 2008.
i can connect to only one Data Base with dataset in Visual Basic . but i want Have Dynamic connection to data base i mean in want to my appliction users have ablity to connect to any data base they want (For Example : Choose file from menu and then open and then Select any Data base.)
I have a database called "IMYS" and a "Customers" table in it. What I want to do is: Define a variable like "Last_Name" and retrieve last names of customers one by one. I've tried this before (and, it doesn't work for me):
=== Dim Last_Name as String Dim I, K as Integer Dim CustomersTable = New IMYSDataSetTableAdapters.CustomersTableAdapter
create admin form to register, Remove, Edit user accounts in the system connected to Microsoft SQL Server R2 2008 or access database ? any toturial videos or instructuions step by step ?
I've small project to do and now I'm stuck in middle. The program is to read the sequential text file and load it into a array/array of structure.The data information is like this (sample):
ID | Name | Type 1 | Cat | Animal 2 | Dog | Animal
[code]....
This is Just as sample data, my original data is more than this.I've open the DATA.txt file using FileStreamReader:
Dim FileStreamReader As StreamReader = New StreamREader(DATA.txt)
Read all the elements in the list and pass through ReadArrayString.Split the string using:
Where index 0 is the ID, index 1 is the name, and index 2 is the Type Then I load the types in the dropdown combobox menu from the array with out duplication. Like this:
If TypeComboBox.FindString(ReadArrayString(2)) < 0 Then TypeComboBox.Items.Add(ReadArrayString(2)) End If
Now When you click TypeComboBox it will show drop down menu with following list only.
Animal Bird Fish
After this, when Animal type is selected/clicked from combobox dropdown menu then it should only add the Id and Name of Animal type in the ListBox.Pseudocode may looks like this:
If Animal is selected/clicked from TypeComboBox then Add Cat into listbox Add Dog into listbox
[code]....
I've only figure out load items from only one column/array into combobox with out duplication.But can't figure out to compare the value of one column/array with another column/array and load it into listbox. I don't want to hardcode or write matching value inside the code. What I want is use the Array.
I would like to ask how to connect our application to connected computers in a LAN.Will I use the winsock control?How can I run queries using a server database?Any answers are welcome.
I need some clarification. I'm planning to make a Scheduler program where it will fetch data from a MS Access Database, and I also want it to upload the data to a web server (MySQL Database) in JSON Format.
In the first process which is the fetching, I'll use System.Data.Ole.db namespace. This namespace mostly worked in MS Access. In the 2nd process which is the uploading, I am planning to use FTP protocol and should be JSON Format.
I was just confused with the second step, is FTP protocol applicable for this process?
I will make an Android apps to view all the data that will be saved on the web server.
I am making a server - multiple client windows form application using Visual Basic Express 2005.
I was wondering if there was a way that I could debug multiple instances of the client at the same time?Ashray Lavsi If my post answers your Question, don't forget to "Mark it as Answer"
when the user clicks on the add button another form launches, which enables the user to add student info such as name, address, course, start date and end date, this information is then written to class when the ok button on that form is clicked, and then displays the data on the initial form in data grid. the user can add multiple entries and they are all displayed on the intial form and a the data grid is populatedwhen any of the rows in the displayed grid is selected, and the update button is clicked then the same form launches as the previous one and but this time its in the update mode and pre populates the form with the inital values.
I'm trying to load the data by using the first column as the object name and the second as the value. I've had some success with the following (skipping some basic IO lines):
trying to save the settings in a settings form but every time m setting the settings (when the form is running) then exiting it and then reopening itare the settings that i setted not there Ex : I open form2 by clicking on a button thought form1 and change the settings for example i uncheck a checkbox then do i close form2 and then open it again. And the settings should be saved so the unchecked checkbox should still be unchecked.BUT when i close form1 should the settings be unsaved and go back to normal :)
I have yet another Problem with the save button on my form. After filling out all the textbox's, Selecting the date from dateTimePicker Selecting comboBox's Items I get an Error message saying: "Column 'JobID' does not allow nulls". "(I thought this ID column Inserted a number automatically").
I need to encrypt some basic data being sent from server to client.
I was going to open a file in bytes, convert it to chrs (Modify odd numbers by adding 2 and even numbers by adding 3) then use Base 32 (Triacontakaidecimal) or Base 16 (although base 16 will occupy twice the space). Convert the data back to bytes and after do the same with the decryptor.
About using base 32, is there some sort of class in vb.net or maybe an api?

I'm trying to save a setting that keeps what background image I'm currently using.If it's an external file, there is no problem, i can just get the .location and set it in a String setting to store it.
But, if I want to store an image resource as a setting, how do i do it?I know i can store rawdata, like bitmap information, but then i can't set that type of data to the my.background.
I don't know if the question should be: "how do i reference resources", but the my.resources.resource.methodsList doesnt contain anything that seems to be of use.
I am working on an virtual operating system. And I want the user to be able to change background, and at the same time save it! So, the next time he opens the application, the background is saved and changed.
I know that I have do this through project > settings, but I don't know how to program it. I have managed to allow the user to change background, but dont how to save it. Could anyone solve this little problem for me?
