My program requires that a picturebox change its image during run time. I've used:
PictureBox1.ImageLocation = [file location]
PictureBox1.Image = Image.FileFrom([file location])
Both work fine, usually.
[code].....
I set a background image to my project. When I run it, It comes with an error, file not found:
Could not load file or assembly 'System.Drawing, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified.. I do have the file, and I didnt move places. I still have it and also reloaded it in the resources.
I have a window application develpoed in vs 2008, framework 3.5, in which i have put a button.. Now where i click that button the other text boxes are filled up with the data from database thru web service.. what i want is while all text boxes are being filled i want to show an animated loading gif image till data loading is completed in all the text boxes.. i have tried to use image picture box but while data is loading gif image is displyes but in static mode.. cant see animation... i think this is because data loading and animation both are done thru one UI thread..
View 8 Repliesi have a problem in loading an image from a file in vb.net. I have the following code in the class of my project.
Imports System.Drawing
Imports System.Drawing.Drawing2D
Imports System.Windows.Forms
[code]....
So, now I've exactly used this code to load an image from a path specified. Still, i seem to get a blank form when i run. im quite sure about the path and the existence of the file. Also, the exact piece of code is also available at: Draw an image : Draw Image2D GraphicsVB.Net Tutorial So, now do i have to insert a picture box to se the loaded image. Its like.. ive used the graphics thing to draw the image. so i reckoned that picture box was unnecessary.
I currently have 4 images that I need to load into a picture box at different times, it works fine for me but if I send it to a friend it wont work because the file path is different. I use this at the moment:
If filmType = "Jumper" Then
img = "E:TheatreBookinginimages"
picFilms.Load(img)
lblFilmInfo.Text = ("A genetic anomaly allows a young man to teleport himself anywhere.")
lblFilmInfoTwo.Text = ("This gift leads him into a war that has existed for centuries.")
End If
I am getting a
"Method not found: 'Boolean MyCompany.LibraryAssembly.SomeFunction (System.String)'"
Exception/error when running a VB.NET console application. The method is part of an external assembly and it is definitely in the assembly. The error only occurs at runtime when I go to enter the function that calls the method. I have the assembly referenced by my project and I am not copying it locally. Intellisense shows no errors, and neither does the compiler. I am loading the assembly statically not dynamically. I reference the from a local folder (not the GAC) although the same version is also available from the GAC.
I am trying to read a text file into a text box, and show the progress bar loading. Sometimes if the text file is big, i don't know when it will finish reading it. This is basically the code i use to read a text file, but i don't know how to show the progress bar.

I am trying to select some images that I have in a folder called images in my project however when I select image url in the properties URL the image folder is not found I am only getting App Data and my project with nothing in the folders, I have copied the images to those folders and still nothing.Also I am used to being able to select images for buttons but I am assuming you can not do this in the same way in ASP?
View 3 RepliesI'm having a problem with loading two text boxes from a saved text file. I've built a log in form that saves the user-name and password on separate lines in a text file.I have a save button and a load button. My problem is that I'm new to Visual Basics and I can't figure out how to get the two lines from the file to load into their separate boxes on the form.The code that I have loads both lines from the text file into the User Name Box.Oh the username is on the first line in the text file, and the password is on the second line of the text file. Could someone please help! My Loading code is:
Private Sub btnLoad_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnLoad.Click
If File.Exists("Login Config.txt") Then
Dim ioFile As New StreamReader("Login Config.txt")
Dim ioLine As String ' Going to hold one line at a time

I am trying to create a program which reads data from a text file and insert the data in to a SQL 2005 table, but unfortunately it only reads the first line and insert correctly but not the rest of the lines on the text file
The text file looks like this
Test.txt
John, Doe, 40, 12/04/1968
Micke, Gulm, 39, 07/08/1970
[Code].....
sort out this issue as I need read the entire text file which in reality will be about 5000-10000 lines and insert them in to the SQL DB line by line.
i am using vb.net 08. I have a php file loading into a text box. and then i have an external text file. the text file looks like this:"text 1= text 2 text 3 = text 4 etc"I need the program to search for terms inside the text box that are on the right side of the equal sign and replace it with the one on the left
View 3 RepliesI picked the idea to make a little agenda for my own use and my plan was to edit a txt file using the RichTextBox. I want to use a DateTimePicker too, so that I can load a specific text file for the date chosen so that I can edit it. Does anyone have an idea how I can use the DateTimePicker to create and load certain txt files related to the same date?
View 11 RepliesI made a text file (.txt) in my project by going to Add New Item and then Text File. I want to have my text file be loaded into the rich text box i have on my form but it doesn't work. It says it can find the file. This is my code:
[Code]...
I am new here and just started visual basic 2008. I want to load a BIG file to edit the text. It is 24MB So whenever I load it in the richtextbox it shows : 7@
:/ Regular text files load fine.
Here is the
CommonDialog1Open.Filter = ("EXE [*.exe*]|*.exe|All Files [*.*]|*.*")
CommonDialog1Open.ShowDialog()
rt1.Text = (My.Computer.FileSystem.ReadAllText(CommonDialog1Open.FileName))
I know I am trying to load .exe! It will load if I save it through the program but will only show 7@.
So i have a text file that is created in the program which can be loaded back into the program(game save)
Whatever is in the text file "stats" should be listed in listbox1 in the same order it is in the text file. The same with "items" in listbox2. And then "quests" will be in listbox3.
The problem is when i load it instead of what is in the text file it says...
note that box3 is correct that it has nothing in it.
[Code]...
Getting a vibe that my VB is cursed. All I want to do is load a textfile and have the text appear in TextBox1 But no. I have looked at 3 different tutorials and I have tried copying their code word to word but still!

And it gives me the following errors:

i have code for loading a text file (comma separated) into my DGV:
If Not DataGridView1.LoadTextFile(TextBox1.Text, ErrorList) Then
Dim sb As New System.Text.StringBuilder
sb.AppendLine("Failed to load text file, see error messages below.")

I'm wondering...is it possible to run this code if the user was to drag and drop the text file onto the datagridview, rather than having to navigate via buttons etc...it'd make it a much nicer method!

I'm writing a VB.NET app where I want to load an internal text file from Resource. But the code shows Invalid URI: The Uri string is too long. The code is

document.Load(My.Resources.info)
'some processing job with XML node ...
So, how to load the resource file ?
Trying to write an app to load a Text file and then search for substrings that contains some specific characters to compose a list. Tried first loading the text file into a StreamReader then search line by line for my substrings. Had to write a lot of code to identify my strings, but it worked ok. Then tried loading the text file into a RichTextBox then use RichTextBox.Find(......) to look for my substrings. The " .Find" property makes the code really simple, but using RichTextBox the app was really slow.
Using Stream the loop was completed in about 2 minutes and using RichTextBox in about 30 minutes! I will need to make a lot of searches and using RichTextBox is lots easier, but is too slow. Is there any way to perform search operations using Streams instead making a loop and go looking line by line??? Or what else would be a good solution to search for strings in a text file??
I wrote the code and it works great but then i thought i'd have a little challenge and go above and beyond. i decided to make a highscore leader board system. i used the following variables and sub classes to make it but im having a slight issue...
CODE:
The idea is that i wanted to make the system able to associate a name with a score, sort the score from greatest to lowest, save it to a text file, load it from the text file, repeat.
so heres a quick list of what i have working...
-Stores name and score
-Sorts by score then outputs
-occasional index of -1 issue
-saves score and name to a text file
-loads score and name when the form loads
-CANNOT add new data to the sorted list...
Thats my main issue. When i have data loaded from last time i try to add a new score to the list but then it gives me an error.
InvalidOperationException was unhandled Failed to compare two array elements
-pointing to the line...
In the details of the exception it continues to say...InnerException {"object must be of type String"}
i don't know which parameter its referring to tho, the variable name is already of type string and count is type integer.
I'm learning to write text file from a Listbox and DataGridView, and read from it.Everything works fine until I have a small problem with reading file into DataGridView.

View 3 RepliesI have a few questions. Working on a program here that reads in data from a .txt file and puts it into 3 different labels during the form load procedure. I was wondering though, here's what I have so far:

Label1.Text = contents

how to do this, but I'm ignorant so I forgot, how to load lined text from a .txt file into a combobox?
View 6 RepliesIve been programming in VB6 for years, i figured its time for an upgrade. Here's what im doing, and what the problem is:
Im loading a bunch of pictures on top of one image. They are all PNG files, and some of the images have transparent edges, and some semi-transparency within the image itself.
So basically, i need to be able to load these images on top of the other images, and still maintain the transparency.
Is this possible in VB08? This is one of the main reasons i moved to 08 from vb6, more things possible including multithreading.
1) How can I load data from Text file to DatagridView. I want it because I'm making a listener. And when I load a data from text file, i want to edit rows. And this calling the second question.
2) How can I save data, Datagrid to Text file.
I found a code
Dim obj_oledb_da As System.Data.Odbc.OdbcDataAdapter
Public Function ConnectCSV1(ByVal filetable As String) As DataSet
Dim dataSet As New DataSet

I can load data with this code but I can't save.

I want to add the contents of a comma delimited text file(PracInfo.txt) into a Dictionary on Form_Load. The contents of the file are as follows:
wlvc,coadmin
mrmd,thadmin
ccoa,oaadmin
bfhl,bfadmin
trty,tradmin
nppp,npadmin
For example, I want the wlvc to be the key and the coadmin to be the corresponding value. The code I have so far goes as follows:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim sr As New StreamReader("C:Programming filesPracInfo.txt")
Dim openWith As New Dictionary(Of String, String)
Do While sr.Peek <> -1
strHold = sr.ReadLine()
' here I would like to use the String.Split method on strHold and then put that into the Dictionary using Dictionary.Add(Key,Value) but not sure how to do this????
Loop
End Sub

The duplicates need to stay as they are in the text file. I just want the duplicates deleted from the listbox when viewed. How would I do that? Say there are two orders made by the same user. I only want the user to show up once in the listbox...
