I'm creating a bookmark library cause my friend requested but I do not know how to make it so that you can add bookmarks while you are inside the program and have them stay there even if you close it.
View 4 RepliesI am using VS 2010 and I want to read the Text File values and place them into variables. This is my code
Me.OpenFileDialog1.FileName = Nothing
If Me.OpenFileDialog1.ShowDialog = System.Windows.Forms.DialogResult.OK Then
Me.TextBox2.Text = Me.OpenFileDialog1.FileName
filename = Me.TextBox2.Text

In a Word automation project in Visual Basic 2005, I am trying to reference a bookmark in the bookmark collection using its index. However when I try to do this, the program aborts with the message that "The requested member of the collection does not exist". I am using the index so that I can refer to the subsequent member of the bookmark collection from the one matching my selection criteria. Here is a snippet of code which causes the error. In the listing below, the Debug line causes the error.

I want to store a fairly large amount of static data in a class library.I have used a library before that does this, containing info for thousands of items. The person who made the library got that info from a database and somehow stored it in the library such that you could access it in a variety of ways using different methods. (ID, Name, etc)

View 1 RepliesI try to insert formatted text into Word bookmarks. The text comes from several rich text controls (we use TX Text Control) and is appended into a bookmark. The problem is that the tags are written as-is and are not interpreted.

Need to store JPG/GIF picture files in an access database table and then would like to retreive it and put it on a Word Document using VB 2005 code.
View 17 RepliesIn Java you can store a class in a separate file and instantiate it from a method in another file as long as the class file is in the same directory but this doesn't seem to work in Visual Basic.
View 1 RepliesI am in front of a great dilemma whether to store files in Database or doing it the standard way. I would choose the second option, but my application will be used by multiple users, so I am doing it by Web Services.
On the one hand, storing in database will be very useful as every user would have access to everything very fast, not caring about file paths, locations and so on.
On the other hand, if this table consists of 1000 files, wouldn't it be a bad idea as there should be some performance loss?
At the present moment, I am using mysql as database, but I am thinking of moving to SQL Server, but I suppose this is not DB Issue.
I am making a program that stores information for my applications. There are 4 main things I need in the XML file, the login information (User name and password), Application names and keys, and the owner of the application (who bought it). The program allows the user to enter as many applications and owners as they want and once login information is correct it loads the data. Then on exit all the data saves to a XML file.
My XML file looks like this
<Data>
<Login>
<UserName> (UserName) </UserName>
<Password> (Password </Password>
</Login>
<Applications>

How could I go about doing this if I can? Storing files into an application compressing them and then extracting them?
View 1 RepliesI'm trying to host some static files for access by an ASP.Net web role and a separate data worker role that are both running on the same deployment (they use a global static interface).
However, I'm unsure how exactly to 'host' them, I've tried using virtual folders via HttpRuntime.AppDomainAppPath, but it only occasionally works in debug mode. The files also don't seem to get packaged into the deployment packages made by VS vis CSPack (though this might be a separate issue, is it possible to fix this too?)
The static files in question are actually WordNet, which I'm using through WordNet.Net, If that makes any difference. I also need the solution to work in both the cloud deployment and the emulator (if possible).
The user will basically be able to select a file on their hard drive, and enter some details or info about the file and then save it
View 2 RepliesI need to unzip a list of .Z files which will be kept in a folder using Visual Basic.NET. For example, consider that there is a folder like C:FilesToBeUnzipped. Inside this folder there will some 5 to 6 files with .Z as extension. I need to unzip all these .Z files and save the unzipped files in a folder like C:UnzippedDataFiles.
Is this possible in VB.NET? Is there any free component or class library to achive it?
I have a .NET customer framework that functions much like a Workflow. It uses reflection to get a listing of all of the processes it is capable of from a specific folder, and starts them via reflection with a known start point (all of them have a method called "Process"). Since these files are only called to do the processing and not part of the compile... is there a way for me to be able to drop in a new reference library (DLL) for one of the processes that is being updated without restarting the whole process?[code]...
View 1 RepliesSay I have a Class Library project with its own .dll.config, and a forms application. I want to confirm that it is impossible to reference the .dll.config file from the .exe.config file and still use My.Settings.
For example: I have SomeClassLibrary project, with SomeSetting that I can access through My.Settings.SomeSetting. I also have SomeFormsApp project. This is what I want my SomeFormsApp.exe.config to look like:
<?xml version="1.0" encoding="utf-8" ?>
<configuration>
<configSections>
[Code].....
From my readings, this seems impossible. I either need to copy the content of SomeClassLibrary.dll.config into SomeFormsApp.exe.config, which is tedious and error prone when copying from multiple class libraries, or I need to use ConfigurationManager, which bypasses My.Settings and its typed, Intellisensed goodness.
I am writing an application for editing pdf files with this library: [URL]. The problem is that I had to format pc because a trojan and since that moment every time I try to continue my project I can't use the library. The code its the same as it was before formatting, but when I compile the code and the application runs I get an exception every time I try to use a library function.
Some info:
I'm using visual studio 2008 .net FW 3.5
vb -net language
I'm using a W7 64bit environment (before formating was W7 32bits, but I tried to use a 32bits OS and the problem remains). I've already registered the 2 COM components (Img2PdfAPI.dll and pdprep32.dll)
regsvr32 "C:Program Files (x86)prepToolspdprep32.dll"
regsvr32 "C:Program Files (x86)prepToolsImg2PdfAPI.dll"
Solved: Was because of the license.
I'm attempting to create a little library to encrypt and decrypt Files with AES. There are loads of examples of how to do this on the internet so coding is not a problem. There are however a few questions regarding cryptography and AES in general.
#1 Does the IV need to be kept a secret like the key ?
#2 Can I just hash a string with SHA512 to make a key for AES ? or do I need to use PasswordDeriveBytes ?
#3 In the case of me using PasswordDeriveBytes Do I need to keep the salt a secret ?(or do I need to keep it at all)
#4 Can I generate the IV from the same password that the Key is derived from ?(if so How ?)
My program I wrote is using Outlook 12.0 lib for Outlook 2007. I have referenced this in the project. This exe will only be installed on computers that has Outlook 2007 on it. So with this being the case, do I need to bother including any of the lib files? Or just my exe?I have this in my form:
Imports Microsoft.Office.Interop
Imports System.Reflection
Imports System.IO
Imports System.Text
[code]....
So I assume the Interop is all part of the object lib? I know this sounds crazy but I tried coding it using late-binding with many examples but just had too many problems. So I'm going to make three different exe's for versions 2003, 2007 and 2010.
I am trying to create a sort of code library in visual basic where the form displays a list box of certain project files in vb that i have made in the past and when clicked, launches the .exe files of those visual basic program project files.I know it does not work the same way as writing/ reading text files to vb and it seems as simple as 'on click, launch .exe of selected string "vb program 1" and so on. I am having trouble getting started on this one. Im sorry I cannot provide any starter code bc I only have a basic understanding of in/out text files which wont work the same way with .exe

I made a Class Library project that contains the main classes that my Main Project needs because I don't want to main classes when I distribute my project. I've successfully called and used it in my Main Project. But when I started debugging and stepping through my code which involves calling and using the class I wrote in my Class Library, I noticed that the class' file in my Class Library opens up during debug mode.
how can I prevent the Class Library's files from being opened during my Main Project's debug mode?
Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata

Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.
On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.
View 1 RepliesI would like to make a simple code that counts the top three most recurring lines/ text in a txt file then saves that line/ text to another text file (this in turn will be read into AutoCAD's variable system).Forgetting the AutoCAD part which I can manage how do I in VB.net save the 3 most recurring lines of text each to its own text file see example below:

View 6 RepliesI'm trying to read data from a text file with multiple records and fields separated by tabs to store into arrays, which I later want to output into a textbox on the form.

There are no error messages, it just exits? I'm not even sure if what I've written is possible. Here's what I've written so far:
