Maintaining Hyperlinks Via Streamreader?
Jun 12, 2009
I need to build a program that combines many different .doc files based on which check boxes the user selects. At first I was going to use the word.document.open(file) way, but I would rather not have to open 40 different files every time the program runs. I then turned to streamreader, which works great for basic text (after I convert the file to .txt) but I can't figure out a way to maintain hyperlinks. I am now thinking that after the streamreader reads all of the data and combines it into one string, it will paste it into a word doc and somehow search for hyperlinks and make them active.

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?

conn = New SqlCeConnection(connString)
Dim strQuery As String = ""[code]......

I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.

My program references a specific object that is contained in a list. The references point directly to the object itself, instead of its position (index) in the list, since that might change over time as other objects are added/removed. However, occasionally this object is edited, and (behind the scenes) this sometimes involves replacing it with a newly-created object (so the code looks like ListA.item(i)=new testobject...). In which case, if my understanding is correct, all the program references to this object are no longer correct, since they point to the replaced object instead of the new one. So I'm wondering how to maintain the integrity of the references, since the list index is not permanent, nor is the object reference technically permanent. Should I create some ID number for the object, and maintain and use it for references (so the new object would get the old one's ID)?

One of my programs uses transparency so that the form is the shape of the background image (.png). My problem is that everything works and looks fine on the computer I'm developing on (Win7) but when I run the program on my other computer (XP), instead of the transparency I get the background color (which is the same as the transparency color). Does anyone have any experience this problem?

I want to add an if statement that checks if there are no hyperlinks in the document and if there are no hyperlinks display a message that there are no hyperlinks in this document.The problem is that Word is divided in stories, so the body of the document is a separate story from the footnotes story of the same document.So when I attempt to check for hyperlinks the if statement checks the body of the document first and if there are no hyperlinks in the body, then exits the program even though there may be hyperlinks in the footnotes story.

I am extremely new to Visual Basic, and I have only so far made an e-mail sender and an SMS sender (through e-mail).
So I am having troubles, I made a quick Web browser that I only want to show one page when you press a button ( you have to enter a name into a textbox and it will then make the URL to show), but the page has some links on it, which I don't want people to click on.
1) Disable the hyperlinks
2) Disable left clicks in the browser
3) Make the browser somehow only visible and not actually interactive with a mouse
I honestly have been searching for hours for a solution and also trying different things, but to no avail.[cod]e...

I am sorry if this is in the wrong section (vba, similar to vb.net but many differences) but I couldn't find a forum for excel vba code.
how can I get my vba macro to search a webpage and find a specific hyperlink? I can get it to retrieve data from tables but to get some data I need it to take part of a string from a hyperlink location.

I am working on a new domain model for an application that will have order processing for items built in (well, too keep it simple for this question anyway). I have a class "VendorItem" that represents items that can be ordered. Originally the "Order" class was going to have a list of VendorItems associated with it, but I have come across problems with it so far.
Let's say that the system has been creating orders for some time just fine. One day a user comes along and decides that a vendoritem has changed price or some other detail like packaging size. I wouldn't want the previous orders to be affected by such change. At first wash I was going to make a "OrderLine" class that is basically a copy of the "VendorItem" class, but that just feels (smells?) wrong in the OO sense. Is there a better way to refactor this so I don't have copies of classes and information in the domain model?

I have three radio buttons defined within a frame (optRptType_0, optRptType_1 and optRptType_2). I set the checked value to true on optRptType_2 to use as my default. I have the following checkchanged event defined for these radio buttons
[Code]...
When the form opens the optRptType_0 is checked. I am trying to determine why the optRptType_2 is not checked as that is the default I set up. I tried adding the line "Me.optRptType_2.Checked = True" to the Form Load event but it had no affect and the optRptType_0 is still the entity checked when the form opens.

I want to make an interactive CD, and I am using Richtextbox in it. I have problem with hyperlinks in Richtextbox. I loaded the content from .rtf files. I have hyperlinks in these files. The loaded hyperlinks aren't working. The mouse changes when CTRL is pressed, but nothing happens on CTRL+mouse click. IsDocumentEnabled is true. Perhaps I should make an event for hyperlink mouseclick, but I don't know how.

I have the [B] [I] [U] buttons and they work to a point but here is the problem I'm having.In MS Word,I can Hilight text and select Bold and it bolds the text, I can then select Italic and while leaving it bold, it Italicizes it.I can then click the bold button again and it will remove the bold but leave the selected text Italicized. I can't figure out how to get this action to work.I know I can OR the styles to apply multiple styles to the text but I don't know how to remove a style while maintaining any others applied.Here's a section of code that I'm messing with.[code]....btw, I am using for the comments so that the code is easier to read.I have tried (in this specific segment) newFontStyle = currentFont.Style And Not FontStyle.Bold

I am currently trying to, using VB Express 2008, change some hyperlinks in a word document. The words which are associated to this hyperlinks also have bookmarks which I use to access them easily. The error I'm recieving says "Range is not a by reference property." [code] The error is produced by that last line. The full code is actually longer and it also runs through a process with Excel where it determines de variables used.

I have been puzzling over this for about 2 days now but to no avail.All i am trying to do is retrieve all the "<a href = "myLink.php">MyLink</a>"
I can do it via the webbrowser with getElementsByTagName but i just cant for the life of me work out how i split the returned html into either an indexed array or just use inStr or Split function to split this into seperate value, But if i have a csv file with 20 links i dont want to have to load every page into a webbrowser control just to use getElementsByTagName.
Now it all works fine and retrieves the source code from the page. I have only extracted part of the code which is relevant to the retrieving html to try to shorten this post.

I have an issue with maintaining scroll position.I am almost positive that I have everything set correctly. I have updated my web config...
<pages maintainScrollPositionOnPostBack="true"
and everything seems to work fine UNTIL....When ever my Gridview returns a lot of pages, like more than 50, sometimes upwards of 100 or more, I show 50 records per page. The farther into the Gridview, the more the scroll position is off.So what I am saying is that for the first 20 plus pages or so, if I scroll down the page to the point where the top rows have moved off the screen and I enter Edit Mode, the correct record remains in view on Postback.But if I am over say around 30 pages into the Gridview, the further in the worse it gets, when i enter Edit Mode I have to scroll back down to the location of the record that I selected to edit.

I have made an employee list and linked it to an Access database. The initial problem I was having is that in my program I had to link their ID's and names so if you click on an employee in the listbox, his or her's ID would automatically display in the textbox below. Since I did not know how to do so, I decided to make an array and store the ID and names separately while the listbox is being compiled. And so, the form became linked and adding became easy to code.But my problem came in deleting an employee. When deleting the name should be removed from the list, but this is where the order of the arrays messed me up. How do you maintain the order of the array? Here is the code I used. I dimmed 'count' as an integer and it is responsible for keeping that order.[code]You will see Staff_CodeTextBoxes etc. and info_Staff_CodeTextBoxes. etc.These text boxes (not visible to the user) are responsible for holding the data while the array takes the data from it, or adds it's own data to it.

My ultimate goal is to allow users to select a file from a dialog as if they are uploading a file. Instead of file being saved to the server, a hyperlink will be generated from the file's path.This hyperlink will then be used on our intranet page in order to open the file located on our network share.Is there any practical way to accomplish this?I have tried both an HTML file type insert and .Net's FileUpload Control but neither will work since for security reasons the full path of the file is never accessible.

In a label box, I want to list a couple of websites, email address along with some text. How do I go about it?
Potential uses- As a Help > About dialog box where websites, email of the author can be listed.
To make things as easy as possible for the user, and encourage visiting of the mentioned websites.
Simple text will be ignored, while standard blue color, underlined text with hand mouse-cursor will need no thinking on user's part.

Launch a dialogue window from the main form, and then another dialogue window from that dialogue window. If you close the second dialogue window and call dispose the main form vanishes under any other open windows. This doesn't happen by closing a dialogue window normally, but I am attempting (rightly or wrongly) to stop memory useage creeping up by disposing of it.
So, the question is - what method can be employed to maintain the position of the windows?

I have a picturebox on a form. The image in the picturebox is actually a report. I want it so if the user clicks on it it will zoom larger --- while the picturebox remains the same size. Of course, the entire image will no longer be seen. So I also want to be able to drap this image around with the cursor. The examples I've found for picturebox zooming cause the picturebox itself to get bigger and smaller. I need it to be like an Access report. Click on the report and it gets bigger. Click again and it goes back to the full image. Does anyone know of an example or tutorial in VB.Net for this type of zoom-with-fixed-size picturebox function?
