I have a webpage that is used to modify information in a database. The information is properly pulled from the database and properly displayed in their appropriate text boxes. The problem arises when i change the information and try to resubmit it to be saved. Unfortunately it never takes my edited information and reverts back to the original value that was loaded when the page was loaded.
All of the code has been tested out side of the masterpage and it is working properly so i am under the impression that it has something to do with the use of the masterpage. If my understanding is correct i cannot just do something like me.txtName.text to address an object in the content pages. So here is a snippet of the code and the portion that i am assuming has a problem.
[Code]...
The code shows the two methods that i have used to try and use findcontrol to access the text boxes. Both methods seem to locate the textboxes but once I pass the values to linksUpd it reverts back to the value that was originally loaded into the page and discards all of my changes.
I have a label in a master page (sample.master) called lblHeading.I want to dynamically change the text of the label when I load the content page.I need to do this because I want to change the heading to something meaningful but only after I know about the content of the page.
I'm new to databases under vb.net although I've used them extensivley under VB6.I have a main form with a DataGridView on it. Thats connected to the following bits- _TWC_Viewer_SubmissionsDataSet, ViewerDataBindingSource, ViewerDataTableAdapterm and TableAdapterManager. All this was etup by the VB wizard. The database table is named ViewerData.This all does it job very nicely.
Secondly, I have another form which is setup so that when you click on a main form record line it opens up the second form for in depth record editing.The second form is a bunch of text boxes ect to represent each field.This form has its own set of database bits- _TWC_Viewer_SubmissionsDataSet,ViewerDataBindingSource, ViewerDataTableAdapter, TableAdapterManager and ViewerDataBindingNavigator.This form also works fine and does what it should.The problem is with a 3rd area. Its all in code and creates its own temporary dataset. After its done its job, its saves its results back into the database which also works ok.However, the changes in teh database are not being reflected back to the controls on either form. If I kill the app and restart it then the updates are in the database so its just a form updating problem.
I have an access database that I would like to add a row to. Contents of the row are entered through text boxes. The problem I am running into is the data is not being saved to the the dataset. It only saves to the TableAdapter and is visible in DataGridView.[code]
I have a datagridview with a checkbox column at the beginning, what i want to happen is that when I press the Ok button it will update the Requested row in my EquipmentDetail table with the corresponding checked chekcboxes.
The problem is that when I check even only one checkbox All of the rows are updated into true even if its not checked in the datagridview
I have this Quiz software that lets you create online multiple choice quizzes which are great for studying (I am in grad school and I'm trying to use everything I can to learn). So the Quiz software is great but it only lets you input questions by hand, one by one. I took a look at the .xml file that the quiz program spits out and came up with the idea to try and make a converter so that I can import many questions at once. I was hoping to try and solve this limitation by doing the following:
Take a .doc that say a tutor gives us with a bunch of practice questions, and then take that into Crimson Editor, and then format it so the question is on line 1, the multiple choice answers are on lines 3,4,5, and 6, (for the next question, the question would be on line 11, and the answers on lines 13, 14, 15, and 16, and so on) and then take that saved .txt file into my program, hit the generate button, and it will spit out the .xml file, and then import that into the quiz software to generate the online quiz.
Here is an attached screenshot of my program layout so far:
I figured out how to open a text file by watching simple youtube tutorials, but I don't know how to have it generate the stuff and have it show up in the bottom text box. I know how to do the coding to convert the txt to proper xml code but I don't know how to be able to save the contents of the bottom text window to an xml file.
its noobish question but i didnt find any solution for it here is my problem : i want to write bites from 2 seprated file (1.txt + 2.txt) into 1 single file(3.txt) but i cant
I have a patient register form in my project...When the patient details will be saved in the database it should also be saved in the text file...I am dynamically creating a folder with patientid and firstname in that folder I am creating a text file patientreg.txt and it should contain the contents of text file....
I have wriiten the below code but I am getting an error.... Dim di As DirectoryInfo = New DirectoryInfo(Application.StartupPath & "" + txtPatientID.Text + txtFName.Text)
I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
I am writing a simple program that will encrypt the text that is held in a text box and save it to a text file but I want it to be able to open a text file and decrypt the contents.
Ok now all the threads I have read are about reading a text file that is in a preset location.
What I want to do is open a text file that the user selects and have the contents displayed in a text box.
I am creating a new page in VS2005 (VB) and it has a gridview, my problem is when I try to insert the grid into the ContentPlaceHolder (in design mode) it ends up somewhere else on the page all together.
I've used IPostBackEventHandler on pages in the past for calling the RaisePostBackEvent in my code behind via javascript.I'm currently working on a project that requires the same functionality but would be pretty cool if I could put it in my MasterPage, I've tried similarly it identically but I'm having no luck, I wonder if someone could point me in the rite direction.[code]It's something I don't really want to do on each and every page that uses that MasterPage.
I am posting this on behalf of a mate so repose from me might be delayed.

I am building a program to populate an Excel invoice template. The program works for the most part, except for one odd flaw. The program calls a module which first checks that two text boxes on a form have been completed. However, whilst the program does see when one of the text boxes has not been filled in (txtContact) it doesn't see the other (txtCustomer) even if I change the name of the text box to check it still only responds when the the other text box is empty.

make a diary style application where a password must be typed in then when that is typed in it is possible to view and edit the text. I have it all working but the only problem is that I don't know how to save the text box's contents. I have read a few threads and haven't found an appropriate answer. The problem is that since it's supposed to be a diary I would like to save the text so that it may not be read, preferably not by making another file but by storing it in the program?
Here's the code I have for it so far:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Password As String Password = TextBox1.Text
[code]....
Textbox1 is where the password is entered, Textbox2 is where the actual text for the diary would go, Button1 processes the typed in password, Button2 hides the text and clears password box, Button3 does nothing and has the text "Save" and I would like to use this button to save. Is there also an automatic way of saving?
I have a problem that my jQuery don't load or something when i'm on the contentpages.When i click on the link that should load the jquery,it only works at my startpage (Default.aspx). And when i click at the same link that is placed in my footer on any other contentpage, nothing happens. So i guess something is wrong with the paths or the loading of my scripts.Here is my scripts in the masterpage .
I have a Master Page with nested pages in ASP.NET. Fairly simply I want to databind some hyperlinks to a gridview for the master page. This however is throwing a null reference exception when I try to set the DataSource.
I tested the code on a separate page and it works as expected. When debugging I can see the Page_Load Sub hit twice, I don't know if this is the cause I have one nested page being loaded, this is a blank page at the moment

For my masterpage, I embedded an image on HTML DIV. Background image did appear, but with 4 white border-like surrounding my image, where I didn't apply any.
I have a MasterPage,defaultPage and Cropper page and I am able to use JCrop when I have only default.aspx page and not master page and the cropper page.
Problem:When I have am having masterpage then I am unable to use the Jcrop as it is not showing the Image Cropper rectangle.
I have some processes that run as a background job, allowing a user to continue to use a page, when the jobs are finished (which can take a few minutes) i want to display a message to the user, the best place to display this would be the masterpage AFAIK (incase they move from page to page on the site) so i have defined a div in the masterpage file.
I am trying to find the best method for displaying the data, at the moment i have a method in the masterpage vb file which polls a database to see if the job(which involves complex logic and some db access) has completed, if it has, it shows a message in the div e.g. "Job 13132 has completed" - which works fine.
The problem is this is not dynamic, and i have to refresh the page to call the function that checks if the processes have finished, how can i use AJAX to deliver this content automatically every 5 seconds?
I have tried using an asp timer with a 5 second tick time but the entire page refreshes on the timer click event every 5 seconds.Protected Sub Timer1_Tick(Byval sender as Object, Byval e As EventArgs)
[Code]...
Is there a way to only refresh the div with the updated message, without a full refresh happening using this code? Or if this is not possible, is there any way to replicate the above function using jQuery and still be able to update the DIV text only if a job as finished?
I am a beginner using Visual Basic 2008. I have a problem and can't figure out the code for the following. I have a form that contains two text boxes into which the user types information. When the user clicks on one of the textboxes it becomes blank and it's contents are displayed in the other text box. I seem to be using the correct codes but can't get it to work right. Does anyone know the correct code for this?

With this code, I tried to put the contents of a collection (Info) into a text box but it didn't work. I would be glad if someone can examine it and tell me what is wrong. (Visual Studio builds the program fine and runs it, but when I click on Button3, this comes up:
An unhandled exception of type 'System.ArgumentException' occurred in Microsoft.VisualBasic.dll
Additional information: Argument 'Index' is not a valid value.
Here is the code I used (When the error occurs I made it bold):

I need to scan all files on our solution (aspx, js, ascx, etc). Our solution contains 22 projects all in all. What I need to accomplish is to search for all files which contains "img=" in its content (not filename containing "img") I don't want to do this manually of course (opening and checking files one by one). How I can do this faster.
