My boss has given me an asp.net web application that was done by his former employee. Now my boss has no contact with that employee. He wants me to make some changes in that web application. I went through the application. There is no documentation present for that application . Its a huge application. It contains many directories. I think it was a team work. It has many asp pages, aspx pages, jsp pages, xml pages, css pages, etc... How to understand other person or team's website or web application that was written in asp or asp.net and vb or vb.net?
I have problem. I have site.master wich includes coulple of user controls. Now I need to pass value (srting) from actual pages code behind to master pages user control (Property) .
I am having trouble passing variables between forms. Ive tried many methods but none seem to work. The first method I tried was to dim a public variable on the first form and call it on the second....no success
Form 1: Public cliCode as string cliCode = me.tbClientcCode.text
Form 2: dim clientCode as string = form1.clicode or
Form 2: dim clientCode as string
On the Form2 load event.... clientCode = form1.clicode
With method 2 I created some classes on which form 1 loads and form2 access........ Public Class frmClient Private db As New ClientDataContext Public clientInstance As New BusinessLogic.classClient Public cliCode As String [Code] .....
I know this should be easy but I'm either having a brain fart or I'm just more inept than I thought; probably a combination of the two.
Passing a value to a form on startup is a piece of cake, but I don't think I've ever had to do the following before in all my ooooh, 8 months of programming:
I have a main form with a button and a textbox. The button opens another form with a datagridview. What I want to do is pass the selected value from the DGV back to the textbox on the first form.[code]...
I'm practicing creating a website for a test, although I am having trouble passing varialbes between the webpage with which the user logs in, and the web page in which the user sees/amends their details (it's an online bank).
Basically, I want the user to enter their customer ID and password, then click on the 'Login' button. When the user clicks on this, I want to display their details based upon their login info (ie their own, and nobody else's bank details).[code]...
if this is a dumb question. I don't ever have to write anything in VB.NET.But I am passing variables named "name" to a function and sometimes it may be 1 name or 2 names, etc. I want to check in the function if its only 1 name don't add a comma, if it's 2 names add a comma. Is there a way to get how many "names" there are?
EDIT: Added my ode to make my question a little more clear. sorry for not doing it before.
My Code:Public Function GenerateCSV(byval str as string, byval str1 as string, byval str2 as string, byval GrpName as string)
I'm working on integrating my companies back-end system with paypal, on our current website.I have done paypal integration before, but this company is a middle-ware provider that allows us to hold an order until it ships.They have provided a very low-level example of implementation, but leaves some gaps in a true implementation on a back-end system. They have each method, essentially, have it's own aspx page that sends data to a page, that contains a javascript that autoposts to a url, with 3 hidden variables.
Passing variables from .bat file to vbscript. I have .bat file that launches test.vbs. I need to pass variable defined in the batch file inside the .vbs file.
the batch file contains the code
set /p var= please enter the value: cscript test.vbs "%var%"
Where as test .vbs has the following codes
Dim StrText MsgBox StrText
In my requirement value assigned to variable 'var' in batch should assign to StrText variable in the test.vbs and then it should display in VB message box.
Is there a way to pass variables into a form that is shown as a dialog?Dim frmCreateCSVFile As New CreateCSVFile Dim returnValue As DialogResultreturnValue = frmCreateCSVFile.ShowDialog()
It doesn't seem to find the variables when I use the form name.
I am writting a VB .net (3.5) applivcation which references a COM object. I can call methods on the COM object fine provided that they don't require any variables to be passed. I have been told that you can only pass a maximum of one varaible to a COM object, I really don't believe that it true
I have a project that I have set up a menu item Setting witch calls a Dialog calledDialogSettings on this dialogI have a tree view that selects a user controls that I can change the settingsbut I am having a problem passing variables to and from the main program to the UserControll so I'm unable to show what the setting is and unable to change the variable that the setting is for
What is the best way to pass a variable from an OnClick event. To elaborate I would like to bind some data to the button and then when that button is pressed I would like to pass that data back to the code behind and do something cool with it.[code]...
I have a gridview and use a session to pass the variables from the page to an edit page. This works perfectly, until you search for a number. When you search the correct record displays in gridview, but when you click edit, it passes the wrong record.
Private Sub gridview1_RowEditing(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs) Handles GridView1.RowEditing Session("wr_id") = GridView1.Rows(e.NewEditIndex).Cells(2).Text & "~/~" & _ GridView1.Rows(e.NewEditIndex).Cells(3).Text & "~/~" & _ GridView1.Rows(e.NewEditIndex).Cells(4).Text & "~/~" & _ [Code] .....
I realize not all of the code is pasted in here, because it would take too much space. Any Ideas? I'm guessing it has something to do with e.NewEditIndex
I want to pass a few variables to another page. Currently I'm using response.redirect and passing the variables in the url. I'm not really interested in using Session Variables. Is there a way to pass hidden variables in .NET to a completely different form?
I am developing an VB.NET application that reads data from the serial port and tcp socket, then I'm processing this data and store it in Database server. This application will be started all the time as long as the computer is started. On the server there is installed an apache server with some php scripts representing the "visual interface". From there the users can see the readed data from the VB app. The need is when an event appear in the apache server (such as button pressed), some data to be passed to the running VB app, and eventually trigger an event on it. I've considered some variants like start an timer that reads continuously some tables from the database that the php script writes onto, or read an xml ot text file, but I think that this may slower the communication and it is a source of exceptions or errors.
For example: An user opens a webpage, just to say test.php. On the page there is a button. The user pushes the button. The result of pushing the button has to trigger an event on the VB app and cause sending data trough the serial port or tcp socket. OR - The VB app has a timer that scans for pressing the button on the test.php.
I am using Stanav's PdfManipulation2.AddImageToPage(..., Pages) for iTextSharp library (v5.1.3) and was not able to add the image to specific pages: e.g. to add to only page 1 and 3 of a five pages PDF
Dim Pages() As Integer Pages = New Integer() {1, 3} PdfManipulation2.AddImageToPage(..., Pages)
Calling AddImageToPage() with the the optional Pages parameter will add the image to all pages though.
I have a form on a .NET webserver using aspx pages with the vb code-behind pages. The form collects the entered data and then emails it, that part works fine.Right after it gets emailed, this code checks to see if the email was sent or not and then updates the landing page accordingly. I used to use just an IF THEN statement, but now that doesn't work in these new .NET pages. Here's the end of the code that I am having difficulties with:
I have heard of setting server specs to have HTML pages parsed as PHP pages by changing the .htaccess or httpd.conf files. Is there a similar solution to have HTML pages parsed as ASPX pages?
A website I am working on does not want their PageRank to lower since their HTML pages are already indexed and used on other websites but wants to use some dynamic features of aspx pages (like include the navigation file so that changes to the nav will only have to be done in that one file).
When working with a collection of forms that the user must step through, is it better to pass the data foward when creating a new instance of that form, or is it better to call a function from the previous form? I have some code written that calls the previous routine, and it looks ugly, and I can't quite think of a reason why it was done that way. The only reason I could come up with was if the data was large, and there was a good chance that the user wouldn't use the data except in a special case.
i have this program which records the every printing made on a local computer.I am to record the number of pages of the document to be printed and the number of printed pages. i have this code but i don't know the number of pages and number printed pages always return 0 [Code].
Last year (2010) I came across a FANTASTIC command that allowed me to take a string of variables with a common delimiter and break it all back out into separate variables (possibly an array) with one statement.
[Code]...
As long as the delimiter was a unique specifiable character, this one-statement command could break it out into elements. my memory and point me in the right direction.
I have code, shown below, that works all except for 1 thing: The variables being passed byRef get passed, but once modified in the else section of the "if me.invokerequired" code of RecordData, the variables are never updated in the calling function. To reiterate, the calling function does not receive the updated data that is in the variables custid and amt.When debugging, I see the data change in the else section of "if me.invokerequired", but once it returns from the callback the data is missing.[code]
I define some global variables of a class as follows:
Private Class MyClass Private var1 as Decimal Private list1 as List(Of string)[code].....
But I found that after this form is closed, all above variables, var1, list1, list2 still exist in memory. I thought they should be collected by gc since the form is already disposed as I confirmed.
Add: I have monitored half an hour after the form is closed. But these variables are not collected by gc. I have an automatic update procedure on the form which uses above variables.Since the above variables still hold values, the automatic update procedure is always called which causes exception. (One quick fix is to check if form.isDisposed in update procedure. But I do not think this is elegeant. Besides, these variables occupy memory.)
Table2 should be updates from table based on the results... If all results is PASS then the table2 should be updated as pass... if any result is FAIL then the entire case_no should be updates a s fail..
This code was working consistently, but now...This code works on the first pass.Then second pass it just hangs on Code:Dim tcpClient As TcpClient = tcpListener.AcceptTcpClient() for about 2 minutesThen the code will fork for another pass, then fail.....
Does the memory used in declaring variables are reclaimed by the OS when these variables go out of scope?Does the memory used be released by setting thier value to nothing? if not, then how can I force the garbage collector to run or excecute at a certain/desired time..How about in Windows Forms..How can we make sure that the memory used in initializing and showing forms be released if those forms were closed?
Question 1: What is the difference between "Background Worker" and "Worker Pool" as indicated within the MSDN samples provided.
Question 2: I noticed while using, AddressOf _Function_, variables cannot be passed; what would be an efficient solution to this?
Question 3: While using multithreading is it required to invoke before setting variables, or only form properties?
Question 4: While using System.Net.Sockets is it safe/efficient to use Application.DoEvents while waiting for new data; or would be using a Do While loop be fine without DoEvents since the action would be multithreaded? Note: there can be up to 2000-3000 sockets in use at a time.
