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?
View 4 RepliesIs there a way in vb.net to check whether new memory pages have been created inside a process(such as winlogon, svchost etc) For eg : if i there is a certain value that may change if new memory pages are created inside the process. Then i can compare the previous value and the new value (after pages have been created) and make it sure that new pages have been created inside that process.

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 am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click

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).

I am supporting an application, which uses lots of String concatenations and I believe this is the cause of a memory leak which eventually causes an OutOfMemory exception. Please have a look at the code below:
Public Sub ConcatenateString() As String Dim Test1 As String
Test1 = "Hello"
Test1=Test1 & "my"
Test1=Test1 & "name"

I believe there are nine Strings in memory at line ten as String is an immutable object, but only one reference to the String Test1 that contains: "Hello my name is Joe Blogs what is yours?". My question is; are all of these Strings picked up by the garbage collector when they go out of scope? i.e. when the sub routine finishes running. I seem to have a memory leak and am thinking that I should really be using a StringBuilder object.
I have a client application that connects to a WCF service, i get the file size from the server as a long value then i convert it at the client to a string so it appears like ex:52.21 MB the application gets too many files sizes every time user changes the directory pathso the question is :should i convert the values to a string format from WCF service app then return it to the client as a string format or should i just return the size as a long value and let the client to convert it to a string format in other way which value take more bytes in the memory:

I am struggling a bit with a string conversion. My platform is VB in Visual Studio 2010, windows form application. What I have is a Single float that occupies four characters of a string. Where Chr(0) is the LSB of the single and Chr(3) is the MSB of the single. This string is loaded by a built in function that communicates to an external microcontroller via tcp/ip that I do not wish to modify. I am having trouble figuring out a way to get these chars from a string to a single data type. I dont need to convert the data, just move it. But I keep getting type errors and not sure how to handle it in VB.

I want to store in a string the name of a component without using the component itself. I tried the following
Private Sub CmbPriceList_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles CmbPriceList.KeyUp

End Sub
The above code returns the type of the component (here it returns 'Combobox'). But I want the name of it.

I have been using GCHandle.AddrOfPinnedObject to get the memory address of the string, but it gives the the memory address of the string data, not the string class/reference that i need to change to allow me to use this approach.I am aware that strings are immutable and can not be changed (Actualy, you can, but its not recomended), but I do not want to change the actual strings, but change the reference to it (the string object).Is there some other way to get the address of a string object reference?
