I have some problems with the SHA1 hash value of a string. I'm trying to send a file from a client written in VB.net to a server written in PHP. My problem is that when I pass the same string to VB.net and PHP, the SHA1 value calculated by VB.net is completely different from the value calculated by PHP.
For example, I want to encode a string in Base64 and then calculate the SHA1 Hash of the Base64 string. When the computer executes this task from the vb.net version and from the PHP version I get two different SHA1 values, even if apparently the Base64 encoded string is the same:
VB.net: 2E97A53B09C482A831540B532845BCAC79BFACCF
PHP: 350A2080264E2724D4BCBC521C35264D264A1DAF
I'm surely missing something, could you point me in the right direction and tell me what I'm doing wrong here?

View 18 RepliesI just changed a control on a form from a masked textbox to a normal textbox because I wrote my own code to validate the data. I'm trying to clear the leading spaces that were created for this column in an Access database using the LTrim function and it doesn't work for some reason. The column is " :30" in the table and when I LTrim it and save the changes, it's still " :30" , not ":30". Is that leading entry not a space character?

I am building VB.NET application that takes data from text files that are exported from a legacy DOS program. These are written to a datatable and displayed in a datagridview. Right now my code simply loops through the datagridview and inserts the data into the database (SQL Server). There is a requirement now that the client number must be checked before the insert to see if it exists in the database. If it does, then the value of one field (tax rate) is checked against the value of the field in the datagridview. If there is a difference, then the rate is to be updated in the database and the data that was in the database is to be written to a history table for audit purposes. If the client number is not there, then we are to do the insert (which is already written). I want to know what is the most elegant and efficient solution for this problem.
I need to compare what is in the database table with what is in the datagridview, update the history table for records that exist, and then insert new records.
1) How do I use cookies obtained from login to do subsequent requests? e.g. Login to a forum, then use the cookie obtained from login to access User CP and change settings.
2) How do I parse HTML via HttpWebRequest? Does mshtml work with HttpWebRequest? If so, how do I work with it? I thought of downloading the source code of the page I'm requesting into a richtextbox and do my stuff from there, but it sounds kinda impractical to me since I have to use regex to get the innertext of stuff (or not?).

I am very new to vb.net. I have been using vb6 for a while and I am making the leap.I have a list box that receives entries from another text box, there will be multiple entries, and only some will be applicable per record(its a report writing app).e.g. The user says ok I need this and that signer for this record.
lstSigners.Items.Add(strSigner + strSigner)
The entries that are needed are then selected via checkbox in the listbox. I now need to be able to capture which items the user selected.

I have five listboxes that are populated from five different datasources basically I have connected to an MS Access database and I am running SQL queries effectively so the five listboxes are populated via datatables for example dtInterests, dtHobbies, dtMovies, DtTV and dtMusic my question is how would I compare the values that are being stored in each listbox I want the application to check each of the five listboxes and if the value is the same (in my case the valuemember is the customer id) then store the result somewhere (in a textbox)

My problem is, i want to also get div id="2" value at the same time and add it to my listbox, since the Persons ID is in div 1 and the Name of the person is in Div2.

Question is, how do i add to a value or position in a listbox, after its been filled?
I'm trying to create a calculator that does this formula : Amount=Principal*(1+InterestRate) The point of it is to Calculate the compound interest earned over however many years the user selects between 1-15 from a listbox. The user also inputs the investment & interest rate. When calculate is clicked the results show in another listbox below.
year 1 $$$$$$
year 2 $$$$$$
etc

I stopped the code at Year 2 as it repeats the ElseIf to EndIf unitl selectedIndex = 15 & intYear 16.
it works for Year 1 but the problem comes with Year 2-15. it needs to take the value from the previous result in lstOutput and use it in the formula for principle.
