I am a newbie so please forgive me if my terminology is incorrect.I am trying to Update a Registry sub key value. I have done this a few times before with success. But this time is kinda different. I noticed a few things,like the sub key value is in HEX when I export the key (The value that I want to input is from a sub key that I exported) I can only get the registry to accept the command if I do not specify the registry value kind, but that doesn't do me any good if its not the correct value kind.
I've had a bit of a look around the net and on the forums but I've yet to find an answer to my question. I've got Visual Basic 2008 Express and I'm trying to write some registry entries, I can write strings fine just using
I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out...
I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically. here is the culprit!
I have a DEM file(Digital Elevattion Model File) and I am trying to open the file,where we have Latitude and Longitude values inside the DEM file.And, Now I have opened the file using Filestream and Read the file using BinaryReader.But, I am having a trobule in getting the values of Latitude and Longitude.I am getting Byte values randomly as 1,202,31,271 etc.But, we dont have latitude and longitude values more than 180,and also I am not getting 16 bit UInt values.For example, the values should be like Latitude 20.00416666666667 and Longitude 39.99583333333333.So,read the correct Byte values of the DEM file.The code I have used till now is:
Dim fs As FileStream = New FileStream("C:UsersadminDesktopHeader and DEM fileE020N40.DEM", FileMode.Open, FileAccess.Read) Dim rd As New BinaryReader(fs) Dim convertDB As UInt16 For i = 0 To rd.BaseStream.Length
I am working on a vb.net project where I am trying to set a registry value to set the Internet Explorer Proxy server and exceptions for all connections. I am able to do the string registry keys but have been unable to get the binary keys to set. I have the Registry key exported that I need "merged", but I am not sure how to code setting the binary key.Public Class Form1
I've never worked with Binary values, so I can't get this to work. I don't know how to write it, but when I open the registry, I want the Data to look exactly like this [code]...
I'm trying to write a value of to a REG_Binary key. the only viable solution i see online is the following: Dim a() As Byte = New Byte() However the value of a0 is causing a problem. It won't seem to let this value be used. so how do i get this to work.
I have a serious problem reading that stuff, it seems I can't get it right.The registry key I want to retrieve looks like this: And this is the code i used:
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim readValue = My.Computer.Registry.GetValue _[code].....
The problems is that it returns something like: "V???????=dQ???!u?1?" What the ____ is that anyway? So in reality it should be like "c3gm322dvf" or something like that.
i want to make a VB code that enters the Binary type data in a subkey with the name as NoEntries and data as some string like 02 00 00 00. I have written a code :
I am working with binary files that have 500 rows and 500 columns (width x height). When I load these files into array I set width and height variables to 500 and I was wondering instead of hard-coding like that how I can code in a way that the program should find the # of rows and # of columns of the file before loading the file into array...
I wrote an application to manage several installers and I wanted to throw in some registry settings as well. Unfortunately the following code is not writing to the registry, nor is it returning any exceptions.I'm running Visual Basic 2010 Express as administrator using Windows 7 64 bit, I can manually add the values, and I can add them from a .reg file manually but not even by calling the .reg file as a new process (it asks for permission, says it succeeded, but nothing changed).The key already exists, all I need to do is add two values.
I'm trying to assign some parameters for a stored procedure with some values that are stored in a data table. in the code, I can set the parameter values to the data table, and give a column header or index without issue, but when it tries to execute at runtime it bombs out.the error I get is a variation on "Failed to Convert Parameter Value from a DataColumn to a String" depending on exactly how I try to assign the value.the data types are all correct elsewhere in the code.
my code for this bit is
Try ConnectionAttempt.Open() Try With NewYearCommand_Dates
[code]....
other things I've tried to get this to work are all variations on the .Value=dates bit, such as
.Value=dates(0) (so using column index) .Value=dates.columns(0) (again using column index)
I've also tried declaring variables, and setting their values to the values in the columns, but the code returns an error saying that "Value of type 'System.Data.DataColumn' cannot be converted to string".I should point out that i'm doing this for 3 tables at once in this sub, 2 of them will only have a single row of data, but the third has an indeterminate number of rows.I'm afraid I don't know what else to do. I'm lead to believe by my mate and my lecturer that this should work, and of course it will work, but the evidence says otherwise.
im trying to make a vb 2010 program to startup with windows with that is the user choice and i have got this code from the net:
[Code]...
i havent got a clue on why its opening on the wrong path at startup, but if i close the app and i open it manually by its desktop icon everything is fine again :S
I want to change this registry setting in windows vista and 7 ("HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesUSBSTOR","Start",4) by clicking a button.[code]how do i change ("HKEY_LOCAL_MACHINESYSTEMCurrentControlSetservicesUSBSTOR","Start") value to 4..How do i request administrative privilages for my aplication to change registry setting when it starts?
In Windows 7 you can pin a program to the taskbar so it appears like a quicklaunch item. In my program I need to get a list of all the programs that are pinned to the taskbar. Does anyone know how I can do this programatically, either through an API call or through a registry setting?
I have setup in the registry editor in VS 2008 to create a key and string value.. I see the property for a condition. I want to have a setup screen that asks what location the client will be installed in and create registry value based on that..
on setup i have a dialog for 2 radio buttons..
button1 & button2 value 1 = Houston value 2 = New Orleans Select location. * New Orleans * Houston
I set the font size and style using Vb code as i'm designing a Notepad like application, and when i start a new form i want to reset all the settings. Everything else is working, i'm just having a hard time working these out.
MSDN states that the return value of System.Windows.Forms.SystemInformation.MouseButtons is INTEGER. I expected that, but I also expected that they would talk about the binary values for each button. My mouse has a mouse wheel, so technically I have 4 "buttons". The return value I get is "16". But this doesn't add up (at least the way it used to add up in vb6) so I wish MSDN took it that necessary extra step to clarify the logic behind the returned values for .NET. For instance, if I add up mouse button values based on binary assignments:
CODE:
So for a 3-button mouse + wheel, why is the return value for .MouseButtons, "16"?
I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
I have a binary converter I am attempting to build and want to read and convert the InputTextBox(alphabetical characters) letter by letter however all I have so far is one letter at a time
Image here is the code I have so far:
Code: Public Class ConverterForm Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click
I am attempting to read a series of double prcision float values (x,y,z coordinates) from a binary file using the binary reader. Everything works fine except that when I read the number back it is different then the number that was written there (original file is generated by mining application).
written number : 78897.6476586 file contents hex : 40 F3 43 1A 5C CF 43 A4 this converts back to the same number as written using a IEE 754 conversion program. VB returned value : -5.45100266729248E-134 using .readDouble()
I have tried to step thru the file in one byte steps to make sure that I have the proper start position but that did not help any.
I have a delete method for a binary search tree that only deletes the last two values that were entered in, and when it tries to delete anything to the left of the root or even the root itself it returns a null pointer exception.
Public Function Delete(ByVal key As Integer) As Boolean Dim current As Node = root Dim parent As Node = root Dim isLeftChild As Boolean = True
