Can't Save Data To Install Folder - Can't Find Data After Written
May 19, 2011
I've written a very simple program that writes a tiny "config.cfg" (text) file to the computer (using StreamWriter), and a second program that is supposed to read that data back.
Unfortunately, it appears you can't save to the same folder as your program under Win7 ("Program Files (x86)" is a restricted folder.) So instead, VB automatically saves my data to the "C:Users(myname)AppDataRoaming..." folder. This is annoying, but tolerable.
PROBLEM IS: How does my second app then FIND my data file (without doing a time-wasting drive search every time the program is run?)
My code:
' Program #1:
Private Sub cmdSave_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdSave.Click
Dim FileWriter As New StreamWriter("config.cfg")

I have written a small project that saves data in a data set, this part works fine, but I have some errors with the code I have written for importing excel data to the datagridview and exporting data from the data grid view.
This is a test project for me to learn how to do this stuff, so I will post the code for the entire project so you can see what I have done from start to finish.

VS 2008 VB/I've implemented an interface to a .com program written in c++. I'm trying to access a data structure array(uNewValues) of type PLCCOMMLib.ANALOG_CONTIN. uNewValues should be a datastructure array of several elements (iSigIDCount). My problem is I only get the first array element of the datastructure.I've tried several methods and looked into marshalling but don't understand how to implement marshalling if that is the correct option.
Code below:
Public Sub AnalogContinUpdate(ByVal iSigIDCount
As Integer,
ByRef puTimeDateStampGMT As PLCCOMMLib._FILETIME,
ByRef uNewValues As PLCCOMMLib.ANALOG_CONTIN)

I have a small program on the menu written in VB6 retrieve data from Acess run very fast and now want to switch to VBNet2008. VBNet2008 conversion is still normal, but when running the menu does not appear that waiting in line, then click on the menu bar of this menu appears, but not the font is in Unicode data is available. Expect you to help debug programs that run on VBNet2008 still running good access Menu fast as running on VB6. Also supported is Unicode font on VBNet2008 does not function for unicode font. Attach program with VB6 and VB2008.

I recently switched to V.Studio 2008 and using VB. I can not find in the data toolbox the connection and data adapters. Should I do something else to make this appear so I can drag them in my form.

There are few steps to find out the half slopes of the graph.
Step 1: Rank the data The independent variable is required to rank it from the lowest to the highest.
Step 2: Divide the data Divide the sample size into 3 roughly equal parts, which is the lowest, middle and the highest parts. If n/3 has remainder of 1, +1 into the middle part. If n/3 has remainder of 2, +1 into the lower part.
Step 3: Find the median The size of each part = n, find the ((n+1)/2)^th value for both dependent and independent variables. If the ((n+1)/2)^th is not an integer, sum up the 〖n/2〗^th value and ((n+2)/2)^th value and divide the total by 2 to make it as median. The median, m1 for independent variable in lower part indicate as XL , middle part median, m2 as XM and the highest part median m3 as XH. For the dependent variable the median is indicate as YL, middle part as YM and the highest part as YH . Figure 3.2 Example of median m1, m2 and m3
Step 4: Find the half slope Find the half slope for the lower half, b_L=(Y_M-Y_L)/(X_M-X_L ) and for the upper half, b_H=(Y_H-Y_M)/(X_H-X_M ) .
Step 5: Find the half slope ratio, b_0=b_L/b_H . If the ratio is negative, the dependent variable need to add with a constant, c in order to make the slope same direction.
Step 6: Identify transformation. Depend on the graph pattern pick one type of transformation which is nearest to the original of the variable.
Step 7: New half slope Find out the new half slope ratio, b1 by repeat step 4 and 5 with the transformed variable.
Step 8: Repeats steps Repeat step 6 and 7 with choose the transformation which is nearest to previous transformation and find the new half slope ratio, b2, b3,�, bn. Repeating this step until |1-b_i |≤|1-b_j |, for i<j, i and j = 1,2,3,
Step 9: Result bi is chosen. The data transformation used in bi is the most closest to be normality.
How to make it into visual basic and let it run by the program?

I am a sys admin for a company and our programmer left several months ago. a program they wrote is now failing and i am struggling to work out why. the program basically pulls data from a csv file into a readable form, written in visual basic. the application works on a couple of machines but not on a couple of others. i have matched up .Net framework versions, MS Primary Interop Assembly versions, still no joy. As the app works on some pc's i am wondering what other differences could cause this?
The error output is:
see the end of this message for details on invoking just-in-time (JIT) debugging instead of this dialog box.
Exception Text
CODE:
JIT Debugging
To enable just-in-time (JIT) debugging, the .config file for this application or computer (machine.config) must have the jitDebugging value set in the system.windows.forms section. The application must also be compiled with debugging enabled.
For example:
CODE:
When JIT debugging is enabled, any unhandled exception will be sent to the JIT debugger registered on the computer rather than be handled by this dialog box.

in my form i have 4 textboxes and i want all not to be empty while saving the data.I have put condition in save button,when user presses the save button to save data, to check all the textboxes not to be empty. My question is that, i want to focus to that particular textbox which is empty during saving the data.
For example: i have txt1,txt2,txt3,txt4 as textboxes in the form if txt1 is empty while saving, the focus should switch to txt1 rather user himself have to go there.

I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:

999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.

basically how do i do this, i have no idea at the moment, Get a listing of all of the files in the data directory. Determine the total number of lines among only the csv files. For example, suppose the data directory contained three files:a.csv , containing 3 lines; b.csv , containing 5 lines; and c.txt , containing 7 lines. Then the total number of lines among the csv files is 8, not 15.

I wish to know what location does the "|Data Directory|" in "|Data Directory|XYZ.sdf" that shows in the connection string when I create a dataConnection using the wizard in VB 2010 Express. Is it the Application's directory in Program Files or is it the AppData folder of the client computer.If it is the Application Directory in Program Files then the client user wont be able to write to the database without Admin rights. If so how do I make a dataConnection to a file in the AppData folder using the new data connection wizard.
