View 2 Repliesgood way to run windows script host code from vb.net? Im trying to run some dsf com components but they are only for the 64-bit version of scripting engine installed. I wish i could execute my code from vb.net but sometimes it doesnt want to work because im referencing the 32-bit version script control and not the 64-bit scripting environment.
So my goal out of this is to find a 64-bit scripting component dll or library that i can use for executing a wsf file thats mostly written in vbscript but has some xml from the windows script host.Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth. - "Sherlock holmes" "speak softly and carry a big stick" - theodore roosevelt.

say you have a sub containing an io.streamwriter. That streamwriter is declared and used only inside that sub (and not as static). Should you still call dispose on that streamwriter or is it disposed automatically as it is no longer in use after that sub, until you call that sub again?
View 2 RepliesI am trying to understand how to interact with external DLLs written in C++ for use in my VB.NET application. I have some DLLs that a client wrote that do some math functions. Everything was working on a 32-bit machine. Because we were taxing the 32-bit machine we moved to 64-bit. Now we can't get the same functions to work. The DLLs were re-compiled as 64-bit DLLs and they still don't work. So my client wrote some dummy DLLs to see if we could figure out the problem. Here are the "signatures" of the DLL calls that I am making:[code]....Ultimately I would like to get to calling initialize_quiet and I am guessing at the format of the marshalling, const size etc.

View 18 RepliesWhat I am trying to do is have a class where the functions of the same name are both instance functions and shared functions.
Public Shared Function Get...(byval xx as xx)
and
Public Function Get...
The Public Function uses a Property xx created in the constructor, whereas the Shared Function has the parameters (byval xx as xx).
I am new to .NET 4 and VS 2010. I am using VB 2010 and have made a class and need to know how i can access those functions in the class within another form. So there is a function say of XYZ in the class named classes.vb and need to get to it from form1.vb
View 9 RepliesI have recently started learning VB.NET. I created a simple 3 tier windows application. The DAL project contains a class with a number of functions. In the BLL project, I've added a reference to the DAL project, but I still can't access the functions in the DAL class from the BLL. However, if I change the DAL class to a module, I can access them then. Both the DAL class and its functions are public.

View 6 RepliesI've been researching for days and I've gotten to the point where my WCF service creates an Access object via com/interop.I've ran the Open Current Database call for the Access object without an error but Application.CurrentDB is still nothing/null. If the CurrentDB is nothing then I surely can't call Application.Run "myFunction" I realize WCF services aren't meant to be user interactive, but it's a long story why I'm trying to go this route. Basically I need to have a proof of concept ready sooner rather than later and the alternative (correct) route involves the complete re-writing of a large complex access VBA application. It's not a permissions issue, I have the IIS user names added to the security tab. What I really need is a way to set Environment.UserInteractive to true so my WCF service can create an instance of Access on my server machine, run the VBA functions, close out, return true.I'm using VS 2010 for the WCF, IIS 7 for my server, Access 2010 for the VBA application.

View 3 RepliesI'm trying to develop a program that turns matrices into their reduced Echlon forms. The user specifies the number of Columns & Rows for the matrix, which is generated by the following Sub Routine
Private Sub ButCreate_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles ButCreate.Click
'Columns and Rows are specified by the user
rows = TxtRows.Text
columns = TxtColumns.Text
'clears all of the controls(text boxes) from the TableLayoutContainer
[Code] .....
How to do is access/manipulate those newly created textBoxes. After the user enters values to those boxes, I want to assign each of their columns to an array.
I have an application which is grouped in a MainApplication and serveral Modules (DLL's) The Main Application is basicly a Form with a NavigationBar on the Left Side (like in Outlook 2003) and an MDI-Parent. There is also a Simple Login Routine on this Form. I store the UserName after Loggingn to a Property. The DLL's holds functionallity and Forms for various Sections for example there is a Employee.dll which holds functions and a form to show all Employees.
On Loading of the Main Application I loop trough all dll's in a "Module"-Folder and extract NavigationItems from them which I add to the MainForms NavigationPanel. I don't have a reference to the Modules because I want to make it as flexible as possible so that it is possible to delete a Dll form the Module directory in order to remove the functionality from the MainApplication. The Modules could work also without the MainApplication if they are Complied as an exe insted of DLL of course. This works fine so far.

View 4 RepliesI opened vs 2008 and used the server explorer for the first time to create a connection to my SQL 2005 db. The solution explorer pulled in all the tables, the database diagram etc. My question is how do I access that database connection and work with it using ADO objects? Do I need a reference to ADO?
View 4 RepliesI don't know if I explained this in my title, this is what i want to do. (In VB on a active server page) I have 5 buttons called but1.....but2. Right now I have the following code to make them invisible
but1.Visible=false;
but2.Visible=false;
but3.Visible=false;
but4.Visible=false;
but5.Visible=false,
Is there a way to access the objects by using a string, example
for(i=i;i<6;i++
items("but"+str(i)).visible=false
I have a Repeater Control which I bind to a list of Products
Repeater.DataSource = ProductRepository.GetProducts();
Later (in another module), I need to retrieve the products from the Repeater, but it seems not to work with Repeater.Item.DataItem (which is then null).
My question is, is there any reference to the products in the Repeater-Items? Or do I have to set it myself via id field etc. What would be the easiest way to get the "underlying" product objects?
I was given a ppt slide with 12 chart objects and a text box for each. see the zip attachment. This is a collection of metrics that we track and chart monthly. The previous custodian of this duty would manually open each and update the datagrid for each and add comments as needed. I want to automate this process using vb2008 express. I have a basic handle on windows forms and sql tables, but don't have a clue how to access these chart objects and text boxes in the ppt slide. I've tried adding the slide to my project - like an image, but nogo.
I thought I could update the slide using my form controls, taking data entered on the data grid, create my SQLdb and update the slide. There is a one to one relationship for each item on the form and the ppt slide - 12 ea (charts & boxes) on both. My issue is how to define the chart object (mschart) in vb and update the ppt slide.
url...If you check out the images on that website you will notice that in their program, it has the textbox and user icon thing and everything and they have transparencies set.Is there anyway to access those "objects" and just throw it on the screen? How exactly are they doing that? Did they make their own graphics? And if they did, how are they letting it do the transparency, because I know laying a picturebox over a picturebox won't accomplish that.

Access objects on a dynamically created UserControl an a dynamically created tab page. I can usually find the answers to most of my questions via the Google Gods, but not this time. I hope the collective that is StackOverFlow can help! I have a form that has a TabPageControl and on that page a collection of labels and text boxes via a usercontrol.
On the form I have a button that allows the user to create a new tabpage, when the code adds a new page, it automatically adds the UserControl collection, all good so far. I can't get my head around how to access the objects on the newly created tabpage. What I need to be able todo is take the index of the tabpage that has focus and translate that against the UerContol name, but I havn't a clue how to do it! [Code]
I have a class assignment and I am having some difficulty with an Access 2010 database and OLE objects in the database. I have the database imported into the project and I am able to view the records from the database that I have in labels and combo boxes.
I used the database DataSoure wizard to create my connection string and import the Access database. In the DataSouce window I set the DataSet for the "Flag" column that contains my pictures to use a picture box object type and added the data bound object to my form.
When I run the application all the field from the database show as expected however, the picture box object does not display the images from the database. When I check the picture box object in the designer the properties window shows that the image source is bound to my database with the little database icon and the data bindings are all correct.
1) Is it possible to access the Excel mathematical functions without actually opening Excel?
I was thinking of through a DLL WinAPI call or maybe a delegate function or smaller program?
2) Does anyone know of a MS link or area that gives instruction on "how to" use every function of every Windows DLL at all?
Or for all those that Microsoft have chosen to document online at least.
While converting types, I have found myself using both VB functions and BCL Convert.To* methods.
E.g.)
Cstr() vs. Convert.ToString()
CInt() vs. Convert.ToInt32()
CDbl() vs. Convert.ToInt64()
etc...
Are there any subtle differences that should be noted?
Is there a way to see exactly what the functions are doing. What i mean is there a way to see the class? I know what it does, i just want to know the code.
For example the function: Membership.FindUsersByName()
